a, Number of significantly differentially expressed (DE) genes in the mesophyll, the epidermal cell class (combining epidermis, guard and trichome cell types) or vasculature cell class (combining phloem, xylem, bundle sheath, hydathode and myrosin idioblast cell types) in response to treatment with ABA, MJ, ACC, BR, 2,4-D, SA, CK as trans-zeatin and GA. b, Single-nuclei expression responses to exogenous hormone treatment of ACD6, INDUCED BY CYTOKININ 7 (IBC7) and CLE-LIKE 9 (CLEL9) in epidermal, mesophyll and vasculature cell-type clusters, respectively. c, Pie charts show the relative distribution of hormone-responsive genes across epidermal, mesophyll and vasculature cell types for each hormone treatment. Only genes associated with leaf ageing and perturbed by drought are included. d, Induction (red) or repression (blue) of genes responsive to one of four hormone treatments, plotted against their corresponding induction or repression in response to leaf ageing or drought stress (axis units are coefficients of linear model). Histograms next to each axis show the cell-type class in which the hormone-responsive gene was detected.
