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 ...
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 ...
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 ...
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 ...
Superman (gene) Superman is a plant gene in Arabidopsis thaliana, that plays a role in controlling the boundary between stamen and carpel development in a flower. [1] It is named for the comic book character Superman, and the related genes kryptonite (gene) and clark kent were named accordingly (although, appropriately, the latter turned out to ...
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 ...
Photo of the plant in bloom in 2000 at Fairchild Tropical Botanic Garden in Miami, Florida, US. An inflorescence, in a flowering plant, is a group or cluster of flowers arranged on a stem that is composed of a main branch or a system of branches. [1] An inflorescence is categorized on the basis of the arrangement of flowers on a main axis ...
The members of the MADS-box family of transcription factors play a very important and evolutionarily conserved role in flower development. According to the ABC Model of flower development, three zones — A, B and C — are generated within the developing flower primordium, by the action of some transcription factors, that are members of the ...
