Silencing GhVIN1 reduced the transcript levels in −1-d stamen of candidate genes for starch synthesis and degradation (A), auxin biosynthesis (B), and JA response (D) and altered the expression of some auxin signaling genes (C). Data represent means ± se (n ≥ 6), generated from the same biological replicates as in Figure 6E. Asterisks indicate significant differences (one-way ANOVA; *, P < 0.05; **, P < 0.01; and ***, P < 0.001) between RNAi and wild-type plants (WT).
