PIN3 regulates low R:FR-induced hypocotyl elongation and free IAA accumulation. (A) Different pin-like (pin) mutants were grown for 5 d under both control and low R:FR light conditions. The data shows that pin3-3 lacks the elongation response of the hypocotyl induced by low R:FR treatment, whereas pin4-2 and pin7 had a wild-type–like response. Data are mean (n = 25–41) ± SE; the Genotype * Light interaction is significant in all panels (P < 0.05) and different letters indicate significant differences between means (P < 0.05). (B) The levels of free IAA were measured on both Col-0 and pin3-3 hypocotyls after 2 d of low R:FR or control light treatment. Data are means (n = 4–5) ± SE; the Genotype × Light interaction is significant in all panels (P < 0.05). Different letters or asterisk (*) indicate significant differences between means (P < 0.05).
