Genome-wide analysis of the DnaJ gene family and their expression profiles under salt stress in potato.

ABSTRACT:

Background

Saline stress is one of the primary environmental factors affecting global food security, significantly jeopardizing crop quality and yield. DnaJ proteins (DnaJs) are a type of protein that plays an important role in dealing with salt stress for plants. Nevertheless, the comprehensive exploration of the DnaJ gene family and its role in salt stress in potato (Solanum tuberosum L.) is rare.

Results

A total of 113 StDnaJs were identified from the potato genome, and they were categorized into three distinct types, with the same type members possessing similar structures. Gene duplication analysis identified twenty-five pairs of duplicated genes, potentially contributing to the expansion of the StDnaJ family in potato. The promoters of StDnaJ genes contained numerous c
