A proposed model for the transcriptional cascade function of MaMADS1–MaNAC083 in ethylene biosynthesis throughout banana ripening. MaMADS1 binds the MaNAC083 promoter and represses its expression, which attenuates the MaNAC083-mediated repression of MaACS1, MaACO1, MaACO4, MaACO5, and MaACO8, and eventually promotes ethylene biosynthesis.
