Towards a comprehensive and dynamic gynoecium gene regulatory network

Abstract

The Arabidopsis thaliana gynoecium arises at the center of the flower as a simple structure, which will successively develop novel cell types and tissues, resulting in a complex organ. Genetic and hormonal factors involved in this process have been identified, but we are still far from understanding how these elements interact, and how these interactions rearrange according to spatial and temporal cues. In this work we propose the first steps in a roadmap to attain an ambitious goal: to obtain a comprehensive and dynamic gene regulatory network that will help us elucidate the patterning events leading to the formation of a fully developed gynoecium.
