WebEasily the most recognizable accomplishment in plant developmental biology is the proposal of the landmark ABC model of flower organ identity, where the individual and combined … WebJul 6, 2007 · The ABC model posited that floral organ identity is controlled by three gene functions – A, B and C – that act in combination; A-function alone specifies sepal identity, A- and B-functions together control petal identity; B- and C-functions together control stamen identity; C-function alone specifies carpel identity (Fig. 2 A).
WebBackground: Although the flower is the central feature of the angiosperms, little is known of its origin and subsequent diversification. The ABC model has long been the unifying paradigm for floral developmental genetics, but it is based on phylogenetically derived eudicot models. ...

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. WebJun 1, 2024 · The ABC model in flower development represents a milestone of plant developmental studies and is essentially conserved across a wide range of angiosperm species. Despite this overall conservation, individual genes in the ABC model are not necessarily conserved and sometimes play a species-specific role, depending on the …
WebAdditional structures of the flower: ABC model of floral development: The four whorls of the flower: In general, a flower consists of four main parts that are arranged in four whorls and they are discussed as follows (figure A and B). Calyx: The outermost whorl is known as calyx that is green in color. Sepals protect the flower during the bud ...
WebJun 1, 2001 · About 10 years ago, the ABC model for the genetic control of flower development was proposed.
