Gene and transposable element expression in response to stress in temperate and tropical populations of Drosophila.

ABSTRACT:

Background

The study of stress response in natural populations is crucial for understanding species local adaptation and evolution. In Drosophila, significant genetic diversity across populations from different geographical origins has been observed, emphasizing the influence of local environments.

Results

In this study, we explored the impact of starvation and cold stress on the phenotypic and transcriptomic response of two natural populations of D. melanogaster and D. simulans from temperate and tropical regions. Additionally, we investigated the behavior and influence of transposable elements (TEs) in these types of stress, combining RNA-seq and ChIP-seq experiments, with high-quality long-read genome assemblies of all the strains. Our findings in D. melanogaster revealed
