摘要： The study aims to comprehensively characterize the BPC gene family in cotton at a genome-wide level and analyze their expression patterns through advanced computational methods, particularly emphasizing their involvement in conferring tolerance to salt stress. A total of 30 BPC genes were identified from three cotton species: Gossypium hirsutum (14 genes), Gossypium arboreum (8 genes), and Gossypium raimondii (8 genes). The genomic architecture, evolutionary relationships, and expression profiles of these genes were examined under various abiotic stresses. Bioinformatics tools mapped structural variations and evolutionary lineages, while heatmap and co-expression analyses identified genes with notable expression changes. This approach led to the identification of three potential candidate genes GH_D01G1605, GH_D13G0992, and GH_D02G1509—that exhibited notable variations in their expression in response to abiotic stress conditions, particularly salt stress. To further validate the findings, qRT-PCR was conducted, to confirm the expression of the GH_D01G1605 gene. Gene GH_D01G1605, which exhibited higher expression levels, was compared to the lower-expressed gene GH_A12G2243. Analysis revealed that GH_D01G1605 had a-2.6-fold greater expression than GH_A12G2243 and a-4.2-fold higher expression than the internal control, the actin gene. This research is the first detailed investigation of the BPC gene family in cotton, advancing our understanding of its role in abiotic stress tolerance. The findings highlight its potential in developing stress-resistant cotton cultivars, with important implications for agriculture and sustainability.
