Arabidopsis as a Model for Understanding the Basics of Endosperm Development
- 963 Downloads
Arabidopsis thaliana has emerged as a model species for understanding the basic mechanisms of endosperm development that are conserved in many Angiosperms. In this work, we focus on the genetic, molecular and cellular studies in Arabidopsis that have contributed to our current knowledge. Although initially syncytial, the endosperm differentiates several domains, the origin and function of which will be reviewed. This syncytial phase is followed by a cellular phase. We discuss the mechanisms controlling transitions between the two major phases. This work also emphasizes the major role played by endosperm in the control of seed size. Such regulation involves complex co-ordination with other seed components and epigenetic controls.
