Expression of differentially expressed genes related to the auxin pathway. RNA was extracted from young uppermost internodes at the heading stage. The expression levels of OsYUCCA7 (A), OsGH3.8 (B), OsIAA14 (C), and OsIAA24 (D) were analyzed by qRT-PCR. Note that OsGH3.8 was activated in G312 and G316. The oligonucleotide sequences used for qRT-PCR are listed in Supplemental Table S2. The rice OsACTIN1 gene (Os03g50885) was used as an internal control. Asterisks indicate significant differences in comparison with TP309 (**, P < 0.01, Student’s t test).
