WebJun 12, 2024 · However, we were still left with a near blank slate when it came to an understanding of the molecular events that are required to start from three pericycle founder cells to result in a lateral root primordium with a completely autonomous stem cell niche that completely recapitulates that of a primary root tip. Weboccurs in a few pericycle cells at the xylem pole, designated as ‘founder cells’, which retain the capacity to undergo (asymmetric) cell division higher up in the root when other cells …
WebLateral root growth occurs from primed xylem pole pericycle cells that can be specified as founder cells, but how these cells acquire the pluripotency state to initiate a root organogenesis ... The general zones of the primary root (taproot) that gives rise to eventual lateral roots are presented below from top to bottom. The most mature and developed tissue is found near the top, while the newly dividing cells are found near the bottom. Maturation Zone: Cells in this stage have developed differentiated characteristics and have completed maturation and elongation. The xylem system is seen to develop in this zone along w…
