Genome‑wide identification of the cotton FAR gene family reveals GhFAR3 as a positive regulator of Verticillium dahliae resistance.

ABSTRACT: Although fatty acyl-CoA reductase (FAR) proteins are known to play essential roles in plant growth and development, their involvement in biotic and abiotic stress responses remains insufficiently characterized. In this study, we performed a comprehensive genome-wide analysis of 31 FAR genes across four cotton species (Gossypium arboreum, G. raimondii, G. hirsutum, and G. barbadense). Phylogenetic and synteny analyses classified these FAR genes into three distinct clades, with whole-genome duplication events contributing significantly to their expansion. Promoter cis-element analysis and transcriptome profiling revealed that while most FAR genes were downregulated under abiotic stress, many were notably upregulated in response to hormone treatments and Verticillium dahliae infection.
