Effects of Nitrate and Cytokinin on Nitrogen Metabolism and Heat Stress Tolerance of Creeping Bentgrass
… impacts of N and CK on creeping bentgrass under heat stress; 3) to investigate the simultaneous effects of CK and N on the antioxidant responses of heat stressed creeping bentgrass; and 4) to examine the expression pattern of the major heat shock proteins (HSPs) in creeping bentgrass during …

Study of Thermotolerance Mechanism in Gossypium Hirsutum Through Identification of Heat Stress Genes
<p>ABSTRACT</p> <p>Heat stress causes major losses to cotton seed and lint yield. Introduction of heat stress tolerance to Arkansas cotton varieties is highly desirable. However, very little is known about the molecular basis of heat stress tolerance in cotton. The present study attempted to …

GENETIC PARAMETERS FOR HEAT AND SALINITY STRESS TOLERANCE IN NORTHERN GULF OF MEXICO EASTERN OYSTER, CRASSOSTREA VIRGINICA
… In this study, the feasibility of improving tolerance to these two stresses by selection was evaluated in common garden experiments employing a pool of 160 families. Heat stress tolerance was evaluated in seed (3.5 months) and adults (14 months) by applying a sustained temperature of 38-39 °C …

Ploidy and Ecophysiology analysis of the Arenaria ciliata L. complex (Caryophyllaceae) in Europe
… fluorescence analysis illustrated that cold stress tolerance capacity in each ecotype is more closely associated with the climate of the home population site than with evolutionary lineage, showing that cold stress tolerance capacity is greatest in the ecotypes of A. bernensis (Swiss Alps) …

Physiological and Metabolic Responses to Water-deficit and Heat Stress of Virginia-type Peanut Cultivars and Breeding Lines
… In recent years, an increased frequency of heat and drought episodes with significant effects on peanut yield was observed in the VC region. Because limited information is available on the mechanisms virginia-type peanut develops in response to heat and water stress, the present study …

Morpho-Physiological responses of spring wheat(Triticum Aestivum L.) to heat stress
Constant or transitory high temperatures affect wheat growth and development leading to diverse morphological, physiological and biochemical changes that eventually decrease grain yield. It is against this background that this study was conducted to identify morpho-physiological traits associated …

Biological Consequences of Atypical Phage Conversion in Gram-Positive Pathogens
… alter expression of htrA2 and promote increased heat-stress tolerance. This work suggests that for S. aureus, in addition to carrying important virulence determinants, phage may also play a rather widespread role as DNA-level switches to control virulence factor expression and/or generate …

Analysis of the relationship between genomic instability, heterozygosity levels and phenotype in Saccharomyces cerevisiae
… two important industrial traits of this strain – heat stress tolerance and growth kinetics. We identified several genomic regions potentially associated with those traits and conducted experiments to investigate the bulk contributions of heterozygosity blocks in three specific chromosomes. This …

Plant growth, stress tolerant traits and regulation of heat activated proteins in Aspalathus linearis (Burm. f.) R. Dahlgren exposed to elevated temperature and drought
… and nights as well as an increased occurrence of heat waves, and drought periods globally. The Intergovernmental Panel on Climate Change has stated that global surface temperatures are constantly increasing and are likely to exceed 2 °C, compared to average temperatures in 1900, by the end of the …
