Brief Introduction
- MADS-box family member are known to be involved in many important processes during plant growth and development[1][2][3]. The word MADS finds its origin from the first letters of its founding members, Mini Chromosome Maintenance 1 (MCM1) of yeast (Saccharomyces cerevisiae), Agamous (AG) of Arabidopsis (Arabidopsis thaliana), Deficiens (DEF) of snapdragon (Antirrhinum majus) and Serum Response Factor (SRF) of humans (Homo sapiens)[1].
- They are characterized by the presence of a conserved domain of approximately 60 amino acids located in the N-terminal region; this domain is named the MADS-box domain and is involved in DNA binding and dimerization[1][2][3]. The MADS-box family has been divided into two main groups. The type I consists of ARG80/SRF-like genes of animals and fungi, also designated as M-type genes in plants, and type II contains MEF2-like genes of animals and yeast as well as MIKC-type genes of plants[1][3].
- The best studied plant MADS-box transcription factors are those involved in floral organ identity determination. Combinations of A-, B-, and C-function genes determine the development of the four whorls of an Arabidopsis flower: A-function genes determine sepal development; A- and B-function genes determine petal development; B- and C function genes determine the stamen development, and C-function genes are necessary for carpel development[2][3].
