Background: Nuclear factor Y (NF-Y) plays a vital role in numerous biological processes as well as responses to biotic and abiotic stresses. However, its function in ginger (Zingiber officinale Roscoe), a significant medicinal and dietary vegetable, remains largely unexplored. Although the NF-Y family has been thoroughly identified in many plant species, and the function of individual NF-Y TFs has been characterized, there is a paucity of knowledge concerning this family in ginger.
Methods: We identified the largest number of NF-Y genes in the ginger genome using two BLASTP methods as part of our ginger genome research project. The conserved motifs of NF-Y proteins were analyzed through this process. To examine gene duplication events, we employed the Multiple Collinearity Scan toolkit (MCScanX). Syntenic relationships of NF-Y genes were mapped using the Dual Synteny Plotter software. Multiple sequence alignments were performed with MUSCLE under default parameters, and the resulting alignments were used to generate a maximum likelihood (ML) phylogenetic tree with the MEGA X program. RNA-seq analysis was conducted on collected samples, and statistical analyses were performed using Sigma Plot v14.0 (SYSTAT Software, USA).
Results: In this study, the ginger genome was utilized to identify 36 NF-Y genes (10 ZoNF-YAs, 16 ZoNF-YBs, and 10 ZoNF-YCs), which were renamed based on their chromosomal distribution. Ten distinct motifs were identified within the ZoNF-Y genes, with certain unique motifs being vital for gene function. By analyzing their chromosomal location, gene structure, conserved protein motifs, and gene duplication events, we gained a deeper understanding of the evolutionary characteristics of these ZoNF-Y genes. Detailed analysis of ZoNF-Y gene expression patterns across various tissues, performed through RNA-seq and qRT-PCR, revealed their significant role in regulating ginger rhizome and flower growth and development. Additionally, we identified the ZoNF-Y family genes that responded to abiotic stresses.
Conclusion: This study represents the first identification of the ZoNF-Y family in ginger. Our findings contribute to research on evolutionary characteristics and provide a better understanding of the molecular basis for development and abiotic stress response. Furthermore, it lays the foundation for further functional characterization of ZoNF-Y genes with an aim of ginger crop improvement.
