Heritability of Expression of the 70kd Heat-shock Protein in Drosophila Melanogaster and Its Relevance to the Evolution of Thermotolerance.
The principle inducible heat-shock protein of Drosophila melanogaster, Hsp70, contributes to thermotolerance throughout the entire life cycle of the species but may also reduce fitness in some life stages. In principle, selection might maximize the benefits of Hsp70 expression relative to its costs by adjusting the magnitude of Hsp70 expression for each life-cycle stage independently. Therefore...
متن کاملEvolution of thermotolerance and the heat-shock response: evidence from inter/intraspecific comparison and interspecific hybridization in the virilis species group of Drosophila. I. Thermal phenotype.
Species in the virilis group of Drosophila (fruit flies), which overlap or replace one another along climatic gradients, exhibit corresponding differences in basal thermotolerance, inducible thermotolerance and the heat-shock response. The low-latitude species D. virilis exceeds the high-latitude species D. lummei in these measures of thermotolerance, the temperature threshold for heat-shock fa...
متن کاملGenetic variation in heat resistance and HSP70 expression in inbred isofemale lines of the springtail Orchesella cincta
The functional relationship between thermotolerance and heat shock protein (HSP) expression is well described. However, the intraspecific variation in HSP70 expression and heat resistance is not fully understood. Some studies have shown a correlation between thermotolerance and HSP70 expression levels at the intraspecific level, whereas others have not, and results depend on species, developmen...
متن کاملEvolvability of Hsp70 expression under artificial election for inducible thermotolerance in independent populations of Drosophila melanogaster.
To test whether expression of the inducible heat-shock protein Hsp70 increases under selection for inducible thermotolerance in Drosophila melanogaster, we performed artificial selection on replicate sets of Drosophila lines founded from two independent populations. Selection entailed pretreatment at 36 degrees C to induce thermotolerance and Hsp70 expression, followed by a more severe heat sho...
متن کاملVariation in heat-shock proteins among species of desert fishes (Poeciliidae, Poeciliopsis).
Analysis of the heat-shock proteins (hsps) of six closely related species of Poeciliopsis demonstrated the existence of biochemical diversity in the hsp100, hsp70, hsp60, and hsp30 protein families among species. Each species expressed five to seven hsp70-related isoforms. Constitutive 70-kD isoforms were identical among species, but four different patterns of heat-inducible isoforms were seen ...
