In this study we present a polyphasic taxonomy regarding two widely distributed complexes of <i>Beauveria</i>: <i>B. asiatica</i> and <i>B. bassiana</i> s.lat. Some of the genetic groups as previously detected within both taxa were either confirmed or fused using population genomics. High levels of divergence were found between two clades in <i>B. asiatica</i> and among three clades in <i>B. bassiana</i>, supporting their subdivision as distinct species. Morphological examination focusing on the width and the length of phialides and conidia showed no difference among the clades within <i>B. bassiana</i> while conidial length was significantly different among clades within <i>B. asiatica</i>. The secondary metabolite profiles obtained by liquid chromatography-mass spectrometry (LC-MS) allowed a distinction between <i>B. asiatica</i> and <i>B. bassiana</i>, but not between the clades therein. Based on these genomic, morphological, chemical data, we proposed a clade of <i>B. asiatica</i> as a new species, named <i>B. thailandica</i>, and two clades of <i>B. bassiana</i> to respectively represent <i>B. namnaoensis</i> and <i>B. neobassiana</i> spp. nov. Such closely related but divergent species with different host ranges have potential to elucidate the evolution of host specificity, with potential biocontrol application. <b>Citation</b>: Kobmoo N, Arnamnart N, Pootakham W, et al. 2021.

Genome sequences revealed that three strains thought to be hybrids between <i>P. nodorum</i> and <i>P. pseudonodorum</i> were not actually hybrids, but rather represented rare gene introgressions between those species. Our data are consistent with the hypothesis that <i>P. nodorum</i> originated as a pathogen of wild grasses in the Fertile Crescent, then emerged as a wheat pathogen via host-tracking during the domestication of wheat in the same region. The discovery of a diverse array of <i>Parastagonospora</i> species infecting wheat in Iran suggests that new wheat pathogens could emerge from this region in the future. <b>Citation</b>: Croll D, Crous PW, Pereira D, et al. 2021.

The morphology of the strains was reminiscent of the genus <i>Collophorina</i>: all strains produced aseptate conidia on integrated conidiogenous cells directly on hyphae, on discrete phialides, adelophialides and by microcyclic conidiation, while in some strains additionally endoconidia or conidia in conidiomata were observed.

Very few fungi have been reported in association with olive dieback and decline in South Africa. Many of the fungal species reported from symptomatic olive trees in other countries have broad host ranges and are known to occur on other woody host plants in the Western Cape province, the main olive production region of South Africa. This survey investigated the diversity of fungi and symptoms associated with olive dieback and decline in South Africa. Isolations were made from internal wood symptoms of 145 European and 42 wild olive trees sampled in 10 and 9 districts, respectively. A total of 99 taxa were identified among 440 fungal isolates using combinations of morphological and molecular techniques. A new species of <i>Pseudophaeomoniella</i>, <i>P. globosa</i>, had the highest incidence, being recovered from 42.8 % of European and 54.8 % of wild olive samples. This species was recovered from 9 of the 10 districts where European olive trees were sampled and from all districts where wild olive trees were sampled. Members of the <i>Phaeomoniellales</i> (mainly <i>P. globosa</i>) were the most prevalent fungi in five of the seven symptom types considered, the only exceptions being twig dieback, where members of the <i>Botryosphaeriaceae</i> were more common, and soft/white rot where only <i>Basidiomycota</i> were recovered. Several of the species identified are known as pathogens of olives or other woody crops either in South Africa or elsewhere in the world, including species of <i>Neofusicoccum</i>, <i>Phaeoacremonium</i>, and <i>Pleurostoma richardsiae</i>.

They occur on a wide range of hosts and have a worldwide distribution. Although several species have in the past been reported from China, the vast majority are not known from culture or DNA phylogeny. The primary aim of the present study was thus to clarify the taxonomy and phylogeny of a large collection of <i>Cytospora</i> species associated with diverse hosts in China. <i>Cytospora</i> spp. were collected in northeast, northwest, north and southwest China, indicating that the cold and dry environments favour these fungi. In this paper, we provide an assessment of 52 <i>Cytospora</i> spp. in China, focussing on 40 species represented by 88 isolates from 28 host genera. Based on a combination of morphology and a six-locus phylogeny (ITS, LSU, <i>act1</i>, <i>rpb2</i>, <i>tef1-α</i> and <i>tub2</i>), 13 new species and one new combination are introduced. The majority of the species investigated here appear to be host-specific, although further collections and pathogenicity studies will be required to confirm this conclusion.</p>","PeriodicalId":20014,"journal":{"name":"Persoonia","volume":"45 ","pages":"1-45"},"PeriodicalIF":9.1,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/a1/15/per-2020-45-1.PMC8375343.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39363516","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}
