Plant morphogenesis: long-distance coordination and local patterning.

摘要: The overall morphology of a plant is largely determined by developmental decisions taken within or near the terminally positioned apical meristems shoots and roots. spatial separation these centers emphasizes need for long-distance signaling. same signaling events may simultaneously coordinate differentiation in connecting vascular tissues. Recent genetic molecular analyses not only confirm proposed role auxin as coordinating signal across plant, but also implicate patterning embryo meristem organization.
