Biosynthetic and signal transduction pathways of auxin. trpB, tryptophan synthase beta chain; Trp, tryptophan; DDC, tryptophan decarboxylase; TAA, tryptophan aminotransferase; TAM, tryptamine; IPA, indole-3-pyruvate; CYP71A13, indoleacetaldoxime dehydratase; IAOx, indole 3-acetaldoxime; YUCCA, indole-3-pyruvate monooxygenase; IAAld, Indole-3-acetaldehyde; IAN, Indole-3-acetonitrile; ALDH, aldehyde dehydrogenase; NIT, nitrilase; IAA, Indole-3-acetate; AUX/IAA, auxin-responsive protein IAA; ARF, auxin response factor; TIR1, transport inhibitor response 1; SAUR, small auxin up-regulated RNA. GL, non-senescing leaves, fully expanded green leaves; YL, senescing leaves, completely yellow; almost 95% chlorophyll loss. The colored cells represent the expression profiles of differentially expressed genes (DEGs). Heatmaps were generated by Rpackage and the color bar at the lower right. Orange dots show the fold change of the content of compounds in non-senescing and senescing leaves
