Stem-specific DEGs are associated with secondary metabolism. a Summary of affected metabolites and pathways between drought stressed EV and SPL13RNAi stem tissues, b distribution of the differentially expressed genes associated with secondary metabolism. Pathway analysis was performed using MapMan. Transcript fold changes are provided in log 2 with red and blue colours representing an increased and decreased transcript levels relative to EV. Minor CHO corresponds to minor charbohydrate; TCA, Tricarboxylic acid cycle; OPP, oxidative pentose phosphate pathway; MVA, mevalonate pathway. N = 3 biological replicates for each genotype and treatment condition
