REVOLUTA regulates meristem initiation at lateral positions.
While the shoot apical meristem (SAM) is indirectly responsible for the initiation of all above-ground postembryonic organs, in most plants the vast majority of these organs are directly initiated by lateral meristems. In Arabidopsis thaliana, the lateral meristems include flower meristems (FMs), which form on the flanks of the SAM, and lateral shoot meristems (LSMs), which develop in leaf axil...
متن کاملBlind homologous R2R3 Myb genes control the pattern of lateral meristem initiation in Arabidopsis.
In seed plants, shoot branching is initiated during postembryonic development by the formation of secondary meristems. These new meristems, which are established between the stem and leaf primordia, develop into vegetative branches or flowers. Thus, the number of axillary meristems has a major impact on plant architecture and reproductive success. This study describes the genetic control of axi...
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...
متن کاملAuxin–Cytokinin Interaction Regulates Meristem Development
Plant hormones regulate many aspects of plant growth and development. Both auxin and cytokinin have been known for a long time to act either synergistically or antagonistically to control several significant developmental processes, such as the formation and maintenance of meristem. Over the past few years, exciting progress has been made to reveal the molecular mechanisms underlying the auxin-...
متن کاملCytokinin Signaling Activates WUSCHEL Expression during Axillary Meristem Initiation.
The homeodomain transcription factor WUSCHEL (WUS) defines the shoot stem cell niche, but the mechanisms underlying the establishment of WUS expression remain unclear. Here, we show that cytokinin signaling precedes WUS expression in leaf axils and activates WUS expression de novo in the leaf axil to promote axillary meristem initiation. Furthermore, type-B Arabidopsis response regulator protei...
