New terms in PO

[Katica Ilic]

Hi all,

We have a user's request to introduce the following terms in PO:

Cauline leaf
Rosette leaf
Hypocotyl hook


Cauline leaf and rosette leaf are both present in TAIR (with several
annotations for both)

Term name: Cauline leaf
ID: TAIR:0000090 (currently 5 genes associated with this term, 5
annotations)
Def: Stem leaf, produced before the transition to flowering, lacking a
petiole.

Term name: Rosette leaf
ID: TAIR:0000089 (currently 11 genes associated with this term, 11
annotations)
Def: Leaf that is part of phyllotactic spiral with little internode
elongation between successive leaves. In Arabidopsis, vegetative
development is characterized by the production of the rosette leaves.

Both terms could be children of 'leaf' or 'simple leaf' (instance
of).
These are the existing terms in PO (under phyllome node), and to my
knowledge, synonymy may not work here:

  PO:0009025 : leaf
  PO:0006340 : adult leaf
  PO:0020103 : flag leaf
  PO:0020043 : compound leaf
  PO:0006338 : embryonic leaf
  PO:0006339 : juvenile leaf
  PO:0020042 : simple leaf


I myself am not very sure about the third proposed term, hypocotyl
hook; it's referring to the region of the seedling in early seedling
development, but this is not dev stage term.

There are few publications (often ethylene response genes) in which the
authors are referring to 'hypocotyl hook'. Here are some:

http://www.blackwell-synergy.com/links/doi/10.1046/j.1365-313x.1999.00607.x/full/

What do you think about introducing these three terms?

Pankaj, this node is currently assigned to you.
