Analysis of experimental populations of Drosophila has shown different selective value of S- and F-alleles of Adh locus under selection for delayed aging, resistance to elevated temperature and ethanol. Selection for delayed aging and resistance to hyperthermia was accompanied by an increase of Adhs frequency in populations and genotypic adaptation to ethanol- by an increase of AdhF frequency.

Background: HCV genotypes are 30-35% polymorphic at the nucleotide level, while subtypes within the same genotype differ by nearly 20%. Although previous studies have shown the immune escape potential of several mutations within the HCV proteins, little is known about the effect of genotype/subtype-specific gene polymorphism on T-cell immunity. Therefore, this study employed several methods to examine the impact of genotype/subtype-specific polymorphisms in Core, NS3, NS5A, and NS5B sequences on T cell epitope processing and HLA-epitope interactions.

Cotton is essential for the global textile industry however, climate change, especially extreme temperatures, threatens sustainable cotton production. This research aims to identify breeding strategies to improve heat tolerance and utilize stress-resistant traits in cotton cultivars. This study investigated heat tolerance for 50 cotton genotypes at the seedling stage by examining various traits at three temperatures (32 °C, 45 °C and 48 °C) in a randomized plot experiment.

With climate change projections indicating an increase in the frequency of extreme heat events and irregular rainfall patterns globally, the threat to global food security looms large. Terminal heat stress, which occurs during the critical reproductive stage, significantly limits lentil productivity. Therefore, there is an urgent need to improve lentil's resilience to heat stress to sustain production.

Calligonum polygonoides, an endangered species of desert due to poor regeneration and overexploitation, which requires immediate conservation attention. Genetic diversity analysis is crucial for effective conservation and management initiatives, for elite genotypes. Therefore, in the present study, SCoT (start codon target) and ISSR (inter simple sequence repeat) markers were used to investigate the genetic variability in 120 individuals of Calligonum polygonoides.
