Botryosphaeriaceae associated with Acacia heterophylla (La Réunion) and Acacia koa (Hawaii)
In this study, we compared the fungi in the Botryosphaeriaceae isolated from natural populations of A. koa and A. heterophylla. These fungi were chosen because they commonly occur on woody plants and some are important pathogens. They are also known to have been moved globally on asymptomatic plant materials. Isolates were identified based on comparisons of DNA sequence data for the rDNA-ITS, TEF1-α and β-tubulin loci. Ten Botryosphaeriaceae species were identified, of which four species were specific to A. koa from the Hawaiian Islands and five to A. heterophylla in La Réunion. Only one species, Neofusicoccum parvum...

A look into the genetic diversity of Lecanosticta acicola in northern Europe
This study gives a first look into the population genetics of the pathogen in Estonia, the first population documented in that region. The main aim of this study was to investigate the genetic diversity and population structure of the pathogen in this new region for the fungus. For this purpose, 104 isolates from 2010-2017 were analysed with 11 microsatellite and mating type markers. The stand where the pathogen´s jump from an exotic host to the native Scots pine was recorded was also involved in this analysis. The analysis revealed low genetic diversity and a high number of clones that indicated L. acicola is an invasive...

The role of in vitro cultivation on symbiotic trait and function variation in a single species of arbuscular mycorrhizal fungus
Publication date: Available online 28 June 2019Source: Fungal BiologyAuthor(s): Vasilis Kokkoris, Miranda M. HartAbstractIn vitro propagation of AM fungi using transformed root cultures (TRC) is commonly used to obtain pure AM fungal propagules for use in research and industry. Early observations indicate that such an artificial environment can alter traits and function of AM fungi over time. We hypothesized that increased in vitro cultivation may promote ruderal strategies in fungi by enhancing propagule production and reducing mutualistic quality. To examine the effect of in vitro cultivation on the trait and function ...

Cyclopiazonic acid gene expression as strategy to minimizing mycotoxin contamination in cheese
The objective of this study was to evaluate the influence of pH, aw, and temperature on expression of dmaT, which encodes the enzyme dimethylallyl tryptophan synthase involved in the biosynthesis of CPA. We assayed three Penicillium strains, P. commune CBS311 and CBS341 and P. camemberti CBS273, using reverse transcription real-time PCR. Our results showed that the expression patterns of the gene were influenced by strain and environmental conditions. The highest expression for the P. commune strains was observed at pH 6.0, 0.95 aw, at 25 or 30 ºC, depending on the strain. In contrast, P. camemberti CBS273 showed a lower ...

Trichoderma/pathogen/plant interaction in pre-harvest food security
Publication date: Available online 29 June 2019Source: Fungal BiologyAuthor(s): Roberto N. Silva, Valdirene Neves Monteiro, Andrei Stecca Steindorf, Eriston Viera Gomes, Eliane Ferreira Noronha, Cirano J. UlhoaAbstractLarge losses before crop harvesting are caused by plant pathogens, such as viruses, bacteria, oomycetes, fungi, and nematodes. Among these, fungi are the major cause of losses in agriculture worldwide. Plant pathogens are still controlled through application of agrochemicals, causing human disease and impacting environmental and food security. Biological control provides a safe alternative for the control of ...

The Talaromyces pinophilus species complex
Publication date: Available online 26 June 2019Source: Fungal BiologyAuthor(s): Stephen W. Peterson, Željko JurjevićAbstractA sample of isolates from T. pinophilus (55 isolates) and closely related species (76 isolates) was sequenced at four loci, the data were analyzed using maximum likelihood analysis and the GCPSR. The isolates were subjected to growth studies on the recommended media for description of Talaromyces species. On the basis of the combined data, five new species were segregated out of T. pinophilus and placed in newly described species. The Talaromyces pinophilus species complex contains ten species. The ...

Sexual reproduction of Zymoseptoria tritici on durum wheat in Tunisia revealed by presence of airborne inoculum, fruiting bodies and high levels of genetic diversity
The objective of the present study was to quantify the occurrence of Z. tritici sexual reproduction on durum wheat in the Tunisian environment. The assessment was undertaken using a triple approach combining fruiting body assessment, ascospore trapping and population genetic analyses. The results highlighted the formation of pseudothecia on leaves and stubble from the autumn until the end of the growing season. Likewise, qPCR monitoring highlighted a constant release of Z. tritici airborne inoculum during the wheat-growing season, with a peak of production at the end of the season. Genetic investigations using microsatelli...

Genome editing of different strains of Aureobasidium melanogenum using an efficient Cre/loxp site-specific recombination system
In this study, an efficient Cre/loxp site-specific recombination system (pAMGDloxp-1, pAMEXlox-1 and pAMCRE1) was constructed. It was found that they could be successfully used to sequentially delete and express many genes in different strains of A. melanogenum. After each round of gene disruption and expression, over 0.5 positive cells per 1000 competent cells and over 49.8 positive transformants per 1.0 μg DNA were achieved. After each round of the antibiotics gene excision by using the Cre-loxp site-specific recombination, over 95.4 % of the antibiotics-resistant cells became sensitive to both hygromycin B and nours...

Assortative mating in sympatric ascomycete fungi revealed by experimental fertilizations
Publication date: Available online 15 June 2019Source: Fungal BiologyAuthor(s): Artemis D. Treindl, Adrian LeuchtmannAbstractMate recognition mechanisms resulting in assortative mating constitute an effective reproductive barrier that may promote sexual isolation and speciation. While such mechanisms are widely documented for animals and plants, they remain poorly studied in fungi. As an experimental system, we used two interfertile species of the Epichloë typhina complex (Clavicipitaceae, Ascomycota), which are host-specific endophytes of sympatrically occurring grasses, Dactylis glomerata (infected by E. typhina) and Ho...
