Pericycle

Pericycle

The pericycle is a cylinder of parenchyma cells that lies just inside the endodermis and is the outer most part of the stele (biology) of plants.

In dicots, it also has the capacity to produce lateral roots. Branch roots arise from this primary meristem tissue. In plants undergoing secondary growth, the pericycle contributes to the vascular cambium often diverging into a cork cambium.

A plant tissue characteristic of the roots, located between the endodermis and phloem.

It may be of single layer or it may be multilayered.

Past efforts to isolate such tissue have been successful.
