The NF-Y gene family plays an important role in plant growth, development, and stress responses. This study identified 64 members of the NF-Y gene family in the Medicago sativa genome and found that these genes were significantly induced or downregulated by alkali treatment. These findings provide a basis for further research on the function of NF-Y genes in Medicago sativa and other legume species.
The nuclear factor Y (NF-Y) gene family is an important transcription factor family consisting of three subfamilies, NF-YA, NF-YB and NF-YC, which are widely involved in plant growth and development, stress responses and other processes. In this study, we identified 64 members of the NF-Y gene family in the M. sativa L. (Xinjiang Daye) genome, including 11 MsNF-YAs, 33 MsNF-YBs and 20 MsNF-YCs. Analysis of conserved motifs indicated that each unit included unique compounds of motifs, although certain members lost some motifs. Conserved functional domain analysis showed that each subunit contained a specific set of functional domains. Analysis of cis-acting elements in the promoter region of the MsNF-Y genes identified a series of cis-acting elements associated with stress responses. In addition, the transcriptome data and qRT-PCR analysis showed that MsNF-Y genes were significantly induced or downregulated by alkali treatment. The results of this study may help to establish a basis for further cloning and functional studies of NF-Y genes in Medicago sativa and other related legume species.
