ABA content and expression levels of ABA metabolism-related genes in 2-week-old apple calli. a ABA content. b-f Expression levels of ABA metabolism-related genes. WT: wild-type; MdNAC4-OX: with MdNAC4 overexpression vector; MdNAC4-Anti: with MdNAC4 antisense vector. The WT expression level was set at 1. Error bars indicate the SDs of the three technical replicates and three biological replicates. Asterisks indicate significant differences between two independent samples according to t tests (*, P < 0.05 and **, P < 0.01)
