Sepal axil secondary flower phenotype in ap1 mutants. Vertical view of a wild type flower in (A), lateral view of a wild type flower in (B), and top view of a wild type inflorescence in (C). Vertical view of an ap1-1 flower in (D), lateral view of an ap1-1 flower in (E), and top view of an ap1-1 inflorescence in (F). Vertical view of an ap1-4 flower in (G), lateral view of an ap1-4 flower in (H), and top view of an ap1-4 inflorescence in (I). Note ectopic sepal axil secondary flowers in ap1 mutants.

Partial rescue of the ap1 axil flower phenotype by local manipulation of CKX3 and LOG1 expression. (A) Siliques phenotypes of ap1-4, pAP1::CKX3 ap1-4 and silencing pAP1::LOG1 ap1-4. Siliques were taken at the same position of inflorescence. (B) Mean number of flowers (per pedicel) of ap1-4, pAP1::CKX3 ap1-4 and pAP1::amiR-LOG1 ap1-4 plants. Blue represents wild-type, purple represents pAP1::CKX3 ap1-4 and white represents pAP1::amiR-LOG1 ap1-4.
