[Fwd: [ geneontology-Curator requests-929957 ] vivipary]

[David Marshall]

preharvest sprouting is of particular interest. There are a number of  advances at the molecular level. It is interesting to place preharvest sprouting in the context of related processes i.e. grain development, "normal germination", dormance and in the case of barley- malting.

	But,
	If an ontology defines "vivipary" as a "type of" preharvest sprouting
	(or vice-versa) then won't it help the corn people do comparative
	genomics with the barley people?
