Osmotolerance as a determinant of microbial ecology: A study of phylogenetically diverse fungi
Publication date: Available online 16 September 2019Source: Fungal BiologyAuthor(s): Claudinéia A.S. Araújo, Paulo C. Ferreira, Breno Pupin, Luciana P. Dias, Javier Avalos, Jessica Edwards, John E. Hallsworth, Drauzio E.N. RangelAbstractOsmotic stress induced by high solute concentration can prevent fungal metabolism and growth due to alterations in properties of the cytosol, changes in turgor, and the energy required to synthesize and retain compatible solutes. We used germination to quantify tolerance/sensitivity to the osmolyte KCl (0.1 to 4.5 M, in 0.1 M increments) for 70 strains (40 species) of ecologically diverse...

Can discrepancies between Fusarium graminearum trichothecene genotype and chemotype be explained by the influence of temperature in the relative production of 3-ADON and 15-ADON?
Publication date: Available online 13 September 2019Source: Fungal BiologyAuthor(s): Diana Ramírez Albuquerque, Andrea Patriarca, Virginia Fernández PintoAbstractWheat is one of the most important crops in Argentina and worldwide. One of the major diseases affecting the crop is the Fusarium Head Blight (FHB). It is an endemic disease caused mainly by Fusarium graminearum, the most common agent of FHB around the world. The infection is strongly influenced by environmental parameters and occurs mostly when there are favourable conditions of moisture and temperature during wheat anthesis or flowering. This destructive disea...

Telomeres and stress in yeast cells: when genes and environment interact
Publication date: Available online 13 September 2019Source: Fungal BiologyAuthor(s): Yaniv Harari, Lihi Gershon, Elisa Alonso-Perez, Shir Klein, Yael Berneman, Karan Choudhari, Pragyan Singh, Soumitra Sau, Batia Liefshitz, Martin KupiecAbstractTelomeres are structures composed of simple DNA repeats and specific proteins that protect the eukaryotic chromosomal ends from degradation, and facilitate the replication of the genome. They are central to the maintenance of the genome integrity, and play important roles in the development of cancer and in the process of aging in humans. The yeast Saccharomyces cerevisiae has greatl...

A newly constructed Agrobacterium-mediated transformation system revealed the influence of nitrogen sources on the function of the LaeA regulator in Penicillium chrysogenum
In this study, we have constructed a new and efficient Agrobacterium tumefaciens-mediated transformation (ATMT) system with two different selection markers conferring the resistance to nourseothricin and phleomycin for P. chrysogenum. Under the optimized conditions for co-cultivation at 22°C for 60 h with acetosyringone concentration of 200 μM, the transformation efficiency of the ATMT system could reach 5009 ± 96 transformants per 106 spores. The obtained transformants could be exploited as the T-DNA insertion mutants for screening genes involved in morphogenesis and secondary metabolism. Especially, the constructed AT...

Unveiling annual growth chronologies from inter-nodal branch elongations in a fruticose lichen in southern Europe
Publication date: Available online 3 September 2019Source: Fungal BiologyAuthor(s): Alba E. Rodríguez-Peñate, Adrián Escudero, Isabel Martínez, Jaime Madrigal-GonzálezAbstractTechniques for retrospective analysis of size dynamics at annual resolution remain poorly developed in lichens in general, and fruticose lichens in particular. Only a few attempts in very high latitudes suggested that growth might be studied as a chronosequence of inter-nodal branch elongations. Here we evaluated, for the first time, this hypothesis in a dry Mediterranean environment using the lichen Cladonia rangiformis as a case study. Mixed mo...

Photodynamic inactivation of Candida albicans and Candida tropicalis with aluminum phthalocyanine chloride nanoemulsion
Publication date: Available online 23 August 2019Source: Fungal BiologyAuthor(s): Gabriela Braga Rodrigues, Guilherme T.P. Brancini, Marcelo Rodrigues Pinto, Fernando Lucas Primo, Mark Wainwright, Antonio Claudio Tedesco, Gilberto Úbida Leite BragaAbstractCandida albicans and Candida tropicalis are commensal yeasts able to cause human infections. The increased incidence of Candida spp. infections and fungal resistance to conventional antifungal drugs are recurring problems. Antimicrobial Photodynamic Treatment (APDT) is a promising alternative that uses a photosensitizer (PS), which when activated by light in the presence...

Evaluation of the rust fungus Puccinia rapipes for biological control of Lycium ferocissimum (African boxthorn) in Australia: life cycle, taxonomy and pathogenicity
Publication date: Available online 21 August 2019Source: Fungal BiologyAuthor(s): Kylie B. Ireland, Gavin C. Hunter, Alan Wood, Caroline Delaisse, Louise MorinAbstractFungal plant pathogens are increasingly recognised as being among the most effective and safe agents in classical weed biological control programs worldwide. Suitability of the rust fungus Puccinia rapipes as a classical biological control agent for Lycium ferocissimum (African boxthorn) in Australia was assessed using a streamlined agent selection framework. Studies with P. rapipes were undertaken to elucidate its life cycle, confirm its taxonomic placement ...

Ecophysiology of Penicillium expansum and patulin production in synthetic and olive-based media
Publication date: Available online 21 August 2019Source: Fungal BiologyAuthor(s): Mohamed Hamdi, Hend Bejaoui, Jorge Sá-Morais, Paula RodriguesAbstractOlives and their derivatives, in particular olive oil, represent one of the most significant agricultural products in the Mediterranean basin. Storage under inadequate conditions poses serious problems concerning fungal contamination, with consequent defects and potential mycotoxin production in olives and olive oils. Penicillium expansum represents one of the most significant postharvest pathogens in several fruits, including olives. Not only it causes blue mold but also i...

Mycotoxins Occurrence And Fungal Populations In Different Types Of Silages For Dairy Cows In Spain
In this study, samples of different kinds of silages (maize, grass, alfalfa, sugar beer pulp, immature corn and ryegrass) collected from farms located in four regions of Spain, were analysed to evaluate the occurrence of aflatoxins (AFs) and Fusarium mycotoxins. Their lactic acid bacteria and fungal populations as well as pH and water activity were also studied. Penicillium (4-26%), Geotrichum (2-21%) and Monascus (0.34-3%) were the main fungi identified in all the silages examined. Aspergillus was found in some maize, grass and alfalfa silage samples and Fusarium was only identified in 0.03% of grass silage samples. The i...

Publication date: Available online 14 August 2019Source: Fungal BiologyAuthor(s): Marta Tischer, Michał Gorczak, Błażej Bojarski, Julia Pawłowska, Christel Hoffeins, Hans Werner Hoffeins, Marta WrzosekAbstractThree new fossils of saprotrophic fungi are presented and described from Baltic amber, dated to Eocene epoch (Paleogene, upper to mid-Eocene). All belong to Ascomycota and are represented by hyphae as well as asexual reproduction structures allowing to assign them to present genera, respectively Periconia, Penicillium and Scopulariopsis. These material provide both the first and the oldest known fossil record of t...

Reassessment of Paragnomonia (Sydowiellaceae, Diaporthales) and typification of Paragnomonia fragariae, the cause of strawberry root rot and petiole blight
Publication date: Available online 15 August 2019Source: Fungal BiologyAuthor(s): Inga Moročko-Bičevska, Jamshid Fatehi, Olga SokolovaAbstractParagnomonia fragariae is a plant pathogenic ascomycete causing root rot and petiole blight of perennial strawberry in northern Europe. It was first described as Gnomonia fragariae in Germany by Klebahn in 1918. Since its discovery, the identity of this fungus has been the subject of confusion with the other strawberry pathogen Gnomoniopsis fructicola that causes fruit rot, leaf blotch and stem end rot. This paper provides a revised description of Paragnomonia and P. fragariae with...

Effect of depleted uranium on a soil microcosm fungal community and influence of a plant-ectomycorrhizal association
Publication date: Available online 12 August 2019Source: Fungal BiologyAuthor(s): Marina Fomina, Ji Won Hong, Geoffrey Michael GaddAbstractFungi are one of the most biogeochemically active components of the soil microbiome, becoming particularly important in metal polluted terrestrial environments. There is scant information on the mycobiota of uranium (U) polluted sites and the effect of metallic depleted uranium (DU) stress on fungal communities in soil has not been reported. The present study aimed to establish the effect of DU contamination on a fungal community in soil using a culture-independent approach, fungal ribo...
