Feedback on POC: granular terms under 'petiole' (PR#56)

[Katica Ilic]

Dear Ruth,

Thanks for the feedback and suggestion for improving current Plant Ontology
structure. Term 'petiole' does not have any granular 'children' terms yet, since
we deliberately chose not to have very detailed and elaborate ontology, at least
not in the initial stage when we were focused on creating a robust and
extensible structure as a backbone to which granular terms can be added as
needed. 

Our group is now considering your suggestion for adding more granular terms for
'petiole', and I have a couple of questions, to make sure that we can
accommodate what you would like to see in this segment of the ontology, at the
same time, making sure that we keep the Plant Ontology 'generic', encompassing
both, dicots and monocots. I am assuming that these terms are required for
functional genomics project that you might be involved and I wonder if a simpler
solution that does not have, for instance 'interfascicular parenchyma' would
work. I'll get back to you soon with the outline of the structure we are
currently considering, but in the meantime, it would be useful if you can tell
us few fords about the specific reasons for inquiring the structure you proposed
and also how you use the Plant Ontology.

Thank you again for sending us your suggestion. I look forward to hearing from
you.

Best regards,

Katica Ilic, POC Project Coordinator

> cular bundles (xylem and phloem) are separated by this interfascicular pare=
