Figure 6.
Expression levels of genes in ABA biosynthetic and metabolic pathways, IAA biosynthetic pathway and SA biosynthetic pathway. In both treatment groups, the relative expression changes of all organs in all sampling stages were log2 times of that in flower at veraison stage. Key genes (ertZ, ZEP, NCED1, ABA3, AAO3, CYP707A, BG1, UGTs, TAR1, TAA1, CYP79B, AMI, YUC1, AAO, NIT, PAL, ICS, BA2H and IPL) expression levels were reflected as heat map. * Indicates a significant difference between the two treatments, while ** indicates an extremely significant difference between the two treatments. (A) ABA biosynthesis and metabolic pathway. (B) IAA biosynthesis pathway. (C) SA biosynthesis pathway.
