The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower. There are three physiological developments that must occur in … See more The transition from the vegetative phase to a reproductive phase involves a dramatic change in the plant's vital cycle, perhaps the most important one, as the process must be carried out correctly in order to guarantee that the … See more A flower's anatomy, as defined by the presence of a series of organs (sepals, petals, stamens and carpels) positioned according to a given pattern, facilitate sexual reproduction See more General texts • Soltis, DE; Soltis, PS; Leebens-Mack, J, eds.

PMC 4844379 See more WebThe ABC model of flower development explains how three classes of floral genes specify the identity of the four whorls of the flower. Our initial study related to this grant focused on three closely related MADS-box genes, termed SEP1, SEP2 and SEP3.
WebThe ABC model for the specification of floral organ identity, published 15 years ago, has proven to be a useful framework for interpreting floral development data from a wide variety of species. In Arabidopsis, A‐function (specification of sepal and petal identity) is attributed to two unrelated genes, APETALA1 ( AP1) and APETALA2 ( AP2 ). Web3.1 Emergence of ABC model. Over the last couple of decades, a great number of flower abnormalities that could be traced to specific genes were reported by genetics. Such reports were scattered in the botanical, horticultural, and genetic literature or for considerations that the respective genes could be useful for the breeding of ornamental ...
WebThe well-known ABC model describes the combinatorial interaction of homeotic genes in specifying floral organ identities. While the B- and C-functions are highly conserved throughout flowering plants and even in gymnosperms, the A-function, which specifies the identity of perianth organs (sepals and petals in eudicots), remains controversial. WebReview the ABC model for flower development in Arabidopsis shown below. Which of the following statements about the ABC model is incorrect? A. Activity A alone results in the …
WebFeb 1, 2010 · The ABC model was formulated from the analysis of three classes of floral homeotic mutants with organ identity defects in two adjacent whorls of the flower. Importantly, similar classes of mutant were described in both Arabidopsis and Antirrhinum, suggesting that the regulation of organ identity was highly conserved in evolution [1].
WebThe ABC model is a simple model that describes the genes responsible for the development of flowers.

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. chuck elleyWebBackground: Although the flower is the central feature of the angiosperms, little is known of its origin and subsequent diversification.
