Pheromone-receptor arrays

Receptor arrays occur for both mating and non-mating STE3-like receptors (the study found arrays holding paralogs beside the mating receptors in Coprinopsis cinerea and Schizophyllum commune), so array membership does not establish that a locus is a mating receptor. receptor_array_support is a flag on the evidence behind an array; it never changes a call, its confidence or its verification label. receptor_cassette_* fields describe pheromone-precursor cassette structure (2 or more strict-CAAX ORFs within 5 kb of a receptor locus; class C when that many of those ORFs also carry tblastn precursor homology). They are descriptive only: the CAAX scan is also what admits a PR call, so cassettes are circular as confirmation; own-species curated precursors are a self-hit for class C; tandem receptors may be merged into one locus. They never change a call, tier, label, confidence or count.

Withheld candidate loci 37

Places with some MAT-gene evidence that did not pass a quality gate. Most genomes have several. They are listed so a known locus can be checked against them, not because they are likely calls.

Reasons: fewer than 2 genes could be modelled (31); too few of the family's genes found (6).

How to read this report

Idiomorph: The form of the mating-type locus a strain carries (for example MAT1-1 or MAT1-2, Plus or Minus). Basidiomycota HD and PR alleles are named after the reference they match.
High confidence: Every expected core MAT gene was found and modelled, with a conserved flanking gene where the family has one, on one contig.
Medium confidence: The core genes were found, but a gene could not be modelled, no conserved flank was found, or the locus is split (one step down).
Low confidence: A single isolated gene hit, or no core MAT gene.
Model status: Gene model: the reference protein was aligned to the genome to build the gene (exonerate, miniprot). Models differ: the two tools disagree on the structure; the alternate model is shown. Hit only: a search hit with no model, weaker evidence.
Identity: Percent amino-acid identity between the gene (or hit) and the closest reference protein.
Reference record: The curated database record whose protein matched best. Each record's metadata cites the publication or deposit it comes from.

Limits

MATPredict reads an assembly; it is not a mating assay. Two idiomorphs in one assembly can come from a homothallic species, a mixed culture or a merged diploid assembly.
Fragmented assemblies can split a locus or lose its flanking genes; an uncalled genome is weak evidence of absence.
Lineages with no curated record are searched with the whole phylum's references; family labels there are less reliable.
