In this study, 16 maize (<i>Zea mays</i>) <i>NF-YA</i> subunit genes were identified using bioinformatics methods, and they were divided into three categories by a phylogenetic analysis. A conserved domain analysis showed that most contained a CCAAT-binding transcription factor (CBFB) _NF-YA domain. Maize <i>NF-YA</i> subunit genes showed very obvious tissue expression characteristics. The expression level of the <i>NF-YA</i> subunit genes significantly changed under different abiotic stresses, including <i>Fusarium graminearum</i> infectioPeerJe14306https://www.ebi.ac.uk/biostudies/studies/S-EPMC9648346biostudies-literatureIdentification and expression analysis of maize <i>NF-YA</i> subunit genes.PMC9648346Xing JLv MCao HZhang KZang JDong JSi HWang XfalseIdentification and expression analysis of maize <i>NF-YA</i> subunit genes.<i>NF-YAs</i> encode subunits of the nuclear factor-Y (NF-Y) gene family. <i>NF-YA</i>s represent a kind of conservative transcription factor in plants and are involved in plant growth and development, as well as resistance to biotic and abiotic stress.
