ABC model of flower development
The ABC model of flower development is a scientific model that explains the process of flower development and formation. This model was first proposed by Elliot Meyerowitz and Enrico Coen in 1991.
Pronunciation
ABC model of flower development: /ˈeɪ.biː.siː mɒdəl ɒv ˈflaʊər dɪˈvɛləpmənt/
Etymology
The term "ABC model" is derived from the first three letters of the English alphabet, representing the three classes of genes involved in flower development. The term "flower development" refers to the biological process of growth and formation of a flower.
Definition
The ABC model of flower development is a scientific model that describes how three classes of genes work together to form the four types of floral organs: sepals, petals, stamens, and carpels. These genes are classified into three groups, known as A, B, and C.
- A-class genes are involved in the development of sepals and petals.
- B-class genes are involved in the development of petals and stamens.
- C-class genes are involved in the development of stamens and carpels.
In the absence of C-class genes, A-class and B-class genes can interact to form a flower with only sepals and petals.
Related Terms
