Molecular mechanisms of flower development: an armchair guide
Sep 1, 2005 · Most flowering-plant embryos undergo a stereotypical pattern of cell divisions to form a simple structure with a radial axis and an apical–basal axis 5. The radial axis establishes the...

Aug 8, 2023 · Floral radial and dorsoventral axes are established de novo within the plane of the floral meristem: the radial axis defines four concentric whorls of floral organs (i.e., sepal, petal,...
30.12: Plant Development - Genetic Control of Flowers
Oct 31, 2023 · ABC Model of Flower Development. In the simple ABC model of floral development, three gene activities (termed A, B, and C-functions) interact to determine the developmental identities of the organ primordia (singular: primordium) within the floral meristem.
The ABC model of floral development: Current Biology - Cell Press
Sep 11, 2017 · The outermost marginal flowers, or ‘ray’ flowers, are asymmetrically shaped, with one extremely enlarged petal and non-functional stamens that do not develop beyond a rudimentary stage. The inner ‘disc’ flowers have considerably reduced petals, but do possess functional stamens and carpels.

Dec 22, 2022 · Determination of the expression pattern of ABC genes provided strong support to ABC model as each gene is expressed in the region of flower that displays flower homeotic conversions when mutated (Reichmann and Meyerowitz 1997).
Morphogenesis of Flowers—Our Evolving View - Oxford Academic
Feb 1, 2005 · Radially symmetric flowers (also called regular or actinomorphic) have two or more axes and include many monocots (3), Arabidopsis (2, derived from 4), tomato, and Petunia (5). Bilaterally symmetric flowers (also called irregular, zygomorphic, or mirror-imaged) have only one and include Antirrhinum and the pea family (Papilionaceae).

Jan 1, 2023 · Generation of four compartments along the radial axis and the ABC model. The ABC model (Weigel and Meyerowitz, 1994; Coen, 1996, 1999; Irish, 1999; Krizek and Fletcher, 2005) involves three gene classes, A, B, and C, four concentric-ring compartments (whorls) and the combinatorial code shown in Fig. 2 e. The central open question is how this ...
An everlasting pioneer: the story of Antirrhinum research
Aug 1, 2003 · Several mutations affect the dorso–ventral axis of the flower. radialis (and cycloidea) mutants have enhanced ventral identity of lateral and dorsal petals (Ab).
