New terms in PO, stolon and nodule

[Katica Ilic]

Hi All,

As a response to a user's request, I am proposing two new terms in
the Plant Structure Ontology, term 'stolon' and term 'nodule'.

Term: stolon (synonym runner)
In the ontology structure, to be placed under 'stem' node:
Stem
 (i) stolon

Proposed definition: A slender, prostrate or trailing above-ground stem
which produces roots and sometimes erect shoots at its nodes.
 (from APWeb, URL:http://www.mobot.org/MOBOT/research/APweb/)

Term: nodule
In the ontology structure, to be placed under 'root' node.
Root
(p) nodule
Proposed definition: Enlargement or swelling on the roots of plants,
particularly in the Fabaceae, inhabited by nitrogen-fixing bacteria. (from
K Esau).

Thanks,

Katica
