Everything born, lives, and dies. During its' period of life, it encounters the forces of nature and energy surrounding it, which may impact it in a negative or positive direction. Everything living has its' personal degree of tolerance as nature has incorporated into it. The better a living system is able to adapt to life and its' surrounding changes, the stronger and longer it can survive. Plants are one of the essences of nature and constantly encounter natural free energy that is around it. Curiosity creates a wonder as to what genetic aspect in them, is able to aid in their survival to few of nature's stressors such as excessive sun light.

Stress Physiology in Plants

3549 руб.
In both natural and agricultural conditions, plants are frequently exposed to environmental stresses. Some environmental factors, such as air temperature, can become stressful in just a few minutes; others, such as soil water content, may take days to weeks, and factors such as soil mineral deficiencies can take months to become stressful. Thus, understanding the physiological processes that underlie stress injury and the adaptation and acclimation mechanisms of plants to environmental stress is of immense importance to both agriculture and the environment. The concept of plant stress is often used imprecisely. Stress is usually defined as an external factor that exerts a disadvantageous influence on the plant. In this book we will examine these principles, and the ways in which plants adapt and acclimate to water deficit, salinity, chilling and freezing, heat, and oxygen deficiency in the root biosphere. We will also see that plants often display cross-tolerance that is, tolerance to one stress induced by acclimation to another. This behavior implies that mechanisms of resistance to several stresses share many common features.

Cadmium is a major industrial pollutant, and is easily taken up by plants and accumulated to high levels in the aerial organs thereby causing potential damage. When exposed to stressful conditions, plants accumulate an array of metabolites, particularly amino acids. Proline, an amino acid, plays a highly beneficial role in plants exposed to various stress conditions. Proline, when supplied exogenously at lower concentrations to plants exposed to various biotic and abiotic stresses, results in stress mitigation thereby enhancing growth and other physiological characteristics of plants. Salicylic acid is ubiquitously distributed in the entire plant kingdom. It was recognized as a plant hormone. The exogenous application of SA at suitable concentration has been found to enhance the activity of the antioxidative defense system thereby providing tolerance to the plants against oxidative burst.The work reported here focus on synergistic interaction between hormone, amino acid and metal. This book is useful research documents for students and researchers working in the area of environment

Selenium supplementation in rice during arsenic stress

3549 руб.
Arsenic (As) contamination of rice is a major problem for South-East Asia. Effect of selenium (Se) on rice plants exposed to As. Presence of Se decreased As accumulation by 3-fold in roots and 2-fold in shoots as compared to single As exposed plants. Arsenic induced oxidative stress in roots and shoots was significantly ameliorated by Se supplementation. Positive response was found associated with the increased activities of antioxidant enzymes, induced thiolic ligands and phytochelatins in As+Se exposed plants as compared to single As treatment. Selenium supplementation modulated the thiol metabolism enzymes Gene expression analysis of several metalloid responsive genes showed upregulation during As stress, however, significant downregulation during As+Se exposure as compared to single As treatment. Gene expressions of enzymes of antioxidant and GSH and PC biosynthetic systems and PCS were found to be significantly positively correlated with their enzyme activities. The findings suggested that Se supplementation could be an effective strategy to reduce As accumulation and toxicity in rice plants.

Global Warming is one of the challenges that we are facing in today’s era. The effect of global warming is not only limited to human beings but its effect can also be seen on plants. Increased temperature causes heat stress in plants and this ultimately decreases the quality and quantity of crops. The need of this hour is to develop crop plants with enhanced thermo tolerance. In this report we have used data mining techniques to show that heat stress is an important stress affecting the agricultural production. At the molecular level post translational modifications have been shown to be influenced in plants under heat stress. We have studied Palmitoylation, Sumoylation, S- Nitrosylation and Nitration in the plant gene sequences associated with heat stress and not associated with heat stress. We show that sumoylation is an important property which is possibly influenced in large number of proteins associated with heat stress in a wide variety of plants. This property can be used for identifying novel sequences associated with heat stress in plants.

The book is about complex antioxidant system development in Plants under heavy metal stress by which they scavenge ROS thereby protecting cell from oxidative attack. A common feature of different stress factors is there potential to increase the production of reactive oxygen species in plant tissues. Reactive oxygen species are also generated in plant cells during normal metabolic functions especially in chloroplast during photosynthesis. ROS are produced as intermediate products in a number of metabolic reactions in various cellular organelles, generated by oxidative stress in plants. Heavy metals are known to generate these toxic ROS such as H2O2,O2-, OH- etc which degrade important cellular components by including oxidative stress. In order to control the level of ROS and protect cell from oxidative injury, plant and developed a complex antioxidant defense system to scavenge the ROS and result in the degradation of sulphate reducing enzymes leading to toxic effects. Cr at both toxic and mild concentrations can inhibit uncoupled electron transport indicating electron transport chain to be a common site of chromium binding in plants.

The unique morphological manifestations called “ Mycorrhizae” represents one of the nature’s most widespread phenomenon of symbiosis. VAM fungi largely help plants in both, nutrient mobilization and cycling through their extrametrical hyphae. VAM fungi increase the absorption of immobile elements in soil such as phosphorus, copper and zinc. Plants respond to the VAM fungi more in sites exposed to stress conditions such as drought, salinity. VAM fungi was also reported to reduce severity of plant diseases particularly diseases caused by soil- borne pathogens since mycorrhizal roots are more lignified than non-mycorrhizal roots. This resistance to pathogen is primarily due to improvement of host vigor and development and production of inhibitory substances. Because of these attributes, mycorrhizae are today considered an important component in the re-establishment of plants especially those plants growing under inhospitable sites such as sand dunes and other stressed locations. The objectives of this work are to identify VAM fungi widely colonizing plant roots under stress conditions to investigate the potential role of mycorrhizae for alleviating stress conditions.

The thyroid hormones play a pivotal role in the generation of oxidative stress on exposure to stressor. It was further observed that vitamin E treatment eliminated the stress induced oxidative stress while the raised levels of T3 and T4 remained unaffected.The present investigations provided enough evidence to show that the supra spinal response to stress basically elevates the thyroid hormone levels, which onward causes the oxidative stress. Such conclusion further suggests the use of antithyroid agent to prevent the stress induced oxidative stress and subsequent tissue degeneration. However, it is cautioned that the levels of thyroid hormones must be first assessed in stressed exposed subjects before any antithyroid agent is used to prevent the oxidative stress as the hypothyroidism after the inappropriate dose of antithyroid agent is likely to impair the stress- sustainace ability.

The early detection of these stress factors with non-destructive methods is crucial because it could help to identify stress status at larger temporal and spatial scales before any damage is clearly visible. in this regard, precision agriculture and precision phenotyping technologies for crop management have the potential to provide more information for making more informed management decisions on a canopy scale in real time. Time-consuming destructive methods could be replaced by proximal remote sensing methods using spectral reflectance and laser induced chlorophyll fluorescence measurements. These technologies may open an avenue for fast, high-throughput assessments of water status in plants, which would simultaneously be useful for screening large numbers of plants (e.g., in breeding) as well as being equally important for management related actions

Salinity and drought are the two most common abiotic stress conditions which have devastated growth and yield of crop plants. Though, plants bestowed with the capability to respond to abiotic stress via signal transduction pathways by adjusting their metabolism. A defensive strategy of plants against such stressful events encompasses a cascade of signals ranging from primary to secondary responses. In extreme environment, fungal symbioses with crops can influence various physiological adaptation and improve plant growth. Thus, reducing the adverse effects of stress. Among fungi, endophytic fungi are the fungal symbionts associated with plants, lives inside tissues or roots and can enhance plant growth during stress conditions. Such association in roots can change key features of plant physiology and mediate abiotic stress. Though, endophytes are novel source of biologically active metabolites but there are few reports elucidating the effects of plant growth regulator specially phytohormones producing endophytic fungi. The present work shed light on various overlooked aspects of these endophytes.

Water is a major limiting factor affecting plant growth, development and yield mainly in arid and semi-arid region where plants are often exposed to periods of water deficit stress which is also known as drought stress (Foyer et al., 1994). Drought and heat stress can cause oxidative stress through the production of reactive oxygen species such as super oxide radicals and hydrogen peroxide. Also the drought, salinity, extreme temperatures and oxidative stress are often interconnected and may induce similar cellular damage. Plant growth and productivity is adversely affected by nature''s wrath in the form of various abiotic and biotic stress factors. (Serrano et al., 1999). The effect of water stress in contrast to roots; leaf growth is severely inhibited at the onset of drought. Leaf cell expansion during water stress is regulated by changes in pH and inhibition of growth is mediated by a rapid decrease in extensibility of expanding leaf cell walls.The study was conducted to determine the effect of drought stress on the growth and development of Gampherena globosa. The data recorded for different growth parameters of the plant.

Impact of heavy metals on growth and metabolism of crop plants

4839 руб.
The consequences of urbanization and industrialization, heavy metal contamination in the environment is a worldwide problem. Some heavy metals are essential macro-nutrients (trace metals) for normal plant growth. Their deficiency or toxicity poses adverse effects on growth and metabolism of plants. The elevated levels of these heavy metals contaminate the environment and cause great environmental problems. Plants exposed to excess concentration of a heavy metal, accumulated it in their tissues often to the toxic levels, causing a reduction in growth, biomass, yield-productivity and metabolism. Hence, keeping this view the study of impact of heavy metals on growth and metabolism of crop plants should be taken with goal to achieve high growth and yield of crop plants improving living of standard.

On the Role of Visible Light & UV Radiation in Germinating Vicia faba

6690 руб.
Life on earth depends on the solar energy which is fixed in the biosphere by photosynthesis in plants which have pigments that harvest sunlight. Thus, plants are constantly also exposed to ultraviolet irradiation. In plants wide inter- and intraspecific differences have been reported in response to UV radiation with respect to growth, production of dry matter and biochemical changes. The direct effects of UV radiations on plant cells are mostly damaging, because UV photons have enough energy to create lesions in important UV-absorbing biomolecules. Also, the present work ascertains that plants employ strategies of protection to counter the detrimental effects of visible light and UV radiation absorption. In spite of being much information available on the influence of either UV-B radiation or visible light intensity on plant tissues, yet no appropriate information is available on the influence of UV-C and UV-A. This monograph is to provide students having diverse backgrounds and interests with a clear insight into the present state of our knowledge in the subject, and to highlight the problem areas where current research effort is either located or needed.

Calmodulin(CaM) and Ca2+ have been implicated in adaptation of plants to changes in its environment. Arabidopsis thaliana (Arabidopsis) genome has nine genetic loci encoding calmodulin protein isoforms. We have used wild type (WT) and T-DNA insertion mutants of seven calmodulin genes in Arabidopsis to determine role of specific isoform of calmodulin in abiotic stress in Arabidopsis.The obtained results suggest that collective amounts of CaM proteins may regulate GAD activity in response to abiotic stress rather than specific CaM protein under different stress conditions. Steady-state level of CAM mRNA in WT and cam mutants provides support for some level of compensation in expression CAM genes in Arabidopsis thaliana.

In saline soils, banana suffered from salt injury with the external symptoms. The caroteniod content was decreased in all the treated plants except in control. In all the NaCl treated plants the chlorophyll pigments was significantly reduced. In abscissic acid(ABA), treated plants chlorophyll content was significantly increased. Membrane Stability Index(MSI) was decreased when the salt stress period increased. In case of Cholorophyll Stability Index(CSI) and Membrane Stability Index(MSI), the butylated hydroxyl toluene(BHT) increased over the other chemicals treated in NaCl stress, where as in acetyl salicylic acid (ASA) increased MSI only. The ASA capable of inducing more ascorbic acid production in more NaCl stressed plants. Peroxidase and superoxide dismutase activities were decreased significantly over the period of stress increases. In BHT treated salt stressed plants observed significantly higher nitrate redcutase activity. The persent investigation showed that the abscissic acid(ABA), acetyl salicylic acid (ASA) and butylated hydroxy toluene (BHT) have the potential to reverse the effect of salinity in Grandnain banana plants.

Increase in environmental pollution as well as contamination of water by heavy metals, associated with plants and other food products due to increase in human anthropogenic activities, has resulted in damages to natural resources. Plants, be aquatic or submerged ones, are the best indicators of such unseen killers, and as such develop tolerance to such metabolically toxic pollutants, including heavy metals. Aquatic ecosystem is susceptible to such pollution, precisely because of different effluents draining off finally to some water bodies that subject the flora of that system to encountering toxic substances. Screening followed by the proper monitoring of the impacts of these heavy metals is very important. Therefore, approaches to develop plants with reduced heavy metal uptake are important. “Plant Heavy Metal Stress” aims at giving an overview of the most important basic aspects of physiological and biochemical basis for such contamination, toxicity and tolerance in widely grown aquatic model plants. The book is expected to serve as a reference to researchers and students of plant sciences and environmental stress.

Optimum fertilization management is an important technique to alleviate the adverse effects of salinity stress on plants. An experiment was conducted to evaluate the ameliorative role of inorganic and organic P-sources on wheat grown under salt stress in three soil types deficient in available P. Wheat plants were grown on alluvial, sandy and calcareous soils under salinity levels of 4, 8 and 12 dS/m of saturated paste extract (ECe) and supplied with constant rate of superphosphate (SP), cattle manure (CM) and 1:1 mixture of SP and CM. The results revealed that plants grown on the sandy soil were more susceptible to the adverse effects of salinity compared with that planted on the alluvial one, especially at 0 P. However, plants grown on the calcareous soil were moderately affected. In addition, varying soil type caused significant differences in the aboveground biomass and uptake of N, K, P and Zn in shoots and grains, where maximum values were attained in the alluvial soil followed by calcareous soil. Grains and straw yields and contents of N, P and K in the shoot tissue, grains and straw decreased significantly with increasing ECe from low (4 dS/m) to high level (12 dS/m).

Stress is a common human condition in private and public life. Good stress is that strain or pressure that energises human being to rise to their higher levels of exertion or creativity. But stress can be bad in the sense that it can cause such strain in the human being that it leads to a feeling of being overwhelmed and sometimes to outright illness and death. Stress at its various levels is always part of the occupational condition of humans. The world over, but more so in advanced countries, the teaching profession has been found to be stressful compared to jobs that require the same qualifications and experience. In developing countries much less work has been done on teacher stress and in the general and working populations. The quality of education delivered by teachers is to a good extent dependent on how stressed the teachers feel and how they cope with their stressed condition. This study therefore, sought to establish the stress levels felt by teachers in high schools (deemed the most stressful part of the education system for teachers in other countries). The factors of stress were also identified and compared for men and women and so were the coping mechanisms.

Malathion, widely used organophosphorus insecticide worldwide, induces oxidative liver damage type; Cimetidine is an antagonist of histamine H2-receptor, it has been shown to be an inhibitor of various CYP450 isoforms. Male Wistar rats weighing 200-250 g were studied, exposed to malathion orally for 3 weeks (0.15 mg/kg/day, 2 mg/kg/day, 15 mg/kg/day) and cimetidine 10 mg/kg/day. Malathion affects susceptibility to oxidative stress and possibly modifies the antioxidant defense capacity directly or indirectly.

Seagrass meadows are of economic importance and high conservation significance, and offer a sensitive bioindicator for estuarine ecosystems. Successful management depends on appropriate monitoring of the health and extent of seagrass meadows. The research in this book advances the field of remote sensing of seagrasses, and is applicable to plants more generally. Hyperspectral reflectance studies are combined with ecophysiology and biochemistry to generate essential baseline data, facts and tools that optimise the mapping of seagrass meadows and lay the groundwork for monitoring the physiological condition of plants. These include the first spectral library of aquatic plant species to account for the range of spectral variability expected for a species under natural conditions, a comprehensive characterisation of spectral, biochemical and physiological changes in light-stressed eelgrass, and a new plant stress index. This book will be invaluable to researchers and students investigating the remote sensing of vegetation or those examining seagrass health and dynamics, and offers a useful guide to managers developing monitoring programs in shallow aquatic ecosystems.

Photosynthesis is the process by which plants sense and respond to changes in atmospheric [CO2] concentration, climate, and soil, and therefore, understanding how this process is affected is very important. This book examines the effects of changes in temperature, [CO2], light intensity and nitrogen nutrition on photosynthesis, based on experiments involving gas exchange and fluorescence techniques on plants grown at different climate and nitrogen nutrient condition in a controlled growth chamber. Short-term responses of photosynthesis and long-term acclimation to [CO2] and temperature are examined. Scaling up from the leaf to the canopy level is simulated using the sun-shade and big-leaf model presenting algorithm for calculating diurnal canopy assimilation rate using parameters from the single leaf light and [CO2] responses, the canopy extinction coefficient for light and nitrogen, canopy leaf area index, canopy nitrogen concentration , daily solar irradiance and daily maximum and minimum temperatures; taking into account the significance of diffuse radiation in canopy assimilation rate and efficiency.

Oxidative stress has been implicated in the progression of several diseases ranging from mild inflammation to several inflammatory acute immune diseases to grave disease process like cancer.The steady state levels, or extent of accumulation of oxidation products in tissues and plasma or the changes in the antioxidant status are commonly used as measures of increased oxidative stress. In fact, the measurement of lipid peroxides, conjugated dienes, and markers of nitrative DNA damage are considered to be the cornerstone of the assessment of oxidative damage in vivo. Oral Lichen Planus (OLP) is an inflammatory disease of unknown etiology while Oral Lichenoid Reaction (OLR) is a condition mimicking OLP. As these conditions are exposed to oxidative stress, they could release reactive oxygen species (ROS) which are implicated in the pathogenesis of a plethora of inflammatory conditions to lethal diseases. We evaluated and compared the levels of a series of oxidative stress markers in patients with OLP and OLR with that of normal controls and tried to identify the role of these oxidative stress markers in these conditions.

Recent studies on stress have paid close attention to the outcomes of global trends like the wars on terrorism. In this convulsed world of the 21st Century, civilians and military are exposed to a myriad of drawbacks, and everyone has to manage to carry out their lives and duties. The resulting work-related stress is present in a significant number of complaints in medical centers and hospitals; public, private or military. Although the United States Ready Reserve has not received much attention in the past, they are getting it now, given its more active interactions on foreign and domestic public policies. Hence, this research has sought to reflect upon the relationship between stress and supervisory styles in the reserve centers. This study reviewed and critiqued relevant empirical literature of the past two decades concerned with stress in the workplace. It also visited some historical publications on supervision and leadership styles affecting performances. In all, the results showed that the organizational culture is more related to stress than the supervisory styles in a naval reserve center.

Impact Of Mineral Levels On Soil pH And Non-leguminous Plants

Essential plant nutrients are necessary for plant growth, However, some of these nutrients are added as inorganic fertilizers due to high demand of food arising from fast growth in population which has necessitated the need to expand agricultural activities. This has lead to overuse of commercial inorganic fertilizers leading to drop in soil pH. Low pH reduces the availability of essential nutrients to plants and also low rate of decomposition of organic matter that is required to increase buffering capacity of the soil. Soil acidity is reduced by liming, which is an expensive exercise and does not add fertility to the soil. Leaves and leaf extracts of different plants have been suggested as an alternative to inorganic fertilizer and liming materials. However their efficacy has not been tested. The study, therefore, aimed at investigating the effect of growth rate of non-leguminous plants, including wheat (Triticum aestivum), kale (Brassica oleraceae var acephala) and coriander (Coriandrum sativum L)., grown on acidic soils treated with leaves and leaf extracts of plants known to have high buffering capacity and mineralisation.

Lands surfaces submitted to salt stress are increasing day by day in arid, semiarid regions and especially in the Mediterranean area. Nearly 40% of world's surface has salinity problems. At present, out of 1.5 billion hectares of cultivated land around the world, about 77 million hectares (5%) is affected by excess salt content. Salt stress is an abiotic stress that can affect the plant growth and physiological and biochemical activities such as photosynthesis activity and chlorophyll content. Decades of research have been devoted to understand the physiological mechanisms underlying the ability of plants to tolerate abiotic stress, in particularly, salinity and drought stresses. Ion distribution is one of different strategies commonly used by plants to improve salt stress tolerance. This book provides a physiological mechanism based upon various indices involved in cotton salt tolerance. Thereby, the book is recommended to all those who are interested in plant salt tolerance.

) To evaluate effects of various stress factors on immune response and growth performance of broiler chicks, a total of five experiments using 2000 broiler chicks were conducted. In each experiment, chicks were divided into five groups (A, B, C, D and E), and each group consisted of 80 day-old-chicks. In each experiment, the chicks were exposed to stress factors, such as temperature, stocking density, feed deprivation, water restriction and light. Each chick in groups A, B, C, and E was vaccinated against IBV, NDV, IBDV and HPSV, but chicks in group D were kept as unvaccinated controls. Blood samples from each group were collected on 36th day of age, at 18 hrs for determining TLC, DLC and H/L ratio. The antibody titers of chicks in different groups were analyzed using HI test at days 36th and 56th. The cellular response was analyzed by injecting PHA-P in the wattles of bird during post stress period. The effects of each stress on lymphoid organs were determined. The potential to resist virulent NDV challenge and effect of stress factors on body weight gains and FCR of chicks was also determined.

Defensive plant secondary metabolites against insects Defensive plant secondary metabolites against insects Новинка

Defensive plant secondary metabolites against insects

3549 руб.
Plants produce a broad range of secondary metabolites that are toxic to insect herbivores, either as part of their normal program of growth and development or in response to biotic stress (insect infestation). These secondary compounds that may act as signals, i.e. allelochemicals, mediating interactions between insects and plants. Secondary metabolites are present in all plants generally as mixtures that can be highly diverse. These mixtures have been shown to protect plants against insects; thus, secondary metabolite diversity has been suggested to be a resistance trait against plant consumers. Secondary metabolites are an extremely diverse group of natural products synthesized by plants. Most of secondary metabolites, such as terpenes, phenolic compounds and alkaloids are classified based on their biosynthetic origin.

Root specific expression of the GUS reporter gene was observed when transformed plants were grown fully inside solid media both under –P and +P and on MS media containing kanamycin. However, there was no GUS activity when plants were grown on the surface of the solid media and hydroponically under –P and +P conditions. Morphological root assessment for the knockout plants has shown no difference between the knockout genotypes and the wild type. Thus, contrary to previous result, in this study other stress than phosphorus deficiency factors were assumed to be contributing for the expression of the GUS reporter gene in all the constructs. Oxygen stress, mechanical impedance and stress due to the selective marker during seedling growth were thought to be possible reasons. However, since the effect of growing conditions was not evaluated before, this investigation needs further verification. Additionally, quantifying the GUS reporter gene activity in the transformant plants grown under - P and +P conditions by real time PCR helps to explore the real function of these genes.

Stress in Moroccan Arabic, and also in other languages, poses challenging problems for phonological theory. This is due to the fact that stress exhibits conflicting properties; which makes it difficult to provide answers to a number of issues. This book provides an investigation into a prominent aspect of prosodic phonology in Moroccan Arabic (a case study of the dialect of Rabat city), namely, stress assignment in the grammatical category of verbs within the framework of optimality theory as proposed in Prince and Smolensky and McCarthy and Prince. It particularly addresses a range of issues such as: the position of stress, the basis on which stress is located, the factors on the basis of which stress location is effected, the importance of the perceptual and the instrumental tests in shedding light on stress assignment, and the extent to which the optimality theoretic analysis confirm or disconfirm the results of the perceptual and the instrumental tests concerning stress placement. This book will be of interest to linguistics, teachers, researchers and to anyone interested in language study and phonological theory.
