... in the shoot apical meristem and the regulation of quiescent center (QC) cell division in roots. We show that TPL binds via BES1 to the promoters of the CUC3 and BRAVO targets and suppresses their expression. Ectopic expression of TPL leads to similar organ boundary defects and alterations in QC cell division...

... originate from pericycle cells, which undergo a program of morphogenesis to generate a new lateral root meristem. Despite its importance for root meristem organization, the onset of quiescent center (QC) formation during lateral root morphogenesis remains unclear. Here, we used live 3D confocal imaging...

The quiescent center (QC)in the RAM and the organizing...

...Keni Jiang; Yu Ling Meng; Lewis J. Feldman Embedded within the meristem of all Angiosperm roots is a population of slowly dividing cells designated the quiescent center (QC). In maize roots the QC can constitute upwards of 800-1200 cells, most of which spend an extended period of time (180-200...

...Nancy M. Kerk; Lewis J. Feldman ABSTRACT A new hypothesis for the formation of the quiescent center is presented. Reported data support a mechanism for the establishment and maintenance of the quiescent center. The quiescent center is located at the most distal part of the root proper, the most...
