Proposal for the new term in Plant Structure Ont: middle layer

[katica at acoma.Stanford.EDU]

Hi All,

This is the proposal for introduction of the new term in the Plant 
Structure Ontology, 'middle layer':

New term name: Middle layer
Definition: Usually a single cell layer between tapetum and endothecium 
which almost invariably degenerates early during angiosperm anther 
development and is eventually absorbed by adjacent cells.

Proposed ontology structure:

PO:0000002 : anther wall
(p) PO:0020002 : endothecium
(p) PO:0020004 : exothecium
(p) PO:0020005 : placentoid
(p) PO:0020101 : stomium
(p) PO:0009071 : tapetum
(p) new term: middle layer

I am planning to introduce this term to the PO a week from today, unless 
active discussion takes place regarding this term over the next week at 
po-dev mailing list. I would greatly appreciate your comments and 
suggestions.

Thanks and have a great weekend.

Katica Ilic
