Basidiomycete fungi are characterized ecologically for their vital functional role in ecosystem carbon recycling and chemically for their capacity to produce a diverse array of small molecules. Chromophoric natural products derived from the quinone precursor atromentin, such as variegatic acid and involutin, have been shown to function in redox cycling. Yet, in the context of an inter-kingdom natural system these pigments are still elusive. Here, we co-cultured the model saprotrophic basidiomycete Serpula lacrymans with an ubiquitous terrestrial bacterium, either Bacillus subtilis, Pseudomonas putida, or Streptomyces iranensis...

Among the invaluable benefits of basidiomycete genomics is the dramatically enhanced insight into the potential capacity to biosynthesize natural products. This study focuses on adenylate-forming reductases, which is a group of natural product biosynthesis enzymes that resembles non-ribosomal peptide synthetases, yet serves to modify one substrate, rather than to condense two or more building blocks. Phylogenetically, these reductases fall in four classes. The phylogeny of Heterobasidion annosum (Russulales) and Serpula lacrymans (Boletales) adenylate-forming reductases was investigated...

This work describes autofluorescence of the mycelium of the dry rot fungus Serpula lacrymans grown on spruce wood blocks impregnated with various metals. Live mycelium, as opposed to dead mycelium, exhibited yellow autofluorescence upon blue excitation, blue fluorescence with ultraviolet (UV) excitation, orange-red and light-blue fluorescence with violet excitation, and red fluorescence with green excitation. Distinctive autofluorescence was observed in the fungal cell wall and in granula localized in the cytoplasm...

In this study the genetic variation and population structure in a French population of the dry rot fungus S. lacrymans was investigated using 14 microsatellites markers and compared to the rest of Europe. In that comparison the French population possessed the same allelic diversity as rest of Europe. A weak geographic structuring of the genetic variation was observed across Europe, where the French isolates to some extent separated from the rest of Europe, indicating that weak barriers to gene flow exists. Eighty percent of the isolates had unique multilocus microsatellite genotypes, which corresponds to high recombination and dispersal by sexual spores...

In this study the genetic variation and population structure in a French population of the dry rot fungus Serpula lacrymans was investigated using fourteen microsatellites markers, and compared to the rest of Europe. The French population possessed the same allelic diversity as rest of Europe. A weak geographic structuring of the genetic variation was observed across Europe, where the French isolates to some extent separated from the rest of Europe, indicating that weak barriers to gene flow exists. 80% of the isolates had unique multi-locus microsatellite genotypes, which is in correspondence with high levels of recombination and dispersal by sexual spores...

This study analyzes the accumulation and translocation of metal ions in wood during the degradation performed by one strain of each of the three brown rot fungi; Serpula lacrymans, Meruliporia incrassata and Coniophora puteana. These fungi species are inhabitants of the built environment where the prevention and understanding of fungal decay is of high priority. This study focuses on the influence of various building materials in relation to fungal growth and metal uptake. Changes in the concentration of iron, manganese, calcium and copper ions in the decayed wood were analyzed by induced coupled plasma spectroscopy and related to wood weight loss and oxalic acid accumulation...

Genome sequencing of basidiomycetes, a group of fungi capable of degrading/mineralizing plant material, revealed the presence of numerous cytochrome P450 monooxygenases (P450s) in their genomes, with some exceptions. Considering the large repertoire of P450s found in fungi, it is difficult to identify P450s that play an important role in fungal metabolism and the adaptation of fungi to diverse ecological niches. In this study, we followed Sir Charles Darwin's theory of natural selection to identify such P450s in model basidiomycete fungi showing a preference for different types of plant components degradation...

Different mating systems have evolved in the fungal kingdom, including a tetrapolar multiallelic mating system in many basidiomycetes. In tetrapolar species, the presence of different alleles at two mating loci (MAT A and MAT B) is necessary for mating to occur. The tetrapolar fungus Serpula lacrymans causes wood-decay in buildings in temperate regions worldwide and is present in Europe with a genetically homogeneous founder population. Using genome sequence data, we annotated the two mating type loci for S...

Basidiomycetes that cause brown rot of wood are essential biomass recyclers in coniferous forest ecosystems and a major cause of failure in wooden structures. Recent work indicates that distinct lineages of brown rot fungi have arisen independently from ligninolytic white rot ancestors via loss of lignocellulolytic enzymes. Brown rot thus proceeds without significant lignin removal, apparently beginning instead with oxidative attack on wood polymers by Fenton reagent produced when fungal hydroquinones or catechols reduce Fe(3+) in colonized wood...

Simple sequence repeats (SSRs) or microsatellites are one of the most popular sources of genetic markers and play a significant role in gene function and genome organization. We identified SSRs in the genome of Ganoderma lucidum and analyzed their frequency and distribution in different genomic regions. We also compared the SSRs in G. lucidum with six other Agaricomycetes genomes: Coprinopsis cinerea, Laccaria bicolor, Phanerochaete chrysosporium, Postia placenta, Schizophyllum commune and Serpula lacrymans...

S C Watkinson, D C Eastwood
Serpula lacrymans, the causative agent of dry rot timber decay in buildings, is a Basidiomycete fungus in the Boletales clade. It owes its destructiveness to a uniquely well-developed capacity to colonize by rapid mycelial spread from sites of initial spore infection, coupled with aggressive degradation of wood cellulose. Genomic methods have recently elucidated the evolution and enzymic repertoire of the fungus, suggesting that it has a distinctive mode of brown rot wood decay. Using novel methods to image nutrient translocation, its mycelium has been modeled as a highly responsive resource-supply network...

The feasibility of short-read sequencing for genomic analysis was demonstrated for Fibroporia radiculosa, a copper-tolerant fungus that causes brown rot decay of wood. The effect of read quality on genomic assembly was assessed by filtering Illumina GAIIx reads from a single run of a paired-end library (75-nucleotide read length and 300-bp fragment size) at three different stringency levels and then assembling each data set with Velvet. A simple approach was devised to determine which filter stringency was "best...

AIMS: To predict the risk factors for building infestation by Serpula lacrymans, which is one of the most destructive fungi causing timber decay in buildings. METHODS AND RESULTS: The growth rate was assessed on malt extract agar media at temperatures between 1.5 and 45°C, at water activity (a(w)) over the range of 0.800-0.993 and at pH ranges from 1.5 to 11.0. The radial growth rate (μ) and the lag phase (λ) were estimated from the radial growth kinetics via the plots radius vs time...

BACKGROUND: The fungal genus Serpula (Serpulaceae, Boletales) comprises several saprotrophic (brown rot) taxa, including the aggressive house-infecting dry rot fungus Serpula lacrymans. Recent phylogenetic analyses have indicated that the ectomycorrhiza forming genera Austropaxillus and Gymnopaxillus cluster within Serpula. In this study we use DNA sequence data to investigate phylogenetic relationships, historical biogeography of, and nutritional mode transitions in Serpulaceae. RESULTS: Our results corroborate that the two ectomycorrhiza-forming genera, Austropaxillus and Gymnopaxillus, form a monophyletic group nested within the saprotrophic genus Serpula, and that the Serpula species S...

Brown rot decay removes cellulose and hemicellulose from wood--residual lignin contributing up to 30% of forest soil carbon--and is derived from an ancestral white rot saprotrophy in which both lignin and cellulose are decomposed. Comparative and functional genomics of the "dry rot" fungus Serpula lacrymans, derived from forest ancestors, demonstrated that the evolution of both ectomycorrhizal biotrophy and brown rot saprotrophy were accompanied by reductions and losses in specific protein families, suggesting adaptation to an intercellular interaction with plant tissue...

Jonathan S Schilling, K Brook Jacobson
The two principal methods for studying fungal biodegradation of lignocellulosic plant tissues were developed for wood preservative testing (soil-block; agar-block). It is well-accepted that soil-block microcosms yield higher decay rates, fewer moisture issues, lower variability among studies, and higher thresholds of preservative toxicity. Soil-block testing is thus the more utilized technique and has been standardized by American Society for Testing and Materials (ASTM) (method D 1413-07). The soil-block design has drawbacks, however, using locally-variable soil sources and in limiting the control of nutrients external (exogenous) to the decaying tissues...

Serpula lacrymans is the most notorious decayer of wooden buildings in temperate regions. The occurrence of geographically widespread vegetative compatibility groups (VCG) in S. lacrymans in Europe is demonstrated in this study. Among 22 heterokaryotic isolates of S. lacrymans, five VCG were found. The most widespread VCG included isolates from Belgium, south and central Norway, separated by more than 1500 km. No other genetic variation, measured as DNA sequence variation or ISSR polymorphisms, was detected between the investigated S...

Early detection of indoor wood-decay fungi is crucial to prevent building deterioration and thereby avoid considerable economic loss. Due to their increased sensitivity, two reliable DNA-based fingerprinting techniques, capillary electrophoresis single-strand conformation polymorphism (CE-SSCP) and denaturing high-performance liquid chromatography (DHPLC), were used to identify Serpula lacrymans and to profile wood-rot Basidiomycetes in the built environment. Molecular fungal diversity was assessed on 74 environmental samples, collected from 2003 to 2009 from infected buildings in France...

BACKGROUND: The mating type loci that govern the mating process in fungi are thought to be influenced by negative frequency-dependent selection due to rare allele advantage. In this study we used a mating type linked DNA marker as a proxy to indirectly study the allelic richness and geographic distribution of mating types of one mating type locus (MAT A) in worldwide populations of the dry rot fungus Serpula lacrymans. This fungus, which causes serious destruction to wooden constructions in temperate regions worldwide, has recently expanded its geographic range with a concomitant genetic bottleneck...

The dry rot fungus Serpula lacrymans is a devastating basidiomycete occurring in wooden constructions in temperate regions worldwide. In this study, we compare the genetic structures of two invasive populations from Europe and Japan. Microsatellite data from 14 loci and DNA sequences from four loci demonstrated that the two populations were highly differentiated. Significant isolation by distance effect was observed in Europe and Japan. Higher genetic variation was observed within the Japanese population than within the European population, corresponding with the observed higher richness of vegetative compatibility types in Japan, indicating that there has been a higher level of gene flow from the Asian source populations to Japan than to Europe...
