Webof pericycle cells overlaying the xylem pole acquire founder cell (FC) identity and divide asymmetrically. Next, these pericycle derived initials undergo a sequence of cell divisions and differentiation events that ultimately results in the formation of an LR primordium.

WebJun 8, 2024 · Lateral root initiation is a post-embryonic process that requires the specification of a subset of pericycle cells adjacent to the xylem pole in the primary root into lateral root founder cells. The first visible event of lateral root initiation in Arabidopsis is the simultaneous migration of nuclei in neighbouring founder cells.

"WebMar 20, 2024 · Pericycle and endodermis are two types of cell layers unique to plants. Pericycle encircles the vascular tissues of roots and stem. It is the outermost cell layer of the stele. Meanwhile, endodermis surrounds the pericycle. Therefore, endodermis is the innermost cell layer of the cortex. Moreover, pericycle has one or two cell layers, while the … " - Pericycle cell types

Web(B) For indeterminate nodules, the initial cell divisions forming the nodule primordia occur in inner cortical cells, while in determinate nodules, this occurs in the outer cortical cells (C). Despite their anatomical differences, cell divisions in the pericycle have been observed in both nodule types. WebAug 12, 2024 · Xylem pole pericycle (XPP) cells continue to divide after leaving the root apical meristem (1, 2) and maintain morphogenetic potential. Before LR primordium (LRP) initiation, XPP cells become primed (3, 4) and competent to form LRs. This competence is restricted in time and space (5, 6).
