Formation and maintenance of the shoot apical meristem.
Development in higher plants is characterized by the reiterative formation of lateral organs from the flanks of shoot apical meristems. Because organs are produced continuously throughout the life cycle, the shoot apical meristem must maintain a pluripotent stem cell population. These two tasks are accomplished within separate functional domains of the apical meristem. These functional domains ...
متن کاملInitiation of shoot apical meristem in rice
In flowering plants, the fundamental body plan is constructed during embryogenesis. The fertilized egg first sets up apicalbasal, radial and dorsal-ventral axes, which are later partitioned to differentiate region-specific organs. The shoot and root apical meristems arise as terminal elements of apical-basal axes. The establishment of shoot apical meristem (SAM) during embryogenesis is a key ev...

A commentary on Establishment of embryonic shoot–root axis is involved in auxin and cytokinin response during Arabidopsis somatic embryogenesis Plant tissue culture and subsequent organogenesis have been regarded as part of the scientific roots of modern plant biotechnology (Sussex, 2008). Establishments of shoot apical meristem (SAM) and root apical meristem (RAM) are critical steps for somati...
متن کاملShoot meristem formation and maintenance.
The shoot apical meristem of higher plants is a self-maintaining stem cell system which gives rise to the entire above-ground part of a plant. In the past year, genetic and molecular studies have provided increasing insight into the processes of shoot meristem formation and maintenance, as well as into the relation between the apical meristem and its products.
