Regulation of Petal Growth by BPEp Is Independent of ARF6.
(A) Fully expanded petals at flower development stage 14 in wild-type (WT), bpe-1, arf6-2, and bpe arf6 plants.
(B) Surface area measurements of mature petals (stage 14) in bpe-1, arf6-2, bpe arf6, and wild-type plants. Values are given as mean ± se relative to the wild-type value, set at 100%.
