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 ...

WebSep 30, 2016 · The 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 … 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].

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 of flower development was first formulated by George Haughn and Chris Somerville in 1988.
