Regulation of potato vegetative growth by phytohormones and inorganic elements, and leaf senescence by environmental stimuli. Genes ANR1, NRT1, and PHO1, and inorganic nutrient elements nitrogen, magnesium, and phosphorus, regulate root development of potato. MicroRNAs and phytohormones regulate leaf development. Circadian clock, SA/ROS, ABA, stress, secondary metabolites, and sucrose regulate leaf senescence through various pathways. StABL1 and StABI5, ABA signalling pathway transcription factors; StUBA2a/b and StUBA2c, the NA-binding proteins; StSWEET11/15/10C, sucrose transporters
