Fig. 2From: Characterizing selective pressures on the pathway for de novo biosynthesis of pyrimidines in yeastGene evolution within the fungal species tree. Shown is the NCBI fungal species tree annotated with inferred gene duplication and lateral transfer events following gene tree/species tree reconciliation. Duplication events marked as paralog/xenolog were ambiguous and not obviously differentiable between being a gene duplication event and a lateral transfer event. The numbered branches within the figure indicate the following duplication and lateral transfer events: 1) Branch: Fungi [URA1 – Paralog(2), URA6 – Paralog(3), URA6 – Paralog/Xenolog(3), YNK1 – Paralog, YNK1 – Paralog/Xenolog], 2) Branch: Rhizophagus irregulare [URA5/10 – Paralog], 3) Branch: Mortierella [URA7 – Paralog, YNK1 – Paralog], 4) Branch: Mucorales [URA7 – Paralog], 5) Mucorineae [URA2 – Paralog, URA7 – Paralog], 6) Branch: Rhizopus microsporus [URA1 – Paralog, URA7 – Paralog, YNK1 – Paralog], 7) Branch: Rhizopus delemar [URA2 – Paralog], 8) Branch: Encephalitozoon intestinalis [URA7 – Paralog], 9) Branch: Pucciniales [URA6 – Paralog], 10) Branch: Filobasidiella/Cryptococcus neoformans species complex [URA5/10 – Paralog(5)], 11) Branch: Ceriporiopsis [URA1 – Paralog], 12) Branch: Fomitopsis pinicola [URA7 – Paralog], 13) Branch: Paxillus involutus [YNK1 – Paralog], 14) Branch: Laccaria bicolor [URA5/10 – Paralog], 15) Branch: Taphrinomycotina [YNK1 – Xenolog], 16) Branch: Millerozyma farinosa [YNK1 – Paralog], 17) Branch: Saccharomycetacea [URA1 – Xenolog, URA5/10 – Paralog(2), URA7 – Paralog], 18) Branch: Pezizomycotina [URA3 – Paralog], 19) Pleosporineae [URA7 – Paralog], 20) Branch: Botryosphaeriaceae [URA3 – Paralog], 21) Branch: Leotiomyceta [URA3 – Paralog/Xenolog, URA7 – Paralog, URA7 – Paralog/Xenolog], 22) Branch: Blumeria graminis f. sp. Hordei DH14 [URA5/10 – Paralog], 23) Branch: Sordariomycetes [URA7 – Paralog], 24) Branch: Hypocreales [URA7 – Paralog], 25) Branch: Fusarium [URA7 – Paralog(3)], 26) Branch: Fusarium verticillioides [URA7 – Paralog], 27) Branch: Fusarium sambucinum species complex [URA7 – Paralog], 28) Branch: Fusarium oxysporum FOSC 3-a [URA7 – Paralog], 29) Branch: Fusarium oxysporum f. sp. Vasinfectum 25433 [URA7 – Paralog]. An expandable pdf version of Fig. 2 is also found within the supplementary materialsBack to article page
