pericycle

[Pankaj Jaiswal]

Hi,
Here is what I proposed in response to Alison's mail for pericycle

---PO:0009075 : plant ontology
----i PO:0009011 : plant structure
-------i PO:0009003 : sporophyte
-----------p PO:0009005 : root
--------------p PO:0000258 : root cortex
--------------p PO:0020124 : root stele
-------------------p PO:0006203 : pericycle
-------i PO:0009007 : tissue
-----------i PO:0005708 : cortex
--------------i PO:0000258 : root cortex
--------------i PO:0006203 : pericycle

But this is again leading us into a black hole, which we are trying to
avoid. The term pericycle is a generic term and we need to create its
instances such as
-root pericycle
-stem pericycle
-leaf pericycle

In order to make correct lineage the instantiation is required.

Current definition and comments sauugest it so..

# Definition:

     * Part of the tissue of the stele located between the phloem and
endodermis.

# Comment:

     * In seed plants it is regularly present in roots and absent in
most stems and leaves.
