The plants of mtpin1 mtpin3 fail to respond to low R:FR ratio light. (A) Relative expression levels of MtPIN1 and MtPIN3 at petiole in wild-type under white light (WL) and a low R:FR ratio light (R:FR ratio = 0.1). (B–E) Phenotype of 45-day-old wild-type (WT) (B), mtpin1-1 (C), mtpin3-1 (D), and mtpin1-1 mtpin3-1 (E) under a low R:FR ratio light. (F) The petiole length of wild-type and mutants under low R:FR light. (G–I) Relative expression levels of MtIAA19 (G), MtIAA29 (H), and MtHB2 (I) under low R:FR light. Values are the means and SD of three biological replicates. * p < 0.05, *** p < 0.001. Bars = 1 cm in (B–E).
