UMAPs and accompanying violin plots display a candidate gene’s differential expression patterns in response to a hormone treatment within a cell-type class. (a - c) The mesophyll cell-type differentially expresses either INDUCED BY CYTOKININ 7 (IBC7), RESPONSE TO DESICCATION 29 A (RD29A), or DORMANCY-ASSOCIATED PROTEIN-LIKE 1 (DYL1) in response to trans-Zeatin (CK), abscisic acid (ABA), or brassinolide (BR) treatment, respectively. (d - f) The epidermal cell-class (combining epidermal, guard and trichome cell types) differentially expresses either ACCELERATED CELL DEATH 6 (ACD6), EXPANSIN A1 (EXP1), or LIPOXYGENASE 2 (LOX2) in response to salicylic acid (SA), gibberellin (GA) or methyl jasmonate (MJ), treatment respectively. (g - h) The vasculature cell-class (combining phloem, xylem, bundle sheath, hydathode, myrosin idioblast cell types) differentially express either CLE LIKE 9 (CLEL9) or ETHYLENE RESPONSE FACTOR 72 (ERF72) in response to either synthetic auxin (2,4-D) or ethylene precursor 1-Aminocyclopropane-1-carboxylic acid (ACC) respectively. Differential expression was assessed using a likelihood ratio test (adj. p indicated, see Methods). Additional hormone-responsive genes are listed in Supplementary Table 6.
