The homeotic gene APETALA3 of Arabidopsis thaliana encodes a MADS box and is expressed in petals and stamens.

Cell - 21 Feb 1992

Jack T, Brockman L L, Meyerowitz E M

Abstract excerpt

Mutations in the APETALA3 (AP3) gene of A. thaliana result in homeotic transformations of petals to sepals and stamens to carpels. We have cloned the AP3 gene from Arabidopsis based on its homology to the homeotic flower gene deficiens (DEFA) from the distantly related plant Antirrhinum majus. The sequence of four ap3 mutant alleles and genetic mapping analysis prove that the DEFA homolog is AP3. Like several...
