The accumulation of auxin triggers the LR founder cells with nuclei migration, asymmetric cell division, and formation of LRP. The auxin maximum induces the division and differentiation of the LRP and forms an LR apical meristem. third monitor not detected hp

"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 " - Pericycle founder cells
