Components

Component	Type	Part of / acts on	Grounding	Genes	Stoichiometry	Essential	Role
septin proteins	Protein	part of	Reviewed label only (reviewed name; no accession asserted)			ESSENTIAL	Septin GTPases that polymerize into filament bars arranged as the chlamydospore septin filament array. `GO:0032166` GO:0032166 defines the structure as arrays of septin filaments or bars.

Mechanism graphs

Chlamydospore septin-filament-array topology (ASSEMBLY)

Septin proteins form filament bars arranged as a chlamydospore septin filament array at the chlamydospore membrane during chlamydospore formation.

Discussions

INTERPRETATION (RESOLVED): Keep the chlamydospore septin filament array distinct from the generic septin filament array and other localized septin structures. GO:0032166 denotes the chlamydospore-membrane-localized child of the generic GO:0032160 septin filament array. GO:0032165 covers the parallel prospore-membrane array, whereas GO:0005940, GO:0032173, and GO:0032159 model ring-shaped, collar-shaped, and cap-shaped higher-order septin structures.
CURATION_TODO (OPEN): Resolve an exact source-neutral grounding for chlamydospore-septin-filament-array septin proteins. The initial chlamydospore septin filament array record uses a reviewed-label-only septin protein cohort rather than guessing InterPro, Pfam, or NCBIfam accessions that may not exactly delimit all septins that form chlamydospore membrane filament arrays.

Evidence

GO:0032166 Gene Ontology cellular-component term for the chlamydospore septin filament array.
GO:0032160 OLS reports GO:0032160 septin filament array as the direct GO:0032166 parent.
