Altered expression of pPLAIIIδ affects the endogenous auxin distribution. (A) pPLAIIIδ positively regulates DR5::GUS expression. One-week-old seedlings were subjected to GUS staining in the aerial portions of WT, KO and OE1 plants. Bar = 5 mm. (B) Changes in free IAA contents in intact seedlings, above-ground tissues and roots among WT, KO and OE1 plants. 7-day-old intact seedlings were grown vertically and collected to measure IAA contents. All values are the means ± SE of 3 biological replicates.
