Characterization and gene expression analysis reveal universal stress proteins respond to abiotic stress in Gossypium hirsutum.

ABSTRACT:

Background

Universal stress proteins (USPs) are a class of stress-induced proteins that play a crucial role in biotic and abiotic stress responses. These proteins have previously been reported to participate directly in responses to various stress and protect plants against unfavorable environmental conditions. However, there is limited research on USPs in cotton, and systematic characterization of USPs in Gossypium species is lacking.

Results

In the present study, the USP genes in Gossypium hirsutum were systematically identified and classified into six distinct subfamilies. The expansion of USPs in Gossypium species is mainly caused by dispersed duplication and whole genome duplication. Notably, the USPs that have expanded through allotetraploidization events are highly co
