The ultimate fate of the flower is to become a fruit, ensuring dispersal of the seeds and therefore survival of the species. The Arabidopsis fruit is a silique or pod. Only in the last five years important advances have been made in establishing the differentiation of the tissues required for the opening of the fruit: the valve margins and ...

2015年7月1日 · Although several studies have explored gene expression during flower development in the model plant Arabidopsis thaliana on a genome-wide scale, a continuous series of expression data from the earliest floral stages until maturation has been lacking. Here, we used a floral induction system to close this information gap and to generate a ...

Floral organs show two patterns of initiation, a leaf-like pattern with eight cells in a row (sepals and carpels), or a shoot-like pattern with four cells in a block (stamens). The petal initiation pattern involved too few cells to allow assignment.

1990年8月1日 · The early development of the flower of Arabidopsis thaliana is described from initiation until the opening of the bud. The morphogenesis, growth rate, and surface structure of floral organs were recorded in detail using scanning electron microscopy. Flower development has been divided into 12 stages using a series of landmark events.

2021年2月22日 · We have analyzed the link between the gene regulation and growth during the early stages of flower development in Arabidopsis. Starting from time-lapse images, we generated a 4D atlas of early flower development, including cell lineage, cellular growth rates, and the expression patterns of regulatory genes.

Genetic studies in Arabidopsis thaliana and Antirrhinum majus led to the proposal of the landmark ABC model of flower develop-ment (Bowman et al., 1991, Coen and Meyerowitz, 1991). This model proposes that three different activities, A, B and C, alone or in combination specify the distinct organs of the four whorls of the flower.

Flowers are the most complex structures of plants. Studies of Arabidopsis thaliana, which has typical eudicot flowers, have been fundamental in advancing the structural and molecular understanding of flower development. The main processes and stages of Arabidopsis flower development are summarized t …

1991年1月1日 · By studying the phenotypes of a series of homeotic mutations, each of which affects flower development in the mustard Arabidopsis thaliana, we have derived a simple working model for the process by which groups of cells in the developing flower ‘choose their fate’. The model is consistent with the phenotypes of the mutations, and correctly ...

This review focuses on the current knowledge of the genetic basis of flower patterning in Arabidopsis thaliana. Flower patterning requires several steps: the specification of lateral meristems as flowers instead of shoots, the establishment of proper floral organ identity, and the initiation of organs in correct number and positions.

A second significant ning in the early 1980s of mutations in Arabidopsis difference is that post-embryonic development in higher thaliana or Antirrhinum majus that alter either floral plants gives rise to all of the adult structures of the plant induction or floral meristem fate or floral organ fate through the activity of specialized groups of ...
