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

[kellogge]

What about putting it under germination -  "on the parent plant" vs.  
"independent of the parent", or something more or less equivalent?  The  
word "vivipary sensu plants" would then be a synonym, so if a corn  
person searched on vivipary, the term would appear.  The same thing  
happens in mangroves; the seed never goes through the dessication  
process - no increase in ABA, no accumulation of lea proteins, etc.   
Development perfectly normal, but is continuous.  And as Tom points  
out, the process is reasonably well understood.
    In vivipary as occurs in Bryophyllum and other piggy-back plants, a  
new meristem is organized on the margin of the leaf, and a little  
plantlet forms.  It's mechanistically different from mangrove and  
cereal vivipary so probably needs a different term.
