Reference species for fungi

Reference fungi data

Explanation and definition for the "reference species" we use for the course.

Many bioinformatics procedures depend on the comparison of sequences between species. To make good use of evolutionary information, we should choose species that span the breadth of observations, and that are not biased towards a particular branch of the phylogenetic tree. To keep procedures manageable, the number of species cannot be "too large". For fungi, we make use of recent phylogenetic studies that establish the branching order of the entire kingdom, and we choose ten representatives for clades at the Class or subphylum level. To illustrate the "class" level: for animals the class levels include e.g. bony and cartilaginous fishes, segmented worms, amphibians, reptiles, birds and mammals - the familiar, very broad categories. I.e. a reference species list of animals, divided along class levels, might include zebrafish, african claw frog, the fruit fly, humans, the raven, the oyster etc. etc. Even though they are all fungi, our reference species are no more similar to each other than the former.

Reference species

To select a set of diverse species, the whole set of names of genome-sequenced fungi was loaded into the NCBI's Common Taxonomic Tree tree tool. Then ten representative species were manually selected as being well distributed across the tree. The selected species are:

Name	`BICODE`	`tax ID`	Classification

Phylum Ascomycota
Aspergillus nidulans	`ASPNI`	`162425`	Subphylum Pezizomycotina; Class Eurotiomycetes
Bipolaris oryzae	`BIPOR`	`101162`	Subphylum Pezizomycotina; Class Dothideomycetes
Neurospora crassa	`NEUCR`	`5141`	Subphylum Pezizomycotina; Class Sordariomycetes
Saccharomyces cerevisiae	`SACCE`	`4932`	Subphylum Saccharomycotina
Schizosaccharomyces pombe	`SCHPO`	`4896`	Subphylum Taphrinomycotina

Phylum Basidiomyceta
Coprinopsis cinerea	`COPCI`	`5346`	Subphylum Agaricomycotina; Class Agaricomycetes
Cryptococcus neoformans	`CRYNE`	`5207`	Subphylum Agaricomycotina; Class Tremellomycetes
Puccinia Graminis	`PUCGR`	`5297`	Subphylum Pucciniomycotina
Ustilago maydis	`USTMA`	`5270`	Subphylum Ustilaginomycotina
Wallemia mellicola	`WALME`	`1708541`	Subphylum Wallemiales incertae sedis
