Expression profiles of ABA biosynthetic and catabolic genes in the root of WT tomato and CCD8 RNAi line under normal P and P starvation. A, schematic representation of ABA biosynthesis and inactivation [82]: I represents carotenoid precursor biosynthesis; II represents the formation of epoxycarotenoids and their cleavage in the plastids, III represents reactions in the cytosol for the formation of ABA. B, hierarchical clustering diagram of ABA biosynthesis pathway related genes in WT at 4-day normal P and P starvation. YP4 and NP4 represent tomato WT at 4Â days of control P and P starvation, respectively. CCD8.YP4 and CCD8.NP4 represent the CCD8 RNAi line at 4Â days of control P and P starvation, respectively.
