Phenotype

Weak allele; ovules lack integuments, embryo sac does not develop; ovule primordia form and develop normally through early stages, but in later stages, in place of the two integument primordia, an integumentary ridge of cells expands further at the chalaza and, in some cases, partially surrounds the nucellus and superficially resembles an outer integument, normal chalazal bend; altered flower development: narrow petals with somewhat irregular margins, reduced stamen number; complete female sterility; expressed specifically in the chalaza and in floral organ primordia; encodes a protein with similarity to the product of the APETALA2 gene. Backcrossed twice to wt.
