MdNAC4 Interacts With MdAPRR2 to Regulate Nitrogen Deficiency-Induced Leaf Senescence in Apple (Malus domestica)
Nitrogen (N) is one of the important macronutrients in plants, and N deficiency induces leaf senescence.However, the molecular mechanism underlying how N deficiency affects leaf senescence is unclear.Here, we report an apple NAC TF, MdNAC4, that participates in N deficiency-induced leaf senescence.The senescence phenotype of apple leaves overexpres
