Overexpression of MdWRKY31 affects the expression of cell wall‐modifying enzymes. (a) Number of differentially expressed genes (DEGs) in the biological processes of the two MdWRKY31 transgenic apple lines. (b) Venn diagram of differentially expressed genes co‐regulated in the two MdWRKY31 transgenic apple lines. (c) Subset of the 16 cell wall–associated DEGs, annotation, functional categories, and expression (log 2 of reads per kilobase million). (d) Expression of genes involved in cell wall modification in WT and MdWRKY31 overexpressed apple leaves. The experiments were performed in three technical replicates with two technical repetitions for each biological sample. Error bars indicate ± SD.
