| Abstract: | NF-Y (nuclear factor-Y) family genes play an important role in plant growth, development and response to stress. Related studies on NF-YC subunit genes of maize have not been reported. In this study, 17 NF-YC subunit genes in silicon cloning and bioinformatics methods were divided into three subfamilies, encoding product of CBFD_NFYB_HMF domain by conserved domain analysis. During maize different developmental stages and different tissues, NF-YC subunit genes exhibited significantly different expression levels. The maize NF-YC subunit genes were detected with obvious differences in their expression level under different abiotic stresses and Fusarium Verticillioide infection. Based on qRT-PCR results, the expression levels of NF-YC subunit genes were significantly changed after SA, JA and ET hormones treatments. Collectively, NF-YC subunit genes display conserved functions in maize growth and development as well as resistance to abiotic and biotic stresses, laying a foundation for elucidating the mechanism of NF-YC subunit genes in maize. |
