Schematic diagram showing the regulation of multiple pathways in response to high and low nitrate conditions in plants. Only the paths discussed in the present study are illustrated. Signaling pathways lead to the onset of leaf senescence. Black arrows indicate positive regulation of ABA; abscisic acid; IAA, indole-3-acetic acid; JA, jasmonic acid; SAGs, genes associated with senescence; TGA1; TGACG motif-binding factor, NRT, nitrate transporter; PLC, phospholipase C; ARF, auxin response factor transcription factors, and red lines indicate a negative signal as an inhibitory effect. Low nitrate and extremely low nitrate conditions have stimulatory and inhibitory effects on LR development, respectively, while high NO3 supply has an inhibitory effect on LR growth
