Abstract
Angiosperms are the most dominant vascular plants with a bewildering array of morphological differences amongst the 250000 extant species. The ABC floral model was developed from a few model dicots and expanded to encompass most or all angiosperms. However, the data supporting this extends only to the formation of reproductive organs and the MADS-box factors specifying their identity. Arabidopsis is the only species where much is known about the A-function, which controls the identity of the perianth. In no other species have all the relevant genes and mutants been available. In Antirrhinum we have isolated homologues of the Arabidopsis A-function genes AP2 and ANT and their respective transposon insertion mutants. This, together with the pre-existing ABC mutants, provides us with the first opportunity to perform a complete comparative analysis of the A- function.
