The involvement of OspPLAIIIα in gibberellin (GA) response. (A) The growth response of WT, KO, and OE seedlings grown in liquid medium without and with 500 μM GA₃ for 14 d. (B) The plant height of OspPLAIIIα-alterated seedlings treated with and without GA₃ for 14 d. Values are means ±SD (n=6). (C) Transcript level of genes involved in GA synthesis, degradation, and response. The level was measured by real-time PCR and normalized to β-actin. a, b, c, and d indicates different expression levels between treated and untreated plants within each genotypes according to ANOVA, P<0.05. Values are means ±SD (n=3). (This figure is available in colour at JXB online.)
