In dicot roots, the pericycle strengthens the roots and provides protection for the vascular bundles. In dicot root, the vascular cambium is completely secondary in origin, and it originates from a portion of pericycle tissue. The pericycle regulates the formation of lateral roots by rapidly dividing near the xylem elements of the root. WebAnalysis of cell length, cross-sectional area and nuclear length of pericycle cells in adventitious roots of Allium cepa L. has revealed the existence of three cell types whose topographical location is related to the vascular pattern. Cells opposite the xylem are short and narrow with an elongated nucleus. The intervening cells are also short ...

These included 23 eudicots, eight monocots, three early-diverging angiosperms and three gymnosperms. Two pterophytes were included as outgroups ( Fig. 2 ).
The pericycle regulates the formation of lateral roots by rapidly dividing near the xylem elements of the root. [2] It has been known to often be confused with other parts of the plant. However, its unique ring structure allows it to be more easily identified. Past efforts to isolate such tissue have been successful.
