(Hypocreaceae) has the smallest mitogenome of the genus .

Introduction: Fungal mitogenomes exhibit remarkable variation in conformation, size, gene content, arrangement and expression, including their intergenic spacers and introns.

Methods: The complete mitochondrial genome sequence of the mycoparasitic fungus was determined using the Illumina next-generation sequencing technology. We used data from our recent Illumina NGS-based project of genome sequencing to study its mitochondrial genome.

Are dark septate endophytes an ancestral ecological state in the evolutionary history of the order Chaetothyriales?

Dark septate endophytes (DSE) are pigmented fungi that colonize plant roots. They represent a morpho-functional status composed of many species belonging to the phylum Ascomycota, distributed in different orders. The order Chaetothyriales has representatives with diverse lifestyles, among which the rock-inhabiting one has been proposed to be the ancestral ecological character state.

Fungal Mitogenomes: Relevant Features to Planning Plant Disease Management.

Mitochondrial genomes (mt-genomes) are characterized by a distinct codon usage and their autonomous replication. Mt-genomes encode highly conserved genes (mt-genes), like proteins involved in electron transport and oxidative phosphorylation but they also carry highly variable regions that are in part responsible for their high plasticity. The degree of conservation of their genes is such that they allow the establishment of phylogenetic relationships even across distantly related species.

Assemblage of dematiaceous and Ingoldian fungi associated with leaf litter of decomposing Typha latifolia L. (Typhaceae) in riverine wetlands of the Pampean plain (Argentina) exposed to different water quality.

The purpose of this study was to analyze the rate of sporulation, richness, and spore diversity of dematiaceous and Ingoldian fungi colonizing Typha latifolia leaves during a 40-day period of decomposition, as well as the loss of mass in Typha latifolia, in four riverine wetlands of Pampean plain (Argentina) with different water quality. Higher sporulation rates, richness, and diversity of the fungi as well as loss of mass of the leaves that they colonized were associated with lower water quality. Anguilospora longissima, Arthrinium sp.

Draft Genome Sequences of Sporulating (CIDEFI-213) and Nonsporulating (CIDEFI-212) Strains of Stemphylium lycopersici.

Stemphylium lycopersici (Pleosporales) is a pathogenic fungus found on a broad range of plant hosts. It is one of the causal agents of gray leaf spot disease in tomato that causes severe yield reductions and economic losses worldwide. Here, we present the draft genome sequences and the gene annotations of two strains of S.

Enhancing laccase production by white-rot fungus Funalia floccosa LPSC 232 in co-culture with Penicillium commune GHAIE86.

To obtain enzymatic preparations with higher laccase activity levels from Funalia floccosa LPSC 232, available for use in several applications, co-cultures with six filamentous microfungi were tested. A laccase non-producing soil fungus, identified as Penicillium commune GHAIE86, showed an outstanding ability to increase laccase activity (3-fold as compared to that for monoculture) when inoculated in 6-day-old F. floccosa cultures.

The mitochondrial genome of the plant-pathogenic fungus Stemphylium lycopersici uncovers a dynamic structure due to repetitive and mobile elements.

Stemphylium lycopersici (Pleosporales) is a plant-pathogenic fungus that has been associated with a broad range of plant-hosts worldwide. It is one of the causative agents of gray leaf spot disease in tomato and pepper. The aim of this work was to characterize the mitochondrial genome of S.

The Use of Gamma Radiation for the Treatment of Cultural Heritage in the Argentine National Atomic Energy Commission: Past, Present, and Future.

The use of gamma radiation for treating biodeteriorated cultural heritage on paper has been studied at the Comisión Nacional de Energía Atómica-CNEA (Argentina) since 2001. In order to preserve books, publications, and documents that have been attacked by insects or fungi, gamma radiation techniques have been used at CNEA. The activities include basic research as well as their applications in infected documents and papers currently used in libraries and archives.

α-L-rhamnosidase and β-D-glucosidase activities in fungal strains isolated from alkaline soils and their potential in naringin hydrolysis.

α-L-Rhamnosidases (EC 3.2.1.

Decolorization of synthetic dyes by the deuteromycete Pestalotiopsis guepinii CLPS no. 786 strain.

The ability of Pestalotiopsis guepinii CLPS no. 786 to decolorize 13 dyes of varied structure was analyzed and compared with that of the basidiomycete Phanerochaete chrysosporium . Nine dyes representing anthrapyridone, azo, N-heterocyclic and triphenylmethane chromophores, but none with the O-heterocyclic group, were decolorized by P.

Screening for ligninolytic enzymes in autochthonous fungal strains from Argentina isolated from different substrata.

The production of different extracellular ligninolytic enzymes was studied in autochthonous fungal strains from Argentina isolated from litter derived from hydrocarbon-polluted sites and from basidiocarps frowing on wood in forests. The strains tested were cultivated in a carbon-limited medium with shaking. Laccase activity reached higher levels than aryl-alcohol oxidase and manganese-dependent peroxidase activities in liquid cultures from different fungi.
