Evolution of the Response to Heat Shock in Genus Drosophila

Evolution of the Response to Heat Shock in Genus Drosophila Thermotolerance was studied in a wide spectrum of Drosophilaspecies and strains originating from different climatic zones and considerably differing from one another in the ambient temperature of their habitats. The species that lived in hot climate have a higher thermotolerance. Most species of the virilisgroup exhibited positive correlation between the HSP70 accumulation after heat exposure and thermotolerance; however, this correlation was absent in some species and strains. For example, the D. melanogasterOregon R strain, which had the highest sensitivity to heat shock (HS) among all strains and species studied, displayed the maximum level of HSP70 proteins after HS. The patterns of induction of various heat shock protein (HSP) families after heat exposure in a wide spectrum of Drosophila species were compared. The results obtained suggest that the HSP40 and low-molecular-weight HSPs (lmwHSPs) play a significant role in thermotolerance and adaptation to hot climate. Polymorphism in hsp70 gene clusters ofDrosophila and variation in the numbers of gene copies andhsp70 isoforms in group viriliswere found. The evolutionary role of the variation in the number of hsp70 gene copies observed in the strains and species of genusDrosophilais discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals
