Schematic diagram of major plant hormone signal transduction pathway for sorghum (adapted from KEGG, yellow highlights are pathway name, dotted arrow represents multiple enzymatic steps, green highlights are genes in respective pathways). AUX—auxin influx carrier; TIR1—transport inhibitor response1; AUX/IAA—auxin/indole-3-acetic acid; ARF—auxin response factor; GH3—auxin responsive Gretchen hagen3; SAUR—small auxin upregulated RNA; COI1—coronatine-insensitive protein 1; JAZ—jasmonate ZIM-domain; MYC2—transcription factor MYC2; NPR1—regulatory protein NPR1; TGA—transcription factor TGA; PR-1—pathogenesis related-1; PYR/PYL—abscisic acid receptor PYR/PYL family; PP2C—protein phosophatase 2C; snRK2—serine/threonine-protein kinase; ABF—ABA responsive element biding factor.
