Pheromone receptor Consistent with a role of mating type in mediating cytoplasmic-nuclear genomic conflict, Agaricomycetes have evolved away from a haploid yeast phase towards hyphal fusions that display reciprocal nuclear migration after mating rather than cytoplasmic fusion. Importantly, the evolution of this mating behavior is precisely timed with the onset of diversification of mating type alleles at the pheromone/receptor mating type loci that are known to control reciprocal nuclear migration during mating. -

During a study of the fungal diversity of 12 undiscovered taxa in Korea, two mucoralean strains, CNUFC-GWD3-9 and CNUFC-EGF1-4, were 13 isolated from specific habitats including freshwater and fecal samples, respectively, in Korea. The 14 strains were analyzed both for morphology and phylogeny based on the internal transcribed 15 spacer (ITS) and large subunit (LSU) of 28S ribosomal DNA regions. On the basis of their 16 morphological characteristics and sequence analyses, isolates CNUFC-GWD3-9 and CNUFC- 17 EGF1-4 were confirmed to be Gilbertella persicaria and Pilobolus crystallinus, respectively.To the 18 best of our knowledge, there are no published literature records of these two genera in Korea. 19 Keywords: Gilbertella persicaria; Pilobolus crystallinus; mucoralean fungi; phylogeny; morphology; 20 undiscovered taxa 21 22 1.

Fungal Evolution: Major Ecological Adaptations and Evolutionary Transitions
Biol. Rev. (2019), pp. 000–000. 1 doi: 10.1111/brv.12510 Fungal evolution: major ecological adaptations and evolutionary transitions Miguel A. Naranjo-Ortiz1 and Toni Gabaldon´ 1,2,3∗ 1Department of Genomics and Bioinformatics, Centre for Genomic Regulation (CRG), The Barcelona Institute of Science and Technology, Dr. Aiguader 88, Barcelona 08003, Spain 2 Department of Experimental and Health Sciences, Universitat Pompeu Fabra (UPF), 08003 Barcelona, Spain 3ICREA, Pg. Lluís Companys 23, 08010 Barcelona, Spain ABSTRACT Fungi are a highly diverse group of heterotrophic eukaryotes characterized by the absence of phagotrophy and the presence of a chitinous cell wall. While unicellular fungi are far from rare, part of the evolutionary success of the group resides in their ability to grow indefinitely as a cylindrical multinucleated cell (hypha). Armed with these morphological traits and with an extremely high metabolical diversity, fungi have conquered numerous ecological niches and have shaped a whole world of interactions with other living organisms. Herein we survey the main evolutionary and ecological processes that have guided fungal diversity. We will first review the ecology and evolution of the zoosporic lineages and the process of terrestrialization, as one of the major evolutionary transitions in this kingdom. Several plausible scenarios have been proposed for fungal terrestralization and we here propose a new scenario, which considers icy environments as a transitory niche between water and emerged land. We then focus on exploring the main ecological relationships of Fungi with other organisms (other fungi, protozoans, animals and plants), as well as the origin of adaptations to certain specialized ecological niches within the group (lichens, black fungi and yeasts). -

Tretter1, E.M. Johnson1, Y. Wang1, P. Kandel1, M.M. White1 Key words Abstract The recently recognised protein-coding genes MCM7 and TSR1 have shown significant promise for phylo genetic resolution within the Ascomycota and Basidiomycota, but have remained unexamined within other DNA replication licensing factor fungal groups (except for Mucorales). We designed and tested primers to amplify these genes across early-diverging Harpellales fungal clades, with emphasis on the Kickxellomycotina, zygomycetous fungi with characteristic flared septal walls Kickxellomycotina forming pores with lenticular plugs. Phylogenetic tree resolution and congruence with MCM7 and TSR1 were com- MCM7 pared against those inferred with nuclear small (SSU) and large subunit (LSU) rRNA genes. We also combined MS277 MCM7 and TSR1 data with the rDNA data to create 3- and 4-gene trees of the Kickxellomycotina that help to resolve MS456 evolutionary relationships among and within the core clades of this subphylum. Phylogenetic inference suggests ribosomal biogenesis protein that Barbatospora, Orphella, Ramicandelaber and Spiromyces may represent unique lineages. It is suggested that Trichomycetes these markers may be more broadly useful for phylogenetic studies among other groups of early-diverging fungi.

A Silver Bullet in a Golden Age of Functional Genomics: the Impact of Agrobacterium-Mediated Transformation of Fungi
Idnurm et al. Fungal Biol Biotechnol (2017) 4:6 DOI 10.1186/s40694-017-0035-0 Fungal Biology and Biotechnology REVIEW Open Access A silver bullet in a golden age of functional genomics: the impact of Agrobacterium‑mediated transformation of fungi Alexander Idnurm1* , Andy M. Bailey2, Timothy C. Cairns3, Candace E. Elliott1, Gary D. Foster2, Giuseppe Ianiri4 and Junhyun Jeon5 Abstract The implementation of Agrobacterium tumefaciens as a transformation tool revolutionized approaches to discover and understand gene functions in a large number of fungal species. A. tumefaciens mediated transformation (AtMT) is one of the most transformative technologies for research on fungi developed in the last 20 years, a development arguably only surpassed by the impact of genomics. AtMT has been widely applied in forward genetics, whereby generation of strain libraries using random T-DNA insertional mutagenesis, combined with phenotypic screening, has enabled the genetic basis of many processes to be elucidated. Alternatively, AtMT has been fundamental for reverse genet- ics, where mutant isolates are generated with targeted gene deletions or disruptions, enabling gene functional roles to be determined. When combined with concomitant advances in genomics, both forward and reverse approaches using AtMT have enabled complex fungal phenotypes to be dissected at the molecular and genetic level. Addition- ally, in several cases AtMT has paved the way for the development of new species to act as models for specifc areas of fungal biology, particularly in plant pathogenic ascomycetes and in a number of basidiomycete species. Despite its impact, the implementation of AtMT has been uneven in the fungi. This review provides insight into the dynamics of expansion of new research tools into a large research community and across multiple organisms. -

Reference Guide to the Classification of Fungi and Fungal-Like Protists, with Emphasis on the Fungal Genera with Medical Importance (Circa 2009)
Reference Guide to the Classification of Fungi and Fungal-like Protists, with Emphasis on the Fungal Genera with Medical Importance (circa 2009) This outline lists some common genera of fungi and fungal-like protists, which are classified into a number of phyla, subphyla, classes, subclasses and in most cases orders and families. The classification is patterned after the broad schemes of Hawksworth et al. (1), Kirk et al. (2), Eriksson et al. (3), Alexopoulos et al. (4), and Blackwell et al (5) and was devised by PJS to reflect his perception of the relationships of the various organisms traditionally studied by mycologists and included in textbooks and manuals dealing with mycology. The classification ranks below class reflect interpretations of Alexopoulos et al. (7), and PJS. It should be noted that different biologists until recently have had varying opinions on which organisms to include in the Kingdom Fungi and on what rank should be accorded each major group. This classification outline distributes the fungi and fungal-like organisms often dealt with in traditional mycology among the three kingdoms, Protozoa, Chromista and Fungi. With only a relatively few exceptions, the genera listed are very common or are of medical importance. However, not all genera of the Kingdom Fungi involved in human and animal medical mycology are listed. Kingdom: Protozoa/Amebozoa/Eumycetozoa (collection of numerous phyla of eukaryotic, generally wall- less, unicellular, plasmodial, or colonial phagotrophic microorganisms, which includes at least four fungal-like phyla that are no longer considered to be part of the Kingdom Fungi). These have all been reclassified and renamed to reflect their nonfungal nature (see for example Reading Sz 5, which discusses the reclassification of Rhinosporidium seeberi into the additional new Phylum Mezomycetozoea). -
