The war of the whorls: genetic interactions controlling flower development

Nature. 1991 Sep 5;353(6339):31-7. doi: 10.1038/353031a0.


The analysis of mutations affecting flower structure has led to the identification of some of the genes that direct flower development. Cloning of these genes has allowed the formulation of molecular models of how floral meristem and organ identity may be specified, and has shown that the distantly related flowering plants Arabidopsis thaliana and Antirrhinum majus use homologous mechanisms in floral pattern formation.
