The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants.
[citation needed] In angiosperms certain molecules within the endodermis and the surrounding vasculature are sent to the pericycle which promotes the growth of the root meristems.
[citation needed] The pericycle is located between the endodermis and phloem in plant roots.
In dicot stems, it is situated around the ring of vascular bundles in the stele.
[citation needed] Past efforts to isolate such tissue have been successful.
