Biosynthetic and signal transduction pathways of jasmonic acid. LA, phospholipase A1; α-LeA, alpha-Linolenic acid; LOX, lipoxygenase; 12,13-HPOT, 12,13-hydroperoxylinoleic acid; AOS, allene oxide synthase; 12,13-EOT, 12,13-epoxyoctadecatrienoic acid; AOC, allene oxide cyclase; OPDA, oxophytodienoic acid; OPR, oxophytodienoic acid reductase; JA, jasmonic acid; JMT, jasmonic acid carboxyl methyltransferase; JAR1, jasmonic acid resistant 1; MeJA, Methyl jasmonate; JA-Ile, Jasmonoyl-L-isoleucine; COI1, coronatine-insensitive protein 1; JAZ, jasmonate ZIM domain-containing protein. GL, non-senescing leaves, fully expanded green leaves; YL, senescing leaves, completely yellow; ~ 95% chlorophyll loss. Colored cells represent the heatmaps of differentially expressed genes (DEGs). With the heatmaps, the redder the color, the higher the DEGs expression, and the greener the color, the lower the DEGs expression. Orange dots show the fold change the content of the compounds in non-senescing and senescing leaves
