MdMYB30 participates in the biotic and abiotic stress response. a Identification of ectopically expressed Arabidopsis thaliana expression level of MdMYB30 by qRT-PCR. b Phenotype of wild-type and MdMYB30 ectopically expressed Arabidopsis treated with or without 10 μM flg22, 30 μM flg22, 2% PEG, 4% PEG, 10 μM ABA, or 20 μM ABA (scale bar: 1 cm). c-e Root length c, fresh weight d, and chlorophyll content e in b Arabidopsis seedlings. Arabidopsis chlorophyll μmol/g FW (fresh weight = FW). Error bars represent standard deviation (SD; n = 3). Data are mean ± SD of three independent replicates. Different lowercase letters indicate significant differences at P < 0.05
