WebMay 18, 2024 · The increase in auxin at the xylem pole initiates a transcriptional programme that specifies lateral root founder cells in Arabidopsis. Early founder cells in the xylem pole pericycle... WebFeb 14, 2013 · Organ primordia develop from populations of founder cell into organs through the coordinated process of cell division and differentiation. Lateral roots (LRs) originate from a small number of differentiated pericycle cells adjacent to xylem poles, called pericycle founder cells (reviewed in [1] ).

WebHow are the lateral root founder cells specified in the pericycle to initiate lateral root development? An Aux/IAA28 signaling module activates transcription factor GATA23 to control founder cell identity. Plant … WebAug 12, 2024 · LRs originate in a tissue called the pericycle, but the underlying mechanism is obscure. With the aid of clonal analysis, we deduced that LR initiation begins with a single …
Webpericycle cells called founder cells. For cell sorting, roots were exposed to nitrate or mock (KCl) treatments for a total of 3.5 h and then isolated by FACS after a rapid enzymatic dissociation of cells (1, 2). The goal of the analysis was to gain a comprehensive view of how tissues respond individually and coordinate their responses to ... WebDec 9, 2011 · Here, I will summarize these recent advances, focusing on the prominent role of auxin and cell cycle activity, and elaborating on the three key steps of pericycle cell priming, founder cell establishment and asymmetric cell division.
WebDec 7, 2011 · Here, the pericycle cells appeared to divide both asymmetrically and symmetrically and to lack the formation of the central core of small pericycle cells at stage I (Fig. 5F). Among the 20 seedlings examined for each group of plants, the wild type had 13 central cores of pericycle cells at stage I, whereas the CLEL6 - and CLEL7 -overexpressing ... 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
