ZmMYB31 modulates the phenylpropanoid pathway of maize drought response. A, B RNA-seq and CUT&Tag data showing that Phenylalanine ammonia lyase7 (PAL7) is positively regulated by ZmMYB31 (data are means ± SD; three replicates, “**” represents P < 0.01). C, D RNA-seq and CUT&Tag showing that ZmC4H (Zm00001d012510) is likely to be positively regulated by ZmMYB31 (data are means ± SD; three replicates). E Putative regulatory network curated from public ChIP-seq data [26]. F Some TF genes in E are targeted by MYB31 and show differential expression between mutant and WT. G Proposed model of ZmMYB31 regulated drought response through ABA signaling and the phenylpropanoid pathway
