Taxon constraint: GO:0043073 germ cell nucleus

[ValWood]

Please provide as much information as you can:

GO:0043073 germ cell nucleus The nucleus of a germ cell, a reproductive cell in multicellular organisms.

• Request to add a taxon constraint:
• • only in taxon:

Metazoa and plants (defined as multicellular)

• • never in taxon:

• Request to remove a taxon constraint: Please specify

• Supporting evidence if available (e.g PMID):

A bit to unpack here...

"germ cell nucleus" is such an odd level of granularity..

"germ cell" as defined in GO and CL encompasses plants and I believe plasmodium, some fungi, ...

We should put the TCs at the most parsimonious places along the chain:

germ cell nucleus -> germ cell -> fertilization -> sexual reproduction

I think there is a long confusing history of what is meant by gamete/zygote/fertilization in GO, e.g from 2007:

right, in fungi a germ cell is a spore.
