Acceptance of the minutes from the POC_Conf._Call_2-22-11?
Report from the Phenotype Ontology RCN Summit
February 25-27, 2010 at the National Evolutionary Synthesis Center in Durham, NC,
Laurel and Pankaj will be attending.
From RW: -What is official PO strategy for dealing with phenotypes?
-Should it differ between description of mutant phenotypes and descriptions needed for systematic studies?
-Should PO develop a list of terms to be submitted to PATO (rather than our current piecemeal suggestions)?
-Possible case study: description of inflorescence types.
Physco terms
Term requested by MO that are already in PO but need some work
epidermis (PO:0005679)
Current def: A portion of plant tissue composed of epidermal cells that develops from the protoderm and covers the surface of a plant structure. [source: POC:curators].
Comment: The epidermis can be composed of one or more layers of cells. In some species, the epidermis is replaced by periderm. Epidermis can also include trichomes and stomatal pores (add root hairs and rhizoids too).
Is there a protoderm in non-vascular plants? (def: A portion of meristem tissue that develops from the outer layer of an apical meristem and gives rise to a portion of epidermis.)
phyllid base and phyllid apex
We already have the terms leaf base (PO:0020040) and leaf apex (PO:0020137). The choice is to make phyllid base (=non-vascular leaf base) and phyllid apex (=non-vascular leaf apex) synonyms of these terms, or to make them is_a children (see discussion of part_of children of leaf, above).
The same issue also applies for phyllid trichome/leaf trichome.
spore capsule
We have the term moss capsule (PO:0025232), but having a taxon name in the term name is not desirable, nor is having it defined based on its taxa. Suggest renaming it spore capsule and defining it based on its unique characteristics.
Current definition: A sporangium in mosses.
Proposed def.: A sporangium...
Comment: Found in mosses.
transfer cell
We have the term transfer cell (PO:0000078). Def: A cell with wall ingrowths (or invaginations) that increase the surface of the plasmalemma. [source: ISBN:0471245208] Comment: Appears to be specialized for short-distance transfer of solutes.
MO suggested definition: Specialized cell at the junction of the gametophyte and sporophyte that function in nourishing the sporophyte. [source: Bill and Nancy Malcolm (2006): Mosses and other Bryophytes, an illustrated glossary, second edition]
Are transfer cells always at the junction between the sporophyte and gametophyte? Do we want to include that in the definition or in a comment?
Do we want to add a specialized term for transfer cells in mosses? Are they different from other transfer cells?
Basal endosperm transfer cell (PO:0009018) is currently the only is_a child of transfer cell.
Upcoming meetings 2011:
* ICBO 2011 Second International Conference on Biomedical Ontology July 26-30, 2011 Buffalo, New York
CALL FOR WORKSHOP AND TUTORIAL PROPOSALS: Melissa, Alan and Chris are organizing an anatomy ontology workshop.
- LC will attend and represent the PO. Invite other plant people?
-BS suggested we might want to submit a short paper which could be published in longer form later- see above
* International Botanical Congress (IBC2011)
July 23rd-30th 2011, Melbourne, Australia
Registration is open Important dates
Symposium proposal was accepted, 'Bio-Ontologies for the Plant Sciences' under the Genetics, Genomics and Bioinformatics theme.
