WebIt suggests that TORC is present in the stele, the activated pericycle, founder cells, and forming LR. We also monitored in which cells S6K1 is expressed using a CFP-tagged genomic clone. This reporter specifically marked the actively dividing LR founder cells (Fig 3D), confirming an earlier report (Zhang et al, 1994). These results suggest ... WebLRP founder cells: they were found only in the xylem-adjacent pericycle where all LRPs initiate and were distal to the youngest LRPs, which is consistent with the acropetal pattern of LRP initiation (12, 14, 19). To test whether these DR5-expressing pericycle cells were in fact founder cells, we followed the fate of
WebApr 1, 2003 · The Arabidopsis root has a simple anatomy composed of single layers of epidermal, cortical and endodermal cells surrounding the vascular tissues [ 2 ]. Lateral roots in Arabidopsis are derived from a subset of pericycle cells termed pericycle founder cells, which are adjacent to the two xylem poles [ 3 ] ( Box 1 ). Dubrovsky et al. [ 3 Webxylem pole, designated as ‘founder cells’, which retain the capacity to undergo (asymmetric) cell division higher up in the root when other cells have differentiated. A tight control of cell cycle progression in the xylem pole-associated pericycle cells is required for lateral root initiation, and this cell cycle
