MADS reloaded: evolution of the AGAMOUSsubfamily genes

摘要

AGAMOUSsubfamily proteins are encoded by MADS-box family genes. They have been shownto play key roles in the determination of reproductive floral organs such as stamens, carpels andovules. However, they also play key roles in ensuring a fixed number of floral organs bycontrolling floral meristem determinacy. Recently, an enormous amount of sequence data fornonmodel species have become available together with functional data on AGAMOUSsubfamily members in many species. Here, we give a detailed overview of the most importantinformation about this interesting gene subfamily and provide new insights into its evolution.
