Phenotype
Slightly 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 undergoes limited asymmetrical expansion at the chalaza and the ovules take on more of the characteristic S shape of wt ovules, intermediate 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 4 times to wt.
