Phylogenetic classification of arbuscular mycorrhizal fungi: new species and higher-ranking taxa in Glomeromycota and Mucoromycota (class Endogonomycetes)

MycoKeys, Journal Year: 2024, Volume and Issue: 107, P. 273 - 325

Published: Aug. 9, 2024

Arbuscular mycorrhizal (AM) fungi - Glomeromycota and Endogonomycetes comprise multiple species higher-level taxa that have remained undescribed. We propose a mixed morphology- DNA-based classification framework to promote taxonomic communication shed light into the phylogenetic structure of these ecologically essential fungi. Based on eDNA samples long reads as type materials, we describe 15 new corresponding genera (

Nomenclatural and identification pitfalls of endophytic mycota based on DNA sequence analyses of ribosomal and protein genes phylogenetic markers: A taxonomic dead end?

Mycosphere, Journal Year: 2017, Volume and Issue: 8(10), P. 1802 - 1817

Fungal endophytes are considered ecologically important microorganisms, but their role is the subject of much speculation and methods approaches by which detected identified give rather different results.In this study, we isolated a specific endophyte from traditional medicinal plant investigated its phylogenetic relationships with other known fungi.Microscopic examination cultural details strain documented, these did not provide adequate data to substantially identify species, either genus or species level.To overcome limitation, six gene regions (SSU, LSU, ITS, TEF, RBP2 & β-Tubulin) were amplified, sequenced analysed phylogenetically (either in individual concatenated datasets) investigate placement at taxonomic ranks.Results obtained morphology insufficient species.DNA sequence analyses single combined analyses) revealed that belongs order Pleosporales, class Dothideomycetes.However, an accurate establishment generic even familial position unresolved problems associated our current system assigning particular rank discussed.

Sequence-based nomenclature: a reply to Thines et al. and Zamora et al. and provisions for an amended proposal “from the floor” to allow DNA sequences as types of names

IMA Fungus, Journal Year: 2018, Volume and Issue: 9(1), P. 185 - 198

Published: June 1, 2018

We reply to two recently published, multi-authored opinion papers by opponents of sequence-based nomenclature, namely Zamora et al. (IMA Fungus 9: 167–175, 2018) and Thines 177–183, 2018). While we agree with some the principal arguments brought forward these authors, address misconceptions demonstrate that presumed evidence presented in has been wrongly interpreted. disagree allowing sequences as types would fundamentally alter nature types, since a similar abstracted features type is already allowed Code (Art. 40.5), an illustration. also there high risk introducing artifactual taxa, this can be quantified at well below 5 %, considering various high-throughput sequencing errors. Contrary apparently widespread misconceptions, nomenclature cannot based on similarity-derived OTUs their consensus sequences, but must derived from rigorous, multiple alignment-based phylogenetic methods quantitative, single-marker species recognition algorithms, using original sequence reads; it therefore identical its approach studies physical Code. recognize limitations ITS single fungal barcoding marker, point out result conservative approach, 'false negatives" surpassing "false positives"; desirable feature nomenclature. Sequence-based does not aim accurately resolving species, naming represent unknown lineages so serve means communication, ending untenable situation exponentially growing number unlabeled fill online repositories. The risks are outweighed gains obtained reference library named spanning full array diversity. Finally, elaborate provisions addition our proposal amend take care issues approach. In particular, taking up idea Candidatus status invalid, provisional names prokaryote propose compromise allow valid publication voucherless, consistent manner, obligate designation "nom. seq." (nomen sequentiae). Such have priority over specimen- or culture-based unless either epitypified adopted for protection recommendation committee International Commission Taxonomy Fungi following evaluation strict quality control underlying established rules recommendations.
