Genetic control of flower shape in Antirrhinum majus

Instituto de Tecnologia Quimica e Biologica, Oeiras, Portugal. almeida@itqb.unl.pt

The asymmetric shape of the Antirrhinum corolla is determined by genes acting differentially along the dorsoventral axis of the flower. Genes so far identified determine asymmetry by acting in dorsal regions. We describe a gene, divaricata, which in contrast to previously identified genes acts in ventral regions of the flower. We show by the analysis of mutant combinations that the divaricata gene is negatively regulated by the dorsal genes cycloidea and dichotoma. In addition, we show by the analysis of chromosomal duplications that the divaricata gene acts in a dosage-dependent manner, suggesting that the level of its product is critical for determining ventral identities.
