CaNAC76 enhances lignin content and cold resistance in pepper by regulating CaCAD1.

Low temperature restricts the growth, development, and yield of peppers, significantly limiting the development of the pepper industry. NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) are implicated in plant responses to cold stress, but their specific mechanisms in peppers are unclear. In this study, we isolated a cold-induced NAC transcription factor, CaNAC76, from pepper (Capsicum annuum L.

ERD14 regulation by the HY5- or HY5-MED2 module mediates the cold signal transduction of asparagus bean.

Cold stress affects the growth, development, and yield of asparagus bean (Vigna unguiculata subsp. sesquipedalis). Mediator (MED) complex subunits regulate the cold tolerance of asparagus bean, but the underlying regulatory mechanisms remain unclear.
