The proposed mechanisms for jasmonates (JAs) inducible PpZAT5 and PpBBX32 modulating cultivar/temperature/tissue-dependent anthocyanin accumulation in peach fruit. The JA content in outer flesh near the peel (OF) of ‘Zhonghuashoutao’ (‘ZHST’) stored at 16°C for 15 d or 30 d and the inner flesh around the stone (IF) of ‘ZHST’ was high, while those in OF of ‘Dongxuemi’ (‘DXM’) stored at a temperature between 0°C and 16°C as well as in OF of ‘ZHST’ stored at ≤12°C was low. The high JAs level stimulated the expression of PpBBX32 and PpZAT5, with detailed mechanisms currently not revealed, and these two TFs then upregulated the expression of PpMYB10.1 by directly bound to its promoter. Moreover, these two TFs also fulfil their function by forming a protein complex in the order PpZAT5-PpBBX32-PpMYB10.1 which ultimately promoted anthocyanin accumulation in peach.
