Unlike vegetative hyphae, fruiting bodies grow determinately and follow a genetically encoded developmental program that orchestrates their growth, tissue differentiation and sexual sporulation. In spite of more than a century of research, our understanding of the molecular details of fruiting body morphogenesis is still limited and a general synthesis on the genetics of this complex process is lacking. In this paper, we aim at a comprehensive identification of conserved genes related to fruiting body morphogenesis and distil novel functional hypotheses for functionally poorly characterised ones. As a result of this analysis, we report 921 conserved developmentally expressed gene families, only a few dozens of which have previously been reported to be involved in fruiting body development. Based on literature data, conserved expression patterns and functional annotations, we provide hypotheses on the potential role of these gene families in fruiting body development, yielding the most complete description of molecular processes in fruiting body morphogenesis to date. We discuss genes related to the initiation of fruiting, differentiation, growth, cell surface and cell wall, defence, transcriptional regulation as well as signal transduction. Based on these data we derive a general model of fruiting body development, which includes an early, proliferative phase that is mostly concerned with laying out the mushroom body plan (via cell division and differentiation), and a second phase of growth via cell expansion as well as meiotic events and sporulation. Altogether, our discussions cover 1 480 genes of <i>Coprinopsis cinerea</i>, and their orthologs in <i>Agaricus bisporus, Cyclocybe aegerita, Armillaria ostoyae, Auriculariopsis ampla, Laccaria bicolor, Lentinula edodes, Lentinus tigrinus, Mycena kentingensis, Phanerochaete chrysosporium, Pleurotus ostreatus</i>, and <i>Schizophyllum commune</i>, providing functional hypotheses for ~10 % of genes in the genomes of these species. Although experimental evidence for the role of these genes will need to be established in the future, our data provide a roadmap for guiding functional analyses of fruiting related genes in the <i>Agaricomycetes</i>. We anticipate that the gene compendium presented here, combined with developments in functional genomics approaches will contribute to uncovering the genetic bases of one of the most spectacular multicellular developmental processes in fungi. <b>Citation:</b> Nagy LG, Vonk PJ, Künzler M, Földi C, Virágh M, Ohm RA, Hennicke F, Bálint B, Csernetics Á, Hegedüs B, Hou Z, Liu XB, Nan S, M.

The <i>Saccharomycotina</i> consist of more than 1 200 known species currently divided into 16 families, one order, and one class. Species in this subphylum are ecologically and metabolically diverse and include important opportunistic human pathogens, as well as species important in biotechnological applications. Many traits of biotechnological interest are found in closely related species and often restricted to single phylogenetic clades. However, the biotechnological potential of most yeast species remains unexplored. Although the subphylum <i>Saccharomycotina</i> has much higher rates of genome sequence evolution than its sister subphylum, <i>Pezizomycotina</i>, it contains only one class compared to the 16 classes in <i>Pezizomycotina</i>. The third subphylum of <i>Ascomycota</i>, the <i>Taphrinomycotina</i>, consists of six classes and has approximately 10 times fewer species than the <i>Saccharomycotina</i>. These data indicate that the current classification of all these yeasts into a single class and a single order is an underappreciation of their diversity. Our previous genome-scale phylogenetic analyses showed that the <i>Saccharomycotina</i> contains 12 major and robustly supported phylogenetic clades; seven of these are current families (<i>Lipomycetaceae, Trigonopsidaceae, Alloascoideaceae, Pichiaceae, Phaffomycetaceae, Saccharomycodaceae</i>, and <i>Saccharomycetaceae</i>), one comprises two current families (<i>Dipodascaceae</i> and <i>Trichomonascaceae</i>), one represents the genus <i>Sporopachydermia</i>, and three represent lineages that differ in their translation of the CUG codon (CUG-Ala, CUG-Ser1, and CUG-Ser2). Using these analyses in combination with relative evolutionary divergence and genome content analyses, we propose an updated classification for the <i>Saccharomycotina</i>, including seven classes and 12 orders that can be diagnosed by genome content. This updated classification is consistent with the high levels of genomic diversity within this subphylum and is necessary to make the higher rank classification of the <i>Saccharomycotina</i> more comparable to that of other fungi, as well as to communicate efficiently on lineages that are not yet formally named. <b>Taxonomic novelties: New classes:</b> <i>Alloascoideomycetes</i> M.

Sexual morphs of <i>Clonostachys</i> spp<i>.</i> were placed in the genus <i>Bionectria</i>, which was further segregated into the six subgenera <i>Astromata</i>, <i>Bionectria</i>, <i>Epiphloea</i>, <i>Myronectria</i>, <i>Uniparietina</i>, and <i>Zebrinella</i>. However, with the end of dual nomenclature, <i>Clonostachys</i> became the single depository for sexual and asexual morph-typified species. Species of <i>Clonostachys</i> are typically characterised by penicillate, sporodochial, and, in many cases, dimorphic conidiophores (primary and secondary conidiophores). Primary conidiophores are mononematous, either verticillium-like or narrowly penicillate. The secondary conidiophores generally form imbricate conidial chains that can collapse to slimy masses, particularly on sporodochia. In the present study, we investigated the species diversity within a collection of 420 strains of <i>Clonostachys</i> from the culture collection of, and personal collections at, the Westerdijk Fungal Biodiversity Institute in Utrecht, the Netherlands. Strains were analysed based on their morphological characters and molecular phylogeny. The latter used DNA sequence data of the nuclear ribosomal internal transcribed spacer regions and intervening 5.8S nrDNA (ITS) and partial 28S large subunit (LSU) nrDNA and partial protein encoding genes including the RNA polymerase II second largest subunit (<i>RPB2</i>), translation elongation factor 1-alpha (<i>TEF1</i>) and β-tubulin (<i>TUB2</i>). Based on these results, the subgenera <i>Astromata</i>, <i>Bionectria</i>, <i>Myronectria</i> and <i>Zebrinella</i> are supported within <i>Clonostachys</i>. Furthermore, the genus <i>Sesquicillium</i> is resurrected to accommodate the former subgenera <i>Epiphloea</i> and <i>Uniparietina</i>. The close relationship of <i>Clonostachys</i> and <i>Sesquicillium</i> is strongly supported as both are inferred phylogenetically as sister-genera. New taxa include 24 new species and 10 new combinations. Recognition of <i>Sesquicillium</i> distinguishes species typically forming a reduced perithecial stroma superficially on plant tissue from species in <i>Clonostachys</i> often forming well-developed, through bark erumpent stromata. The patterns of observed perithecial wall anatomies, perithecial wall and stroma interfaces, and asexual morph diversifications described in a previously compiled monograph are used for interpreting ancestral state reconstructions. It is inferred that the common ancestor of <i>Clonostachys</i> and <i>Sesquicillium</i> may have formed perithecia superficially on leaves, possessed a perithecial wall consisting of a single region, and formed intercalary phialides in penicilli of conidiophores.

Species of this genus are extensively exploited in industrial, commercial, pharmaceutical, and biocontrol applications, and proved to be a rich source of novel and bioactive secondary metabolites. <i>Acremonium</i> has been recognised as a taxonomically difficult group of ascomycetes, due to the reduced and high plasticity of morphological characters, wide ecological distribution and substrate range. Recent advances in molecular phylogenies, revealed that <i>Acremonium</i> is highly polyphyletic and members of <i>Acremonium</i> <i>s. lat.</i> belong to at least three distinct orders of <i>Sordariomycetes</i>, of which numerous orders, families and genera with acremonium-like morphs remain undefined. To infer the phylogenetic relationships and establish a natural classification for acremonium-like taxa, systematic analyses were conducted based on a large number of cultures with a global distribution and varied substrates. A total of 633 cultures with acremonium-like morphology, including 261 ex-type cultures from 89 countries and a variety of substrates including soil, plants, fungi, humans, insects, air, and water were examined. An overview phylogenetic tree based on three loci (ITS, LSU, <i>rpb2</i>) was generated to delimit the orders and families. Separate trees based on a combined analysis of four loci (ITS, LSU, <i>rpb2</i>, <i>tef-1α</i>) were used to delimit species at generic and family levels. Combined with the morphological features, host associations and ecological analyses, acremonium-like species evaluated in the present study are currently assigned to 63 genera, and 14 families in <i>Cephalothecales,</i> <i>Glomerellales</i> and <i>Hypocreales</i>, mainly in the families <i>Bionectriaceae</i>, <i>Plectosphaerellaceae</i> and <i>Sarocladiaceae</i> and five new hypocrealean families, namely <i>Chrysonectriaceae</i>, <i>Neoacremoniaceae</i>, <i>Nothoacremoniaceae</i>, <i>Pseudoniessliaceae</i> and <i>Valsonectriaceae</i>.

From these, a total of 213 strains were selected for the final analysis according to their calmodulin (&lt;i&gt;CaM&lt;/i&gt;) genotype, substrate and geography. This set was used for phylogenetic analysis based on five loci (&lt;i&gt;benA&lt;/i&gt;, &lt;i&gt;CaM&lt;/i&gt;, &lt;i&gt;RPB2&lt;/i&gt;, &lt;i&gt;Mcm7&lt;/i&gt;, &lt;i&gt;Tsr1&lt;/i&gt;). Apart from the classical phylogenetic methods, we used multispecies coalescence (MSC) model-based methods, including one multilocus method (STACEY) and five single-locus methods (GMYC, bGMYC, PTP, bPTP, ABGD). Almost all species delimitation methods suggested a broad species concept with only four species consistently supported. We also demonstrated that the currently applied concept of species is not sustainable as there are incongruences between single-gene phylogenies resulting in different species identifications when using different gene regions. Morphological and physiological data showed overall lack of good, taxonomically informative characters, which could be used for identification of such a large number of existing species. The characters expressed either low variability across species or significant intraspecific variability exceeding interspecific variability. Based on the above-mentioned results, we reduce series &lt;i&gt;Versicolores&lt;/i&gt; to four species, namely &lt;i&gt;A.&lt;/i&gt; &lt;i&gt;versicolor, A. creber&lt;/i&gt;, &lt;i&gt;A. sydowii&lt;/i&gt; and &lt;i&gt;A. subversicolor&lt;/i&gt;, and the remaining species are synonymized with either &lt;i&gt;A. versicolor&lt;/i&gt; or &lt;i&gt;A. creber&lt;/i&gt;. The revised descriptions of the four accepted species are provided. They can all be identified by any of the five genes used in this study. Despite the large reduction in species number, identification based on phenotypic characters remains challenging, because the variation in phenotypic characters is high and overlapping among species, especially between &lt;i&gt;A. versicolor&lt;/i&gt; and &lt;i&gt;A. creber&lt;/i&gt;. Similar to the 17 narrowly defined species, the four broadly defined species do not have a specific ecology and are distributed worldwide. We expect that the application of comparable methodology with extensive sampling could lead to a similar reduction in the number of cryptic species in other extensively studied &lt;i&gt;Aspergillus&lt;/i&gt; species complexes and other fungal genera. &lt;b&gt;Citation:&lt;/b&gt; Sklenář F, Glässnerová K, Jurjević Ž, Houbraken J, Samson RA, Visagie CM, Yilm","PeriodicalId":22036,"journal":{"name":"Studies in Mycology","volume":null,"pages":null},"PeriodicalIF":16.5,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9903908/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9240641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
