Although some taxonomic confusion in the family has been clarifed, rDNA data alone is unable to resolve higher level phylogenetic relationships within Mortierellaceae. In this study, we applied two parallel approaches to resolve the Mortierel- laceae phylogeny: low coverage genome (LCG) sequencing and high-throughput, multiplexed targeted amplicon sequenc- ing to generate sequence data for multi-gene phylogenetics. We then combined our datasets to provide a well-supported genome-based phylogeny having broad sampling depth from the amplicon dataset. Resolving the Mortierellaceae phylogeny into monophyletic genera resulted in 13 genera, 7 of which are newly proposed. Low-coverage genome sequencing proved to be a relatively cost-efective means of generating a high-confdence phylogeny. -

Received 10 March, 2015; Accepted 5 May, 2015 The objective of this study was to characterize the diversity of arbuscular mycorrhizal fungal (AMF) communities colonizing the roots of Vigna unguiculata (L.) plants cultivated in two different sites in Senegal. Roots of cowpea plants and soil samples were collected from two fields (Ngothie and Diokoul) in the rural community of Dya (Senegal). Microscopic observations of the stained roots indicated a high colonization rate in roots from Ngothie site as compared to those from Diokoul site. The partial small subunit of ribosomal DNA genes was amplified from the genomic DNA extracted from these roots by polymerase chain reaction (PCR) with the universal primer NS31 and a fungal-specific primer AML2. Nucleotide sequence analysis revealed that 22 sequences from Ngothie site and only four sequences from Diokoul site were close to those of known arbuscular mycorrhizal fungi. -
The Phylogeny of Plant and Animal Pathogens in the Ascomycota
Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus. -

In the present study, 90 type and reference strains were used to infer a comprehensive phylogeny of Mortierellales from the sequence data of the complete ITS region and the LSU and SSU genes with a special attention to the monophyly of the genus Mortierella. Out of 15 alternative partitioning strategies compared on the basis of Bayes factors, the one with the highest number of partitions was found optimal (with mixture models yielding the best likelihood and tree length values), implying a higher complexity of evolutionary patterns in the ribosomal genes than generally recognized. Modeling the ITS1, 5.8S, and ITS2, loci separately improved model fit significantly as compared to treating all as one and the same partition. -

On the Safety of Mortierella Alpina for the Production of Food Ingredients, Such As Arachidonic Acid
Journal of Biotechnology 56 (1997) 153–165 Review On the safety of Mortierella alpina for the production of food ingredients, such as arachidonic acid Hugo Streekstra * Gist-brocades B.V., Corporate New Business De6elopment, P.O. Box 1, 2600 MA Delft, Netherlands Received 22 July 1996; accepted 23 May 1997 Abstract Mortierella alpina is the most efficient production organism for arachidonic acid (AA) presently known. Since AA is being developed as a food ingredient, and since M. alpina has no history of use for such applications, we have undertaken this safety evaluation. M. alpina is a common soil fungus, to which humans are frequently exposed. The production strains are non-pathogenic and do not form potentially allergenic spores under production conditions. Moreover, there are no reliable reports in the literature connecting the species with disease or allergenic responses. No production of mycotoxins was observed, in line with the absence of literature reports describing such products, and with the results of toxicological tests. On solid growth media the strains showed antibiotic activity against Gram-positive bacteria. In submerged culture, which is used for AA production, no significant antibiotic activity was found. We conclude that M. alpina in general, and the AA production strains CBS 168.95 and CBS 169.95 in particular, should be considered safe for the submerged production of food ingredients. © 1997 Elsevier Science B.V.

Mortierellaceae Phylogenomics and Tripartite Plant-Fungal-Bacterial Symbiosis of Mortierella Elongata
MORTIERELLACEAE PHYLOGENOMICS AND TRIPARTITE PLANT-FUNGAL-BACTERIAL SYMBIOSIS OF MORTIERELLA ELONGATA By Natalie Vandepol A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Microbiology & Molecular Genetics – Doctor of Philosophy 2020 ABSTRACT MORTIERELLACEAE PHYLOGENOMICS AND TRIPARTITE PLANT-FUNGAL-BACTERIAL SYMBIOSIS OF MORTIERELLA ELONGATA By Natalie Vandepol Microbial promotion of plant growth has great potential to improve agricultural yields and protect plants against pathogens and/or abiotic stresses. Soil fungi in Mortierellaceae are non- mycorrhizal plant associates that frequently harbor bacterial endosymbionts. My research focused on resolving the Mortierellaceae phylogeny and on characterizing the effect of Mortierella elongata and its bacterial symbionts on Arabidopsis thaliana growth and molecular functioning. Early efforts to classify Mortierellaceae were based on morphology, but phylogenetic studies with ribosomal DNA (rDNA) markers have demonstrated conflicting taxonomic groupings and polyphyletic genera. In this study, I applied two approaches: low coverage genome (LCG) sequencing and high-throughput targeted amplicon sequencing to generate multi-locus sequence data. I combined these datasets to generate a well-supported genome-based phylogeny having broad sampling depth from the amplicon dataset. Resolving the Mortierellaceae phylogeny into monophyletic groups led to the definition of 14 genera, 7 of which are newly proposed. Mortierellaceae are broadly considered plant associates, but the underlying mechanisms of association are not well understood. In this study, I focused on the symbiosis between M. elongata, its endobacteria, and A. thaliana. I measured aerial plant growth and seed production and used transcriptomics to characterize differentially expressed plant genes (DEGs) while varying fungal treatments. M. elongata was shown to promote aerial plant growth and affect seed production independent of endobacteria. -

(2018): Microscopic fungi on ca- davers and skeletons from cave and mine environments. – Czech Mycol. 70(2): 101–121. During long-term studies of microscopic fungi in 80 European caves and mine environments many cadavers and skeletons of animals inhabiting these environments and various animal visitors were found, some of them with visible microfungal growth. Direct isolation, the dilution plate method and various types of isolation media were used. The resulting spectrum of isolated fungi is presented and compared with records about their previous isolation. Compared to former studies focused mainly on bat mycobiota, this paper contributes to a wider knowledge of fungal assemblages colonising various animal bodies in underground environments. The most interesting findings include ascocarps of Acaulium caviariforme found abundant on mam- mals cadavers, while Botryosporium longibrachiatum isolated from frogs, Chaetocladium jonesiae from bats and Penicillium vulpinum from spiders represent the first records of these species from cadavers or skeletons.
