Fig 7. Determination of SA, JA, ABA, ZT and ET contents in the 1–9 and L-5 transgenic citrus lines overexpressing CsGH3.1 and CsGH3.1L, respectively.

Hormones were isolated from six fully expanded intact leaves per line. Error bars represent the mean standard errors of three independent measurements. Different letters on top of bars represent significant differences from wild-type (WT) controls based on Tukey’s test (P < 0.05).
