Analysis of differential gene expression between WT and arf4 mutant tomato plants. (A) Numbers of differentially expressed genes (DEGs) between WT and arf4 mutants under unlimited water supply and under water stress conditions, (B) overlap of these genes set. (C) Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of DEGs specifically expressed in arf4 plants under water stress and (D) heatmaps of six DEGs differently expressed between WT and arf4 plants under conditions of unlimited water supply and water stress. WT and arf4 under water stress are represented by WT-D and arf4-D (auxin response factor ARF4-D), respectively.
