ABC Model of Flower Development Plants - Biology …

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. WebSep 30, 2016 · The well-known ABC model describes the combinatorial interaction of homeotic genes in specifying floral organ identities.
