[Ontology-editors] Fwd: discussion of sporulation terms

[Jane Lomax]

Hi Debby - yes, I don't seem to be on the PAMGO mailing list any more 
for some reason. I've cc'ed Brett Tyler from PAMGO for more specialist 
input on this (Brett, perhaps you could cc the PAMGO list?).

So the multicellular in the proposed new terms doesn't refer to the 
organism generating the spore, it refers to the spore itself (which is 
why the terms are actually 'multicellular or syncytial sporulation' as 
some spores are syncytical) which is why we had a problem. I should have 
included definitions to make that clear.

I'm not sure I understand the issue with 'cell differentiation ; 
GO:0030154'?

thanks,

Jane
