Four data sets were analysed: a) the internal transcribed spacer region including ITS1, 5.8S rDNA and ITS2 (ITS), b) nc28S (ncLSU) rDNA, c) nc18S (ncSSU) rDNA, and d) a combined data set of ncLSU-ncSSU-RPB2 (ribosomal polymerase B2). The traditional placement of Ch. tulasneorum in the Microascales based on ncLSU sequences is unsupported and Australiasca does not belong to the Chaetosphaeriaceae. Both holomorph species are nested within the Glomerellales. A new genus, Reticulascus, is introduced for Ch. tulasneorum with associated Cylindrotrichum anamorph; another species of Reticulascus and its anamorph in Cylindrotrichum are described as new. The taxonomic structure of the Glomerellales is clarified and the name is validly published. As delimited here, it includes three families, the Glomerellaceae and the newly described Australiascaceae and Reticulascaceae. Based on ITS and ncLSU rDNA sequence analyses, we confirm the synonymy of the anamorph generaDischloridium with Monilochaetes. -

Kaan Kurtural * Department of Viticulture and Enology, University of California Davis, 1 Shields Avenue, Davis, CA 95616, USA; [email protected] (N.T.); [email protected] (R.Y.) * Correspondence: [email protected] † Current address: Advanced Fruit and Grape Growing Group, Public University of Navarra, 31006 Pamplona, Spain. Abstract: Vineyard-living microbiota affect grapevine health and adaptation to changing environ- ments and determine the biological quality of soils that strongly influence wine quality. However, their abundance and interactions may be affected by vineyard management. The present study was conducted to assess whether the vineyard soil microbiome was altered by the use of biostimulants (arbuscular mycorrhizal fungi (AMF) inoculation vs. non-inoculated) and/or irrigation management (fully irrigated vs. half irrigated). Bacterial and fungal communities in vineyard soils were shaped by both time course and soil management (i.e., the use of biostimulants and irrigation). Regarding alpha diversity, fungal communities were more responsive to treatments, whereas changes in beta diversity were mainly recorded in the bacterial communities. Edaphic factors rarely influence bacte- rial and fungal communities. Microbial network analyses suggested that the bacterial associations Citation: Torres, N.; Yu, R.; Kurtural, were weaker than the fungal ones under half irrigation and that the inoculation with AMF led to S.K. Inoculation with Mycorrhizal the increase in positive associations between vineyard-soil-living microbes. Altogether, the results Fungi and Irrigation Management highlight the need for more studies on the effect of management practices, especially the addition Shape the Bacterial and Fungal of AMF on cropping systems, to fully understand the factors that drive their variability, strengthen Communities and Networks in Vineyard Soils. -

Morphological re-examination of the strains was also carried out. Colletotrichum hsienjenchang on a bamboo, Phyllostachys bambusoides, collected in Kanagawa Prefecture, Japan in 2011 was found to produce tufted conidia on the top of polyphialides on PDA medium and large appressoria with a few short projections. Its strain was placed on a branch with C. spaethianum in an rDNA-ITS phylogram, but it was separat- ed on a branch near C. tofieldiae and other closely related species with falcate conidia in phylograms based on actin, chi- tin synthase 1 or histone 3 partial sequences. -

Characterising plant pathogen communities and their environmental drivers at a national scale A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University by Andreas Makiola Lincoln University, New Zealand 2019 General abstract Plant pathogens play a critical role for global food security, conservation of natural ecosystems and future resilience and sustainability of ecosystem services in general. Thus, it is crucial to understand the large-scale processes that shape plant pathogen communities. The recent drop in DNA sequencing costs offers, for the first time, the opportunity to study multiple plant pathogens simultaneously in their naturally occurring environment effectively at large scale. In this thesis, my aims were (1) to employ next-generation sequencing (NGS) based metabarcoding for the detection and identification of plant pathogens at the ecosystem scale in New Zealand, (2) to characterise plant pathogen communities, and (3) to determine the environmental drivers of these communities. First, I investigated the suitability of NGS for the detection, identification and quantification of plant pathogens using rust fungi as a model system. -

The taxonomic placement of the genus is discussed, and the evolution of our approach to species concepts and anamorph-teleomorph relationships is described. The application of multilocus technologies to phylogenetic analysis of Colletotrichum is reviewed, and selection of potential genes/loci for barcoding purposes is discussed. Host specificity and its relation to speciation and taxonomy is briefly addressed. A short review is presented of the current status of classification of the species clusters that are currently without comprehensive multilocus analyses, emphasising the orbiculare and destructivum aggregates. The future for Colletotrichum biology will be reliant on consensus classification and robust identification tools. In support of these goals, a Subcommission onColletotrichum has been formed under the auspices of the International Commission on Taxonomy of Fungi, which will administer a carefully curated barcode database for sequence-based identification of species within the BioloMICS web environment. Key words: anamorph-teleomorph linkages, barcoding, Colletotrichum, database, Glomerella, host specialisation, phylogeny, systematics, species concepts.

The Genera Colletotrichum: an Incitant of Numerous New Plant Diseases In
Journal on New Biological Reports 3(1): 09 – 21 (2014) ISSN 2319 – 1104 (Online) The genera Colletotrichum : an incitant of numerous new plant diseases in India Ajay Kumar Gautam Department of Botany, Abhilashi Institute of Life Sciences Mandi (HP) - 175008, India (Received on: 24 December, 2013; accepted on: 27 Feburary, 2014) ABSTRACT Colletotrichum is one of the most common and unusual plant pathogenic fungal genera causing variety of diseases. The genus is primerily responsible for an significant disease; anthracnose inhabiting a wide range of host’s worldwide. The objective of this paper is to review various diseases caused by Colletotrichum in India with special reference to plant diseases reported in present century (i.e. 2000-2012). About 25 plant diseases caused by different species of Colletotrichum namely, C. gloeosporioides , C. capsici , C. falcatum , C. truncatum , C. sansevieriae , C. acutatum and C. coccodes were reported in present century, in which C. gloeosporioides found more prevalent antracnose pathogen. The study showed that even a single species of Colletotrichum can affect multiple hosts. Therefore, the present compilation in my openion will not only provide useful information about new plant diseases caused by Colletotrichum , but also be helful for mycologists and plant pathologists in phytopathological research and will initiate new questions for future study. Key Words: Colletotrichum , new plant diseases, 21st century, India. INTRODUCTION Fungi include number of plant pathogens of major The genus is cosmopolitan in distribution and importance, causing diseases on wide variety of primary inoculum is disseminated by wind or rain, woody and herbaceous plants and Colletotrichum is virtually every crop grown throughout the world is one of the most common and unusual plant susceptible to one or more species of Colletotrichum . -

They contain information for use during the risk/safety assessment of transgenic organisms to be released in the of Transgenic Organisms environment, for agriculture, forestry or other purposes. The rst chapter deals with the low-level presence of transgenic plants in seed and grain commodities and how this knowledge can be used in biosafety regulatory in the Environment, Volume 6 assessment. The following chapters cover the biology of several crop species (sugarcane, cassava, common bean and cowpea) and include elements of taxonomy, centres of origin, reproductive biology, genetics, hybridisation and introgression, crop production and cultivation practices, interactions with other organisms OECD CONSENSUS DOCUMENTS such as pests and pathogens, and biotechnological developments. The last chapter relates to the biology of eucalyptus tree, focused on those species and hybrids which are planted commercially and might be the subject of genetic modi cation.
