Version 0.1: Announced to the fission yeast community on August 4, 2025, at the 12th International Fission Yeasts Meeting (Pombe2025) in Boston.
Version 0.2: Released on September 2, 2025. Changes from version 0.1 include:
Now uses a single SOG table as the entry point, and each SOG has its own SOG page.
Downloadable nucleotide sequences of CDSs and their 1-kb flanking regions are now provided on the SOG page.
Version 1.0: Released on December 30, 2025. Changes from version 0.2 include:
Improved orthogroup inference: Revised clustering workflow that integrates OrthoFinder as the primary tool, with refinement using Proteinortho and PomBase-curated S. pombe ~ S. japonicus orthology to enhance orthogroup accuracy and sensitivity.
Removal of several poorly supported SOGs.
Continuity of SOG IDs: IDs ≤ 5400 are retained from v0.2; new SOGs (IDs > 5400) were added in this release.
The SOG table is sorted by the genomic order of S. pombe genes within each OrthoGroup; SOGs lacking an S. pombe member are sorted in descending order by the number of genes within the OrthoGroup.
Addition of a plot showing the chromosomal locations of genes belonging to an SOG on each SOG page.
Addition of an alignment featuring the orthologs from humans and Saccharomyces cerevisiae on the alignment page.
