ABSTRACT
Flowering Chinese cabbage (Brassica campestris L. ssp. Chinensis var. utilis Tsen et Lee) is a widely consumed vegetable in southern China with significant economic value. Developing product organs in the flowering Chinese cabbage involves two key processes bolting and flowering. Nuclear factor Y (NF-Y) is a heterotrimeric transcription factor known for its crucial role in various plant developmental processes. However, there is limited information available on the involvement of this gene family during flowering during Chinese cabbage development. In this study, 49 BcNF-Y genes were identified and characterized along with their physicochemical properties, gene structure, chromosomal location, collinearity, and expression patterns. We also conducted subcellular localization, yeast two-hybrid, and transcriptional activity assays on selected BcNF-Y genes. The findings of this study revealed enhanced expression levels of specific BcNF-Y genes during the stalk development and flowering stages in flowering Chinese cabbage. Notably, BcNF-YA8, BcNF-YB14, BcNF-YB20, and BcNF-YC5 interacted with BcRGA1, a negative regulator of GA signaling, indicating their potential involvement in GA-mediated stalk development. This study provides valuable insights into the role of BcNF-Y genes in flowering Chinese cabbage development and suggests that they are potential candidates for further investigating the key regulators of cabbage bolting and flowering.
