qRT-PCR analysis of PIN family genes in the junction of wild-type (WT) and strigolactone-deficient (d10) and strigolactone-insensitive (d3) mutant rice plants. Rice seedlings were grown for 3 weeks in hydroponic media with or without 1·25 µm GR24. (A) WT, d10 and d3 mutants. (B, C) WT (B) and d10 (C) with or without GR24 application. Relative mRNA levels were normalized for individual genes relative to OsACT. Data are mean ± s.e. Different lower-case letters in the same gene indicate significant differences (P < 0·05, ANOVA).
