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 order for this to take place: firstly, the ...
Arabidopsis thaliana is a first class model organism and the single most important species for fundamental research in plant molecular genetics . A. thaliana was the first plant for which a high-quality reference genome sequence was determined (see below), and a worldwide research community has developed many other genetic resources and tools ...
The ABC model is a simple model that describes the genes responsible for the development of flowers. Three gene activities interact in a combinatorial manner to determine the developmental identities of the primordia organ within the floral apical meristem. These gene functions are called A, B, and C. Genes are expressed in only the outer and ...
Plant evolutionary developmental biology. Evolutionary developmental biology (evo-devo) is the study of developmental programs and patterns from an evolutionary perspective. [1] It seeks to understand the various influences shaping the form and nature of life on the planet. Evo-devo arose as a separate branch of science rather recently.
Apetala 2 (AP2) is a gene and a member of a large family of transcription factors, the AP2/ EREBP family. In Arabidopsis thaliana AP2 plays a role in the ABC model of flower development. [2] It was originally thought that this family of proteins was plant-specific; however, recent studies have shown that apicomplexans, including the causative ...
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
Plant development. Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems [ 1] located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues. By contrast, an animal embryo will very ...
