OsNPR1 up-regulated OsGH3.8. A, Expression levels of GH3 family genes in the wild type and OsNPR1 overexpression lines G312 and G316. RNA was extracted from 3-week-old seedlings. qRT-PCR was performed with the OsACTIN1 gene (Os03g50885) as an internal control, and expression levels of the genes in wild-type TP309 were set as 1. Asterisks indicate significant differences in comparison with wild-type TP309 (**, P < 0.01, Student’s t test). B, Expression levels of OsGH3.8 in OsNPR1 overexpression line G316 and two transgene-silenced G316 plants (S1 and S2). Different letters indicate significant differences (P < 0.05, ANOVA followed by Duncan’s multiple range test).
