101 Dothideomycetes genomes: a test case for predicting lifestyles and emergence of pathogens
Dothideomycetes is the largest class of kingdom Fungi and comprises an incredible diversity of lifestyles, many of which have evolved multiple times. Plant pathogens represent a major ecological niche of the class ... -
Basidiomycetes telomeres: a bioinformatics approach
The bioinformatics analysis described in this paper allowed us to establish the type and the number of the telomere repeat unit in the basidiomycetes analyzed, to suggest the putative linkage groups in fungi where linkage ... -
Characterization of transposon activity and genome-wide epigenetic regulation throughout the life cycle of Pleurotus ostreatus
Most prokaryotic and eukaryotic life forms have to deal with the presence of repetitive DNA sequences called transposable elements (TEs), whose ability to mobilize through the genome and insert at random position has an ... -
Comparative and transcriptional analysis of the predicted secretome in the lignocellulose-degrading basidiomycete fungus Pleurotus ostreatus
Fungi interact with their environment by secreting proteins to obtain nutrients, elicit responses and modify their surroundings. Because the set of proteins secreted by a fungus is related to its lifestyle, it should be ... -
Comparative genomics of Coniophora olivacea reveals different patterns of genome expansion in Boletales
Background: Coniophora olivacea is a basidiomycete fungus belonging to the order Boletales that produces brown-rot decay on dead wood of conifers. The Boletales order comprises a diverse group of species including saprotrophs ... -
Expresión génica de peroxidasas ligninolíticas en Pleurotus ostreatus: regulación por temperatura y pH
Pleurotus ostreatus es un hongo comestible de gran importancia biotecnológica por ser un organismo modelo degradador de lignina. Su genoma contiene nueve genes codificantes de peroxidasas ligninolíticas, características ... -
Genomic analysis enlightens agaricales lifestyle evolution and increasing peroxidase diversity
As actors of global carbon cycle, Agaricomycetes (Basidiomycota) have developed complex enzymatic machineries that allow them to decompose all plant polymers, including lignin. Among them, saprotrophic Agaricales are ... -
Genomics and transcriptomics characterization of genes expressed during postharvest at 4 degrees C by the edible basidiomycete Pleurotus ostreatus
Pleurotus ostreatus is an industrially cultivated basidiomycete with nutritional and environmental applications. Its genome, which was sequenced by the joint Genome Institute, has become a model for lignin degradation ... -
Highly expressed captured genes and cross-kingdom domains present in Helitrons create novel diversity in Pleurotus ostreatus and other fungi
Background: Helitrons are class-II eukaryotic transposons that transpose via a rolling circle mechanism. Due to their ability to capture and mobilize gene fragments, they play an important role in the evolution of their ... -
Ligninolytic peroxidase gene expression by Pleurotus ostreatus: differential regulation in lignocellulose medium and effect of temperature and pH
Pleurotus ostreatus is an important edible mushroom and a model lignin degrading organism, whose genome contains nine genes of ligninolytic peroxidases, characteristic of white-rot fungi. These genes encode six manganese ... -
Non-additive transcriptional profiles underlie dikaryotic superiority in Pleurotus ostreatus laccase activity
Background: The basidiomycete Pleurotus ostreatus is an efficient producer of laccases, a group of enzymes appreciated for their use in multiple industrial processes. The aim of this study was to reveal the molecular basis ... -
Somatic transposition and meiotically driven elimination of an active helitron family in Pleurotus ostreatus
Helitrons constitute a superfamily of DNA transposons that were discovered in silico and are widespread in most eukaryotic genomes. They are postulated to mobilize through a “rollingcircle” mechanism, but the experimental ... -
Transcriptional and enzymatic profiling of Pleurotus ostreatus laccase genes in submerged and solid-state fermentation cultures
The genome of the white rot basidiomycete Pleurotus ostreatus includes 12 phenol oxidase (laccase) genes. In this study, we examined their expression profiles in different fungal strains under different culture conditions ... -
Transposable elements in basidiomycete fungi: dynamics and impact on genome architecture and transcriptional profiles
Transposable elements (TE), also known as mobile elements or transposons, are enigmatic genetic units that have played important roles in the evolution of eukaryotes. Their impact on genome architecture and phenotypic ... -
Transposable elements versus the fungal genome: impact on whole-genome architecture and transcriptional profiles
Transposable elements (TEs) are exceptional contributors to eukaryotic genome diversity. Their ubiquitous presence impacts the genomes of nearly all species and mediates genome evolution by causing mutations and chromosomal ... -
Transposon-associated epigenetic silencing during Pleurotus ostreatus life cycle
Transposable elements constitute an important fraction of eukaryotic genomes. Given their mutagenic potential, host-genomes have evolved epigenetic defense mechanisms to limit their expansion. In fungi, epigenetic modifications ... -
Validation of reference genes for transcriptional analyses in Pleurotus ostreatus by using reverse transcription-quantitative PCR
Recently, the lignin-degrading basidiomycete Pleurotus ostreatus has become a widely used model organism for fungal genomic and transcriptomic analyses. The increasing interest in this species has led to an increasing ...
