Root node question

[Katica Ilic]

Hello all,

I have a question regarding the root node that I have been working on
lately. There are few terms that I have hard time finding proper place
within the node, since they are not exactly anatomy terms in a strict
sense, which is why they are referred as developmental stages in Benfey's
lab (see Science, 12 Dec 2003, vol. 203:1956). These terms are,
meristematic zone, elongation zone, specialization zone, maturation zone,
and additional transition zone (in root apices of maize and grasses, at
least). In the paper above, for instance, stele node has all four zones,
endodermis plus cortex have all four zones, and so the epidermis. This is
of course very redundant, however, looking at TAIR and cereal anatomy
ontology, I couldn't really come up with the good solution that would
eliminate such redundancy. Since these terms refer to the regions of
differentiation, I don't think that they necessarily belong to
developmental stages ontology.

I would appreciate if we could talk about this tomorrow morning.

Best regards,

Katica
