What was searched

Routing: By taxonomy. The genome's taxonomy falls inside a curated family's scope; only those families were searched.
Families searched: Ascomycota:MAT

Withheld candidate loci 2

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: too few of the family's genes found (2).

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.
