Regulatory effects of PpbHLH1 on linalool synthesis in peach fruit. (a) Overexpressing PpbHLH1 induces expression of PpTPS3 and linalool accumulation in peach fruits. Empty SK vector was used as a control. Significant differences are indicated with asterisks above the bars (*, P < 0.05; **, P < 0.01; and ***, P < 0.001). (b) Chiral GC‐MS analysis of linalool enantiomers in transiently overexpressed peach fruits. (c) Silencing PpbHLH1 by VIGS decreases PpTPS3 expression and linalool content in peach fruit. Empty pTRV1 + pTRV2 vector was used as a control. (d) Changes in transcript levels and DNA methylation levels of PpTPS3 and PpbHLH1 during peach fruit ripening. (e) Effects of UV‐B irradiation on transcript levels and DNA methylation levels of PpTPS3 and PpbHLH1 in peach fruit. (f) A proposed regulatory model of linalool synthesis in peach fruit.
