Cell Differentiation in Shoot Meristem: A Molecular Perspective

摘要: The basic body plan of higher plants is laid down during embryogenesis, however, the entire adult plant develops post-embryonically through activity two meristems (shoot and root apical meristems) established originally at opposite ends embryo. This article focuses on shoot meristem (SAM), which primarily responsible for formation leaves stems in vegetative phase converts into reproductive a specific stage development. SAM comprises central zone harboring reservoir pluripotent stem cells peripheral zone, gives rise to primordia organs such as flowers. Studies past decade have unravelled some molecular pathways that determine cell fate portion well regulate organ from SAM. These studies are providing insight information flow between various zones layers helps stabilizing size population, so vital cellular proliferation regulation growth
