WebFlower organ identity. A great deal of attention has focused on the genes that specify organ identity, leading to the "ABC" model of flower development. This model proposes that at around the time of organ initiation, the flower meristem is partitioned into three overlapping fields of gene activity, with each field defining two adjacent whorls. WebThe ABC model and flower evolution Given the conservation of floral organ position across angiosperms, it was a natural question as ask whether the ABC model could be applied to all flowering plants – and not only to Arabidopsis and snapdragon, where it was developed.
