Figure 7.

Mean levels of transcriptional expression (±SE) of (A) CsPPO1 and (B) CsPPO2 in treated tea leaves elicited by mechanical wounding supplemented with distilled water or regurgitant and intact control plants (C). CsGAPDH was used as a reference gene. For each time point, different letters indicate significant differences among treatments (p < 0.05, Duncan’s multiple range test, n = 5). The asterisks indicate significant differences between treatments and controls (* p < 0.05, Student’s t-test, n = 5).
