Validation of upstream regulators for the PbLAC4-like gene. a Y1H assay showing the interaction between PbMYB26 and the PbLAC4-like. b Effects of PbMYB26 on the promoter activity of PbLAC4-like in a dual luciferase assay. c Gene expression analysis after transient transformation PbMYB26 gene in ‘Zaosu’ fruit peel. The significant difference was determined by t test for three replicates: *P < 0.05; **P < 0.01. Error bars represent the means ± SEM of biological replicates
