Insights into the Role of <i>GhTAT2</i> Genes in Tyrosine Metabolism and Drought Stress Tolerance in Cotton.

ABSTRACT: Gossypium hirsutum is a key fiber crop that is sensitive to environmental factors, particularly drought stress, which can reduce boll size, increase flower shedding, and impair photosynthesis. The aminotransferase (AT) gene is essential for abiotic stress tolerance. A total of 3 Gossypium species were analyzed via genome-wide analysis, and the results unveiled 103 genes in G. hirsutum, 47 in G. arboreum, and 53 in G. raimondii. Phylogenetic analysis, gene structure examination, motif analysis, subcellular localization prediction, and promoter analysis revealed that the GhAT genes can be classified into five main categories and play key roles in abiotic stress tolerance. Using RNA-seq expression and KEGG enrichment analysis of GhTAT2, a coexp
