摘要： Plant Carbonic anhydrases (Cas) have been shown to be stress-responsive enzymes that may play a role in adapting to adverse conditions. Cotton is a significant economic crop in China, with upland cotton (Gossypium hirsutum) being the most widely cultivated species. We conducted genome-wide identification of the beta CA gene in six cotton species and preliminary analysis of the beta CA gene in upland cotton. In total, 73 beta CA genes from six cotton species were identified, with phylogenetic analysis dividing them into five subgroups. GH beta CA proteins were predominantly localized in the chloroplast and cytoplasm. The genes exhibited conserved motifs, with motifs 1, 2, and 3 being prominent. GH beta CA genes were unevenly distributed across chromosomes and were associated with stress-responsive cis-regulatory elements, including those responding to light, MeJA, salicylic acid, abscisic acid, cell cycle regulation, and defence/stress. Expression analysis indicated that GH beta CA6, GH beta CA7, GH beta CA10, GH beta CA15, and GH beta CA16 were highly expressed under various abiotic stress conditions, whereas GH beta CA3, GH beta CA9, GH beta CA10, and GH beta CA18 had higher expression patterns under Verticillium dahliae infection at different time intervals. In Gossypium thurberi, Gth beta CA1, Gth beta CA2, and Gth beta CA4 showed elevated expression across stress conditions and tissues. Silencing GH beta CA10 through VIGS increased Verticillium wilt severity and reduced lignin deposition compared to non-silenced plants. GH beta CA10 is crucial for cotton's defense against Verticillium dahliae. Further research is needed to understand the underlying mechanisms and develop strategies to enhance resistance against Verticillium wilt.
