GO:0009842 ! cyanelle definition

[gocentral]

Current def:

Plastid type found in Glaucophyta having unstacked thylakoid membranes bearing phycobilisomes; cyanelles are bound by a double membrane and a peptidoglycan layer. [source: ISBN:052131687]

Issues:

* the genus of the def shouldn't say "type". Just "plastid found in...." or "a plastid which is found in..."

• Taxon should never be a differentia. "found in Glaucophyta" should be moved to the definition context. Also we should be clear as to whether we mean (a) found only in <T> (b) as sometimes seen in <T>

For now we are assuming (a) and TaxonGOLinksFile.obo contains the following:

[Term] id: GO:0009842 name: cyanelle relationship: only_in_taxon NCBITaxon:38254 ! Glaucocystophyceae

Also:

for cc_xp_self I think we can give N+S conditions

cyanelle = plastid that has_part cyanelle thylakoid cyanelle thylakoid = plastid thylakoid that has_part phycobilisome

OK, I've improved the definition.

From a quick google, it looks like (a) found only in glaucophyta holds up. (Also, I got the impression that cyanelle = plastid that has_part peptidoglycan is just as definitive as has_part cyanelle thyalkoid.)
