1High-level classification of the Fungi and a tool for evolutionary ecological analyses显示文摘High-throughput sequencing studies generate vast amounts of taxonomic data.Evolutionary ecological hypotheses of the recovered taxa and Species Hypotheses are difficult to test due to problems with alignments and the lack of a phylogenetic backbone.We propose an updated phylum-and class-level fungal classification accounting for monophyly and divergence time so that the main taxonomic ranks are more informative.Based on phylogenies and divergence time estimates,we adopt phylum rank to Aphelidiomycota,Basidiobolomycota,Calcarisporiellomycota,Glomeromycota,Entomophthoromycota,Entorrhizomycota,Kickxellomycota,Monoblepharomycota,Mortierellomycota and Olpidiomycota.We accept nine subkingdoms to accommodate these 18 phyla.We consider the kingdom Nucleariae(phyla Nuclearida and Fonticulida)as a sister group to the Fungi.We also introduce a perl script and a newick-formatted classification backbone for assigning Species Hypotheses into a hierarchical taxonomic framework,using this or any other classification system.We provide an example of testing evolutionary ecological hypotheses based on a global soil fungal data set.Leho Tedersoo Santiago Sanchez-Ramırez Urmas Koljalg Mohammad Bahram Markus Doring Dmitry Schigel Tom May Martin Ryberg Kessy Abarenkov 2018Fungal Diversity2018,,3:7
2Ranking higher taxa using divergence times:a case study in Dothideomycetes显示文摘The current classification system for the recognition of taxonomic ranks among fungi,especially at highranking level,is subjective.With the development of molecular approaches and the availability of fossil calibration data,the use of divergence times as a universally standardized criterion for ranking taxa has now become possible.We can therefore date the origin of Ascomycota lineages by using molecular clock methods and establish the divergence times for the orders and families of Dothideomycetes.We chose Dothideomycetes,the largest class of the phylum Ascomycota,which contains 32 orders,to establish ages at which points orders have split;and Pleosporales,the largest order of Dothideomycetes with 55 families,to establish family divergence times.We have assembled a multi-gene data set(LSU,SSU,TEF1 and RPB2)from 391 taxa representing most family groups of Dothideomycetes and utilized fossil calibration points solely from within the ascomycetes and a Bayesian approach to establish divergence times of Dothideomycetes lineages.Two separated datasets were analysed:(i)272 taxa representing 32 orders of Dothideomycetes were included for the order level analysis,and(ii)191 taxa representing 55 families of Pleosporales were included for the family level analysis.Our results indicate that divergence times(crown age)for most orders(20 out of 32,or 63%)are between 100 and 220 Mya,while divergence times for most families(39 out of 55,or 71%)are between 20 and 100 Mya.We believe that divergence times can provide additional evidence to support establishment of higher level taxa,such as families,orders and classes.Taking advantage of this added approach,we can strive towards establishing a standardized taxonomic system both within and outside Fungi.In this study we found that molecular dating coupled with phylogenetic inferences provides no support for the taxonomic status of two currently recognized orders,namely Bezerromycetales and Wiesneriomycetales and these are treated as synonyms of Tubeufiales while Asterotexiales is treated as a synonym of Asterinales.In addition,we provide an updated phylogenetic assessment of Dothideomycetes previously published as the Families of Dothideomycetes in 2013 with a further ten orders and 35 families.Jian-Kui Liu Kevin D.Hyde Rajesh Jeewon Alan J.L.Phillips Sajeewa S.N.Maharachchikumbura Martin Ryberg Zuo-Yi Liu Qi Zhao 2017Fungal Diversity2017,,3:3
3Safety and efficacy of Profermin~to induce remission in ulcerative colitis显示文摘AIM:To test the efficacy and safety of Profermin in inducing remission in patients with active ulcerative colitis(UC).METHODS:The study included 39 patients with mild to moderate UC defined as a Simple Clinical Colitis Activity Index(SCCAI)>4 and<12(median:7.5),who were treated open-label with Profermintwice daily for 24 wk.Daily SCCAI was reported observer blinded via the Internet.RESULTS:In an intention to treat(ITT)analysis,the mean reduction in SCCAI score was 56.5%.Of the 39 patients,24(62%)reached the primary endpoint,which was proportion of patients with≥50%reduction in SCCAI.Our secondary endpoint,the proportion of patients in remission defined as SCCAI≤2.5,was in ITT analysis reached in 18 of the 39 patients(46%).In a repeated-measure regression analysis,the estimated mean reduction in score was 5.0 points(95%CI:4.1-5.9,P<0.001)and the estimated mean time taken to obtain half the reduction in score was 28 d(95%CI:26-30).There were no serious adverse events(AEs)or withdrawals due to AEs.Profermin was generally well tolerated.CONCLUSION:Profermin is safe and may be effective in inducing remission of active UC.Aleksander Krag Hans Israelsen Bjrn von Ryberg Klaus K Andersen Flemming Bendtsen 2012World Journal of Gastroenterology2012,18,15:2
