Hormone regulation of whitefly-regulated DEGs and hormone levels in whitefly-infested cassava. a-c Stacked bar graphs displaying number of whitefly-regulated tDEGs in ECU72 (a), tDEGs in COL2246 (b) and gDEGs (c) categorized by their hormone-response class. Hormone-response categories included responses to single or multiple defense hormones. Hormone categories that contributed to more than 10% of the whitefly-infestation response are shown. The hormone-response category “All” reflects the ability of a DEG to independently respond to SA, JA, ET, and ABA. The “WF” category indicates that DEGs responded to whitefly infestation but none of the defense hormones tested. The hormone category “Other” includes all single or multiple hormone-response categories that constitute less than 10% of whitefly-responsive genes at a time point. Gene counts by hormone category are provided in Additional file 21. d Defense hormones detected during infestation in ECU72 and COL2246. JA and JA-Ile were not detected and no significant changes in MeJA levels were observed during whitefly infestation of ECU72 or COL2246. Asterisks (red) indicate significant difference in hormone level between genotypes as identified by Student’s t-test (* = p ≤ 0.05). Complete lists of detected hormones and p-values is provided in Additional file 22 including SA, SAG (SA glucoside), MeJA (methyl jasmonate), 12-OPDA(12-oxo-phytodienoic acid), ABA, and PA (phaseic acid)
