摘要: Fruit ripening is a complex process involving physiological and metabolic changes that influence fruit color, flavor, aroma, and texture, which is modulated by various hormones and key genes. NAC with transmembrane motif-like (NTL) transcription factors belong to the NAC gene family with transmembrane motifs at their Cterminus and play important roles in plant growth, development, and stress responses. However, the role of NTL during fruit ripening remains enigmatic. Here, we identified a NTL gene, MaNAC169, that was regulated by ethylene during banana fruit ripening. MaNAC169 contained a conserved TM in its far C-terminal region and localized in the nucleus and plasma membrane. Its active form, MaNAC169-Delta C4, acted as a transcriptional activator. Importantly, MaNAC169 directly bound to the promoters of MaACO1, MaEXP2, MaXET1, and MaGWD1 and positively regulated their gene expression. MaNAC169 also activated its own expression and could form a dimer with itself. Moreover, transient MaNAC169-Delta C4 overexpression in banana fruit promoted ripening by inducing target gene expression. Taken together, MaNAC169 positively modulated fruit ripening by activating the expression of ripening-associated genes. Our findings provide new insights into the transcriptional regulatory mechanisms involved in fruit ripening.
