...Marc Somssich; Byoung Il Je; Rüdiger Simon; David Jackson Shoot meristems are maintained by pluripotent stem cells that are controlled by CLAVATA-WUSCHEL feedback signaling. This pathway, which coordinates stem cell proliferation with differentiation, was first identified in Arabidopsis...

... meristems from cultured root explants is a widely used, but poorly understood, process in which apical plant tissues are regenerated from adult somatic tissue through the de novo formation of shoot meristems. We characterize early patterning during de novo development of the Arabidopsis shoot meristem using...

...Michael Lenhard; Thomas Laux Stem cell maintenance in the Arabidopsis shoot meristem is regulated by communication between the apical stem cells and the underlying organizing centre. Expression of the homeobox gene WUSCHEL in the organizing centre induces stem cell identity in the overlying...

... appears to occur mainly via repression of the MYB-related gene ASYMMETRIC LEAVES1 ( AS1 ), since loss of AS1 function in an stm mutant background rescues SAM formation ( Byrne et al., 2000 ). STM mRNA is expressed in the shoot meristem primordium from the globular embryo stage...

... and Nilsson, 1995 ). Thus, at lower nodes of the lfy inflorescence, TFL1 was ectopically expressed by the time shoot meristems were distinct from their subtending cauline leaf primordia. However, at the upper nodes of the lfy inflorescence, TFL1 was not found in the meristems that expressed AP1...

...Thomas Laux; Klaus F. X. Mayer; Jürgen Berger; Gerd Jürgens ABSTRACT Self perpetuation of the shoot meristem is essential for the repetitive initiation of shoot structures during plant devel-opment. In Arabidopsis shoot meristem maintenance is disrupted by recessive mutations in the WUSCHEL (WUS...
