Gramene mapping

Hi Anu and Pankaj,

Attached is my response to the list of Gramene terms that are unmapped to
PO. There are very few terms that need to be introduced to PO, others are
either subcellular structures, developmental stages terms, obsoleted terms
that could be mapped to the existing PO terms, or terms that already have
corresponding term in PO (though under different term name).

Bottom line here is that we do not want to loose any annotation in
Gramene, TAIR or Maize GDB. So, that's why I asked you earlier today for a
list of Gramene terms that already have annotations associated to them.
We don't have to introduce every term from Gramene and TAIR to PO. I think
we all agreed back in January in San Diego and said " We do need to go
down to granularity to allow species-specific annotation" (quoted from the
minutes).  However, we also said that not all species-specific terms would
need to be introduced to the PO.

Could you send me the list of Gramene terms 'with current annotations'? We
can start from there and go up to include terms that are needed in near
future for annotation purposes.

Attached is your list of terms with my comments in red italic font.
Underlined are 'problematic terms'(in my humble opinion). I may have
omitted comments to some terms, since I commented only the most obvious.
Once you guys 'weed the list out', it will be easier to talk about terms
that need to be introduced in PO.

Greetings,

Katica
