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
2番茄红素热处理异构化方法研究显示文摘番茄红素在受热的情况下会发生反式异构体(all-trans)向顺式异构体(cis-isomers)的转化。本文研究了乙酸乙酯热回流、微波法及超声-微波协同法对番茄红素异构化的影响。结果表明:乙酸乙酯热回流处理后,6%番茄红素油树脂中顺式异构体占比高于90%番茄红素中顺式异构体占比;氮气保护对番茄红素的异构化无明显保护作用;微波对番茄红素异构化有较强的促进作用,处理5 h后顺式占比可以高达54.7%,但超声-微波协同法对番茄红素异构化的影响与微波单独使用时无明显变化。所以微波是较好的番茄红素热处理异构化方法。张环伟 Kessy N.Honest 蒋雅美 张连富 2011天然产物研究与开发2011,23,5:6

5Identifying the ‘unidentified’ fungi: a global-scale long-read third-generation sequencing approach显示文摘Molecular identification methods,in particular high-throughput sequencing tools,have greatly improved our knowledge about fungal diversity and biogeography,but many of the recovered taxa from natural environments cannot be identified to species or even higher taxonomic levels.This study addresses the phylogenetic placement of previously unrecognized fungal groups by using two complementary approaches:(i)third-generation amplicon sequencing analysis of DNA from global soil samples,screening out ITS reads of<90%similarity to other available Sanger sequences,and(ii)analysis of common fungal taxa that were previously indicated to be enigmatic in terms of taxonomic placement based on the ITS sequences alone(so-called top50 sequences).For the global soil samples,we chose to amplify the full rRNA gene operon using four partly overlapping amplicons and multiple newly developed primers or primer combinations that cover nearly all fungi and a vast majority of non-fungal eukaryotes.We extracted the rRNA 18S(SSU)and 28S(LSU)genes and performed phylogenetic analyses against carefully selected reference material.Both SSU and LSU analyses placed most soil sequences and top50 sequences to known orders and classes,but tens of monophyletic groups and single sequences remained outside described taxa.Furthermore,the LSU analyses recovered a few small groups of sequences that may potentially represent novel phyla.We conclude that rRNA genes-based phylogenetic analyses are efficient tools for determining phylogenetic relationships of fungal taxa that cannot be placed to any order or class using ITS sequences alone.However,in many instances,longer rRNA gene sequences and availability of both SSU and LSU reads are needed to improve taxonomic resolution.By leveraging third-generation sequencing from global soil samples,we successfully provided phylogenetic placement for many previously unidentified sequences and broadened our view on the fungal tree of life,with 10-20%new order-level taxa.In addition,the PacBio sequence data greatly extends fungal class-level information in reference databases.Leho Tedersoo Sten Anslan Mohammad Bahram Urmas Kõljalg Kessy Abarenkov 2020Fungal Diversity2020,,4:2
