ARF8 Exhibits High Expression Levels in Petals.

(A) qPCR analyses of ARF8 mRNA in sepals (Se), petals (Pe), stamens (St), and carpels (Ca) at flower development stages 9 and 13. Expression value of ARF8 in sepals was set to 1, and the relative ARF8 expression in the different flower organs is presented. Each value represents the mean of three biological replicates ± se.

(B) and (C) qPCR analyses of ARF8 mRNA accumulation (B) and of BPEp mRNA accumulation (C) in bpe-1 and arf8-3 inflorescences. WT, wild type.
