Yeast cells respond to stress by mediating condition-specific gene expression changes and by mounting a common response to many stresses, called the environmental stress response (ESR). Giaever et al. previously revealed poor correlation between genes whose expression changes in response to acute stress and genes required to survive that stress, raising question about the role of stress-activat...

introduction safflower is native to iran, and is cultivated for high adaptability, low water requirement, resistance to drought and useful unsaturated fatty acid (ashri et al., 1977). identification of effective agronomic traits and relationship between them are important aims under water stress conditions. among these characters, grain yield is the most important trait that is genetically poly...

Abstract To study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. Analysis of variance showed considerable variation among cultivars. Water stress reduced all of the studied morphological characteristics, espe...

Abstract Five bread wheat (Triticum aestivum L.) cultivars including Kavir, Pishtaz, Niknejad, Omid and Roshan were evaluated in a split plot experiment based on randomized complete block design with three replications. Water stress and well-watered conditions were assigned to the main plots and varieties to the subplots. Water stress was imposed by withholding irrigation at the booting stage....

in order to evaluate the effect of terminal water deficit stress on leaf traits and their relations to grain yield in different barley genotypes (‘yousof’, ‘fajr30’, ‘nosrat’, ‘pbyt-46’, ‘pbyt-97’ and ‘morocco’), two separated experiments were conducted in stress (water withholding from anthesis towards the end of growing season), and non stress (normal irrigation) conditions based on rcbd with...

drought stress is considered as the most important environmental abiotic stress, affecting grain yield of crop plants especially in arid and semi arid regions. increasing and utilization of the genetic diversity can be a useful strategy in breeding for drought resistance. in this study, twenty iranian durum wheat landraces along with two check cultivars were evaluated in a randomized complete b...

In this paper we prove a Hölder and Lipschitz stability estimates of determining all coefficients of a dynamical Lamé system with residual stress, including the density, Lamé parameters, and the residual stress, by three pairs of observations from the whole boundary or from a part of it. These estimates imply first uniqueness results for determination of all parameters in the residual stress sy...

ackground: Stress, one of the strongest risk factors for depression, has been linked to “anhedonic” behavior and dysfunctional eward-related neural circuitry in preclinical models. ethods: To test if acute stress reduces reward responsiveness (i.e., the ability to modulate behavior as a function of past reward), a ignal-detection task coupled with a differential reinforcement schedule was utili...
