#25 New term: Pulvinus

Dear Chih-Wei,

Looking to link the legacy MaizeGDB anatomy terms not yet used for annotation at MaizeGDB, to an accession in PO I need some help with 'pulvinus'. Is it simply part of the node?

Discussion about Dec 2004 indicated this was part of ‘node’ - do you know if that is considered appropriate for now? If so, should we add pulvinus in the definition or comment part of the term?

Hi Chih-Wei,

Please have a look at this discussion from PO archives.

From Toby Kellogg:
Hi Mary -
Pulvinus is generally a thickened structure of a stem or leaf that is often involved in movement. There probably needs to be a general term (pulvinus - is_a plant structure) with a couple of children - pulvinus of petiole (found in many legumes, among others), and pulvinus of inflorescence branch (found in many grasses). I think it probably should not be part of node, since it's not clear what it's a part of. Bob Schmidt has isolated some inflorescence mutations that lack the pulvinus, and they are just trying to characterize the pulvinus and those mutants in particular.
