The relative expression levels of the CsBAHDs in tea leaves at different time points after feeding by tea geometrids. E3, E6, E9, E12, and E24 represent samples taken 3, 6, 9, 12, and 24 h after feeding, while CK3, CK6, CK9, CK12, and CK24 represent control samples at the corresponding time points. The expression levels were calculated based on the 2^−ΔCT method relative to the internal reference gene. The bars represent the mean ± SD (n = 3). Significant differences between the treatments and CK were determined by Student’s t test (*p < 0.05, **p < 0.01, ns: no significant difference)
