PomBase Chado notes

Alleles

Alleles are stored as features with SO type allele.

Allele feature have these possible featureprops:

  • allele_type - see below
  • canto_session - the Canto session ID if this allele was created in Canto
  • description - eg. "A123K", "1-159,274-372", "119->opal"
Allele types
  • nonsense_mutation
  • deletion
  • nucleotide_mutation
  • partial_amino_acid_deletion
  • other
  • partial_nucleotide_deletion
  • unrecorded
  • wild_type
  • unknown
  • amino_acid_mutation

Genotype modelling

Genotypes are stored as features with SO type genotype. allele features are part_of genotype feature via the feature_relationship table.

The expression of an allele is stored as a feature_relationshipprop of the part_of relation.

Genotype/phenotype annotation

Phenotypes are annotated to genotypes via the feature_cvterm table

Annotation extensions

See the GMOD extension docs for an overview.

We store extensions using a post-composed terms in the cv "PomBase annotation extension terms". The new term names have the form " []  ...". eg. "O-phospho-L-threonine [absent_during] mitotic G1 phase". There may be multiple extensions:

  • "kinetochore [during] mitotic cell cycle [during] meiotic cell cycle"
  • "cell pole [dependent_on] actin cytoskeleton [occurs_during] mitosis [occurs_during] mitotic interphase"

The relation objects can be terms (as in the examples above) or can be genes as with localizes() here:

  • "medial cortical node [localizes] SPAC57A10.02 [during] G2 phase"
