Intensive investigations have been conducted on the effect of sole drought or salinity stress on the growth of plants. However, there is relatively little knowledge on how plants, particularly woody species, respond to a combination of these two stresses although these stresses can simultaneously occur in the field. In this study, mulberry, an economically important resource for traditional medicine, and the sole food of domesticated silkworms was subjected to a combination of salt and drought stress and analyzed by physiological methods and TMT-based proteomics. Stressed mulberry exhibited significant alteration in physiological parameters, including root/shoot ratio, chlorophyll fluorescence, total carbon, and ion reallocation. A total of 577 and 270 differentially expressed proteins (DEPs) were identified from the stressed leaves and roots, respectively. Through KEGG analysis, these DEPs were assigned to multiple pathways, including carbon metabolism, photosynthesis, redox, secondary metabolism, and hormone metabolism. Among these pathways, the sucrose related metabolic pathway was distinctly enriched in both stressed leaves and roots, indicating an important contribution in mulberry under stress condition. The results provide a comprehensive understanding of the adaptive mechanism of mulberry in response to salt and drought stress, which will facilitate further studies on innovations in terms of crop performance.

Garden roses do not grow well under hot and humid conditions. The objective of this study was to investigate the physiological responses of ‘Marie Curie’ and ‘Lapjau’ to high temperatures and relative humidity. The study included temperatures of 25/18°C (day/night) and 35/28°C (day/night), and relative humidity of 70% and 100%. ‘Marie Curie’ was more tolerant to heat stress than ‘Lapjau’ based on relative electrolyte leakage (REL), malondialdehyde (MDA), and activities of superoxide dismutase (SOD). The heat tolerance of cultivars also was confirmed by the levels of chlorophyll content and the net photosynthesis rate. Both cultivars were more stressed under more water vapour deficit than saturated vapour at 35/28°C (day/night), while at 25/18°C (day/night) the cultivars were more stressed under saturated humidity condition than at 70% relative humidity. In conclusion, combined hot and saturated humidity does not necessarily result in increased stress over separated heat or humidity elevations to the garden roses. Rose growers can use this information in regions where hot and humid conditions concur.

ABSTRACT: The cyclophilins genes are induced by abiotic stresses, yet their detailed function in drought and salinity remain largely unclear and need to be elaborately validated.Expression of cyclophilin was drastically induced under droughtconditions in Gossypiumherbaceum L. suggesting its stress-responsive function. In an attempt to characterize the role of G.herbacuemcyclophilingene GhCYP1, we overexpressed the GhCYP1 in tobaccousing Agrobacteriummediated transformationand explored its possible involvement in drought and salt stress tolerance.The transgenic plantsover expressing GhCYP1 exhibited tolerance against drought stress as evidenced by leaf disc assay, estimation of chlorophylland proline content along with various physiological parameters such as stomatal conductance, rate of photosynthesis and water use efficiency.The drought stressed transgenic tobaccoplants exhibited higher proline content in leaf ( 1.84 µ mol-g fw) and root (2.02µ mol-g fw ),while a reverse trend was observed in the drought stressed wild type plants, implicating the involvement of GhCYP1 in the maintenance of physiological homeostasis. Thedetail physiological, biochemical and molecular analysis results demonstrate the implicit role of GhCYP1 in conferring multiple abiotic stress tolerance at whole-plant level.

Polyamines are plant growth regulators, which take part in plant growth and development, as well as in the physiological responses to diverse biotic and abiotic stresses. Drought and waterlogging are environmental stress factors that disturb normal plant growth. In our study, we determined the content of polyamines spermine, spermidine, and putrescine in young wheat seedlings (Triticum aestivum L., cv. Sadovo-1) pretreated with herbicide Serrate® (Syngenta) and subjected for 7 days to drought or waterlogging. We found that when applied alone the herbicide caused some decrease in polyamine levels but it was not substantial as compared to drought and waterlogging stresses. Obvious reduction of polyamine content was caused by both stress factors when applied alone or in combination with the herbicide. The decrease was more significant in drought-stressed seedlings than in waterlogged. When plants were transferred to normal irrigation regime the polyamine concentrations in drought-stressed plants tended to increase. The waterlogging stress continued to reduce polyamine content even during the recovery period. These data correlate with the growth parameters (fresh weight, height of shoots) indicating the involvement of polyamines in the physiological responses of herbicide-primed wheat seedlings under stress conditions.

Trichoderma spp. are endophytic plant symbionts that are widely used as seed treatments to control diseases and to enhance plant growth and yield. Although some recent work has been published on their abilities to alleviate abiotic stresses, specific knowledge of mechanisms, abilities to control multiple plant stress factors, their effects on seed and seedlings is lacking. We examined the effects of seed treatment with T. harzianum strain T22 on germination of seed exposed to biotic stress (seed and seedling disease caused by Pythium ultimum) and abiotic stresses (osmotic, salinity, chilling, or heat stress). We also evaluated the ability of the beneficial fungus to overcome physiological stress (poor seed quality induced by seed aging). If seed were not under any of the stresses noted above, T22 generally had little effect upon seedling performance. However, under stress, treated seed germinated consistently faster and more uniformly than untreated seeds whether the stress was osmotic, salt, or suboptimal temperatures. The consistent response to varying stresses suggests a common mechanism through which the plant–fungus association enhances tolerance to a wide range of abiotic stresses as well as biotic stress. A common factor that negatively affects plants under these stress conditions is accumulation of toxic reactive oxygen species (ROS), and we tested the hypothesis that T22 reduced damages resulting from accumulation of ROS in stressed plants. Treatment of seeds reduced accumulation of lipid peroxides in seedlings under osmotic stress or in aged seeds. In addition, we showed that the effect of exogenous application of an antioxidant, glutathione, or application of T22, resulted in a similar positive effect on seed germination under osmotic stress or in aged seed. This evidence supports the model that T. harzianum strain T22 increases seedling vigor and ameliorates stress by inducing physiological protection in plants against oxidative damage.

Plants are constantly exposed to various stresses, which can degrade their health. The stresses can be alleviated by the application of methyl jasmonate (MeJA), which is a hormone involved in plant signalling. MeJA induces synthesis of defensive compounds and initiates the expression of pathogenesis-related genes involved in systemic acquired resistance and local resistance. Thus, MeJA may be used against pathogens, salt stress, drought stress, low temperature, heavy metal stress and toxicities of other elements. The application of MeJA improves growth, induces the accumulation of active compounds, and affects endogenous hormones levels, and other physiological and biochemical characteristics in stressed plants. Furthermore, MeJA antagonises the adverse effects of osmotic stress by regulating inorganic penetrating ions or organic penetrants to suppress the absorption of toxic ions. MeJA also mitigates oxidative stress by activating antioxidant systems to scavenge reactive oxygen species (ROS) in stressed plants. For these reasons, we reviewed the use of exogenous MeJA in alleviating biotic (pathogens and insects) and abiotic stresses in plants.

Ten grape rootstocks were subjected to moisture and salinity stress in two separate experiments. The influence of these stresses on gas exchange, water relation, and biochemical parameters was monitored at various stages of stress cycle. Both stresses indicated significant changes in the physiological and biochemical parameters studied. Some biochemical constituents increased by several folds in few rootstock cultivars which also recorded increased osmotic potential suggesting their role in osmotic adjustment. Some of the rootstock cultivars such as 110R, 1103P, 99R, Dogridge, and B2/56 recorded increased phenolic compounds under stressed conditions. The same rootstock also recorded increased water use efficiency. The increased accumulation of phenolic compounds in these cultivars may indicate the possible role of phenolic compounds as antioxidants for scavenging the reactive oxygen species generated during abiotic stresses thus maintaining normal physiological and biochemical process in leaves of resistant cultivars.

Shade trees are subjected to a wide variety of environmental stresses which decrease growth and cause injury and mortality. Although trees often are classed as either stressed or unstressed, all trees are periodically stressed by unfavorable environmental conditions above or below ground, and often both. Exposure of trees to some stresses also predispose them to the effects of other stresses. Healthy trees require adequate supplies and balances of carbohydrates, growth regulating hormones, water, and minerals. Environmental stresses, alone or in combination, reduce tree growth by setting in motion a series of complex physiological events leading to deficiencies of these essential substances. Explaining growth reduction of stressed trees by correlating growth with a single physiological process such as photosynthesis oversimplifies the causal events involved. Examples are given of some of the mechanisms by which drought, high and low temperature, mineral deficiency or excess, and environmental pollutants reduce growth and injure shade trees. Arborists can make important contributions in selecting appropriate species, adequately preparing planting sites, and imposing cultural practices that will minimize exposure of trees to stress factors.

The physiological response to application of elemental sulphur (S) and cadmium (Cd) of maize (Zea mays L.) grown for 60 days in pot soil was studied. The S was added into the soil with 2 rates (0 and 50 mmol/kg) and Cd was added in solution in 4 rates (0, 20, 50, 100 mg/kg). All the S and Cd were added before planting. Shoot biomass decreased with the application of Cd to the soil whether S was applied or not. The application of S and Cd to soil led to an increasing accumulation of Cd in the shoots of maize. The concentration of chlorophyll was reduced significantly in Cd-treated plants with or without supplementary S. The content of malondialdehyde (MDA) was increased significantly in treatments with S and Cd, compared to the control. The activity of peroxidases (POD) was increased but catalase (CAT) was decreased in plants treated with Cd, again with or without S, in comparison with control. POD and CAT activities decreased in all the Cd treated plants with S, as compared to the plants without S. The results suggest that Cd reduces the crop growth, concentration of chlorophyll and activity of CAT, but increases the content of MDA and activity of POD. S supplies decrease the content of MDA, activities of POD and CAT, as compared to zero S supplies at the same rate of Cd application.

Mestrado em Biologia Aplicada
Em Portugal, cerca de 700,000 ha foram já plantados com clones de Eucalyptus globulus, selecionados pelas suas elevadas taxas de crescimento, alta produção de polpa e adaptabilidade ambiental. Contudo, a produtividade das plantações de E. globulus tem enfrentado sérias limitações, principalmente devido à fraca disponibilidade de água. A seca é um importante stress abiótico que afeta negativamente o crescimento e o desenvolvimento das plantas, causando um conjunto de respostas fisiológicas, bioquímicas e moleculares. Embora esteja disponível um grande número de estudos que descreve as respostas das plantas ao stress hídrico, apenas alguns trabalhos se debruçam sobre os mecanismos que permitem a recuperação. Além disso, vários estudos descrevem também como diferentes genótipos podem diferir na capacidade de lidar com a seca. Considerando que manter a produção durante o stress hídrico não é o mais relevante, mas sim a capacidade de sobreviver e recuperar rapidamente após a re-hidratação, o objetivo deste estudo foi compreender os mecanismos envolvidos na recuperação, de modo a selecionar coleções clonais adequadas a plantações sustentáveis num clima mediterrânico. Com essa finalidade, dois clones de E. globulus (AL-18 e AL-126) foram submetidos a um período de três semanas em stress hídrico, seguido por uma semana de recuperação. Um perfil fisiológico foi obtido para cada genótipo, pela avaliação do crescimento, estado hídrico, peroxidação lipídica, respostas do aparelho fotossintético, trocas gasosas e concentração de ABA. Os principais resultados deste trabalho levam a concluir que: i) os genótipos escolhidos foram altamente tolerantes às condições testadas; ii) os clones selecionados apresentaram uma resposta similar na maioria dos parâmetros testados (exceto MDA, pigmentos, parâmetros fotossintéticos e ABA); iii) o clone AL-126 foi o mais resiliente à seca, mantendo taxas de crescimento mais elevadas em stress e após re-hidratação.
In Portugal, about 700,000 ha have been established with Eucalyptus globulus clones selected for their high growth rates, high pulp yield and environmental adaptability. However, productivity in E. globulus plantations has encountered serious limitations, mostly because of water availability. Drought is a major abiotic stress negatively affecting plant growth and development that causes an array of physiological, biochemical and molecular responses in plants. Apart from the great number of studies reporting on plant responses to drought stress and on the mechanisms to overcome stressful conditions, only a few reports providing evidence about the capacity of recovery and the underlying processes during recovery from drought are available. Moreover, ecophysiological studies have reported that different genotypes differ in their capacity to cope with drought. Considering that maintenance of production during drought is not the most important consideration, but rather the capacity to survive and recover rapidly after rewatering, the aim of this study was to understand the underlying mechanisms in recovery in order to select suitable clonal collections for sustainable plantations in a Mediterranean climate. For this propose, two E. globulus clones (AL-18 and AL-126) were subjected to a three-week water stress period, followed by one week recovery. A physiological profile was obtained for each genotype, assessing growth, water status, lipid peroxidation, photosynthetic responses, gas exchanges and ABA concentration. The main results of this work led us to conclude that: i) the chosen genotypes were highly tolerant to the conditions tested; ii) the selected clones presented a similar response in most of the tested parameters (except for MDA, pigments, fluorescence parameters and ABA); iii) clone AL-126 was the most resilient to drought, maintaining higher growth rates under stress and after rewatering.

Exposure of broiler cockerels to between 35.0 to 37.8 C for 24 hr at 5 days of age increases their survival when exposed to a heat challenge at 6 weeks of age (35.0-37.8 C; RH 50% ). This' phenomenon does not resemble acclimation since the physiological changes known to occur in acclimated birds exposed to heat have not been observed in the neonatally stressed birds. A series of experiments were conducted to elucidate the mechanisms of neonatally induced thermotolerance. In Experiment 1, the erythrocyte protein profile of control and 5 days heated birds prior to and during exposure to acute heat were determined. Prior to juvenile heat exposure no differences in the erythrocytic protein profile of neonatally stressed and control birds were observed at any age (10, 17, 24, 31 and 38 days of age) when maintained under control conditions. However, upon exposure to an acute heat challenge (40.5 C; 52 days of age) temporal and differential expressions of proteins similar in molecular weight to heat shock proteins (HSPs) were observed between the neonatally stressed and control birds. In Experiment 2, the effects of neonatal heat stress at various ages (5, 8, 12, 16 days of age) on the protein synthesis profile of heart, brain (telencephalon, diencephalon, brain stem, cerebellum) and liver tissues during exposure to an acute heat challenge were studied. In addition, body temperature during neonatal heat exposure was monitored. A significant increase in body temperature was observed during neonatal heat stress. A steady increase in the magnitude of the temperature change was noticed up to 12 days of age. Body temperature of birds exposed to neonatal heat at 16 days of age was similar to that of birds heated at 5 days of age.

During pregnancy, the basal activity is increased in both of our major stress response systems: the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. At the same time, the reactivity towards stressors is reduced. These alterations sustain maternal and fetal homeostasis, and are involved in the regulation of gestational length. Although the feto-placental hormone synthesis produces the main endocrinological changes, also the central nervous system undergoes adaptation. Together, these profound adjustments have been suggested to make women’s mental health more vulnerable during pregnancy and postpartum period. The aim of this thesis was to examine factors connected to physiological stress responses during the late pregnancy in relation to pain, labour onset, emotional reactivity, and mental health. The first study examined the pain and sympathetic response during cold stress, in relation to time to delivery. Women with fewer days to spontaneous delivery had lower sympathetic reactivity, while no pain measure was associated with time to delivery. In the second study, acoustic startle response modulation was employed to study emotional reactivity during late gestation, and at four to six weeks postpartum. The startle response was measured by eye-blink electromyography, while the participants watched pleasant and unpleasant pictures, and positive and negative anticipation stimuli. A significant reduction in startle modulation by anticipation was found during the postpartum assessment. However, no startle modulation by pleasant, or unpleasant, pictures was detected at either time-point. The serum level of allopregnanolone, a neurosteroid implied in pregnancy-induced hyporeactivity, was analysed in relation to self-reported symptoms of anxiety and depression. Although the participants reported low levels of depression, the women with the highest depression scores had significantly lower levels of serum allopregnanolone. There was no correlation between allopregnanolone and anxiety scores. In the fourth study, the cortisol awakening response was compared between women with depression during pregnancy, women with depression prior to pregnancy, and women who had never suffered from depression. No group differences in cortisol awakening response during late pregnancy were found. The results are in line with the previously described pregnancy-induced hyporesponsiveness, and add to the knowledge on maternal stress hyporeactivity, gestational length, and maternal mental health.

This thesis aimed to increase understanding of the underlying physiological sources of the substantial inter-individual variability in heart rate (HR) and blood pressure (BP) reactions to acute psychological stress. This aim was achieved using a multi-method approach that included meta-analysis, laboratory studies, and prospective secondary analysis of epidemiological data. Chapter 2 implicated beta-adrenergic sympathetic activation and parasympathetic withdrawal in the cardiovascular stress response and showed that autonomic changes vary as a function of stress task, age, and sex. Chapter 3 demonstrated that individual differences in a unique HR complexity marker accounted for a significant amount of the observed variance in HR reactivity and that this effect was independent of task performance and changes in autonomic activity and respiration. Chapter 4 revealed that individual differences in resting physiological allostatic load related to HR reactivity such that higher allostatic load indicated lower reactivity. Finally, in Chapter 5, multivariate cluster analysis of HR, systolic and diastolic BP reactivity resolved a large sample into four homogenous clusters, each displaying significantly different reactivity patterns and risk of hypertension at 5-year follow-up. The research reported in this thesis confirms already suspected physiological sources of individual difference but also reveals novel sources that deserve further inquiry.

Because of the impact of stress on health, it is important to understand the variables that underlie cardiovascular reactivity to stress because it may lead to more focused targets of intervention for helping people to reduce or otherwise better manage their stress. The purpose of the present study was to answer the following questions: does lack of eudaimonic well-being (a combination of psychological and social well-being) predict increased cardiovascular reactivity to stress in a clinically distressed population? And does increased eudaimonic well-being protect against increased cardiovascular reactivity to stress when hedonic well-being (a combination of positive affect and life satisfaction) is low and depression and stress are high? If so, then it may be possible to reduce the effects of stress on health even if depression and stress are present. One hundred twenty-nine college students (ages 18-29) who were clinically distressed were administered a questionnaire that included questions about demographic variables and measures of hedonic and eudaimonic well-being, depression, and general perceived stress. After answering the questionnaire, a baseline reading of cardiovascular activity was taken. After the baseline reading, participants were subjected to the Trier Social Stress Test (TSST), an interpersonal stressor that consists of an anticipation period, a speech, and a math task. Measurements of cardiovascular activity were taken throughout the TSST. I predicted that lower levels of eudaimonic and hedonic well-being, mental health, and higher amounts of general perceived stress would predict increased cardiovascular reactivity to the TSST as measured by systolic blood pressure, diastolic blood pressure, and heart rate. Then, should the prior hypothesis be true, I predicted that higher eudaimonic well-being will suppress the effect of lower hedonic will-being, lower mental health, and higher general perceived stress on cardiovascular activity to acute stress. Results of the study found no effect of eudaimonic well-being, hedonic well-being, depression, and general perceived stress on cardiovascular reactivity during the TSST. The results suggest that there is no relationship between well-being, depression, and general perceived stress and cardiovascular reactivity to stress in a young college student population.

AbstractDuring military training and operations, exposure to extremes of noise, temperature, humidity, pressure, or acceleration can induce levels of physiological strain that degrade cognitive and physical capabilities, threaten health and safety, and affect behavior and performance. The overarching purpose of this chapter is to discuss the impact of environmental stress on military personnel. Because each of the aforementioned stressors induces disparate effects, each section addresses a unique stressor in terms of (i) the nature of the threat, (ii) physiological and biomedical effects, (iii) the impact on performance, and (iv) management strategies. The evolution of next-generation wearable biosensors, smart performance algorithms, and scientifically based operational training methods including stress inoculation exposure that will contribute to improved training, adaptation, and tolerance to these operational stresses is discussed.

AbstractSalinity is a major abiotic stress which decreases crop productivity. Salt stress also causes osmotic, water, ionic and oxidative stresses. Plants exposure to salt can check their growth by reduction in water and nutrient uptake, osmotic imbalance and cytotoxicity incited by sodium and chloride ions. Present study deals with the impact of salt on germination, growth and physiological components of fenugreek and its alleviation by the application of calcium silicate. The salt stress reduced fenugreek germination and growth but supplementation of calcium silicate to salt stressed seedlings mitigated deleterious impacts of salinity. Various parameters like germination, seedling length, biomass, pigment and protein contents of fenugreek seedlings were significantly improved with calcium silicate under salt stress. Maximum reduction 53.3% in protein amount was recorded in fenugreek seedlings treated with NaCl (10 mM) over control. Significant increase in total antioxidant content in fenugreek seedlings was observed with calcium silicate as it showed the following order: Ca2SiO4 > NaCl + Ca2SiO4 > NaCl > Control. Hence, application of calcium silicate can be useful for the fenugreek plants growing under saline conditions.

Drought and other abiotic stresses have major negative effects on agricultural productivity. The plant hormone abscisic acid (ABA) regulates many responses to environmental stresses and can be used to improve crop performance under stress. ABA levels rise in response to diverse abiotic stresses to coordinate physiological and metabolic responses that help plants survive stressful environments. In all land plants, ABA receptors are responsible for initiating a signaling cascade that leads to stomata closure, growth arrest and large-scale changes in transcript levels required for stress tolerance. We wanted to test the meaning of root derived ABA signaling in drying soil on water balance. To this end we generated transgenic tomato lines in which ABA signaling is initiated by a synthetic agonist- mandipropamid. Initial study using a Series of grafting experiments indicate that that root ABA signaling has no effect on the immediate regulation of stomata aperture. Once concluded, these experiments will enable us to systematically dissect the physiological role of root-shoot interaction in maintaining the water balance in plants and provide new tools for targeted improvement of abiotic stress tolerance in crop plants.

Stress is a multidimensional construct that comprises exposure to events, perceptions of stress, and physiological responses to stress. Research consistently demonstrates a strong association between stress and a myriad of physical and mental health concerns, resulting in a pervasive and interdisciplinary agreement on the importance of investigating the relationship between stress and health. Developing a holistic understanding of stress requires assessment of the three domains vital to the study of stress: (1) the presence of environmental stressors, (2) psychological and biological reactions to stressors, and (3) the length of time over which the stressor or stress response occurs. Research into all three domains requires multiple methods. Self-reports allow for subjective evaluations of stress that illuminate the duration and severity of the psychological response to stressors. Biomarkers, in turn, capture a more-objective measure of stress and create a deeper understanding of the biological response to chronic and acute stress. Finally, the use of digital biomarkers allows for further exploration of the physiological fluctuations caused by stress by measuring the changes occurring at the same time as the stressor. Future research on stress and health should favor a multidimensional approach that creates a triangulated picture of stress, drawing from each of the three aforementioned method groups.
