Phenotype
Strong allele; ovules lack integuments, embryo sac does not develop; ovule primordia form and develop normally through very early stages, but in later stages in place of the two integument primordia, only a slightly elevated ridge of cells (integumentary ridge) forms at the chalaza of the ovules and demarcates the nucellus and the funiculus but undergoes no further expansion, development of other parts of the ovule does not immediately arrest, minimal 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.
