摘要： Background Nuclear transcription factor Y subunit A (NFYA) plays an important role in plant growth, development, and response to abiotic stress. Results This study systematically analyzed the NFYA gene family. Chromosome location analysis found that some NFYA genes in Gossypium hirsutum may have been lost during evolution. Collinearity analysis and selection pressure analysis indicated that the GhNFYA gene family underwent fragment duplication and whole genome duplication during evolution. At the same time, promoter cis-element analysis and gene interaction network analysis predicted that the expression of GhNFYA gene may be regulated by plant hormones and stress. To further explore the function of the gene, Gossypium hirsutum seedlings were treated with 4 degrees C, 37 degrees C, salt and PEG stress, respectively, found that the expression of NFYA is stimulated by multiple environments. By constructing a co-expression network, interactions between genes were found to defend against salt stress. Through virus-induced gene silencing experiments, it was found that plants that silenced the GhNFYA16 gene were significantly more sensitive to salt stress. Conclusions This study found the relationship between the structure and function of NFYA gene family, provided a basis for the biological identification and functional verification of NFYA family members, and provided clues to clarify the specific roles of different types of NFYA proteins under different abiotic stress.
