Controlled release of biocides in solid wood. I. Efficacy against brown rot wood decay fungus (Gloeophyllum trabeum)

ABSTRACT The brown-rot basidiomycete Gloeophyllum trabeum uses a quinone redox cycle to generate extracellular Fenton reagent, a key component of the biodegradative system expressed by this highly destructive wood decay fungus. The hitherto uncharacterized quinone reductase that drives this cycle is a potential target for inhibitors of wood decay. We have identified the major quinone reductase expressed by G. trabeum under conditions that elicit high levels of quinone redox cycling. The enzyme comprises two identical 22-kDa subunits, each with one molecule of flavin mononucleotide. It is specific for NADH as the reductant and uses the quinones produced by G. trabeum (2,5-dimethoxy-1,4-benzoquinone and 4,5-dimethoxy-1,2-benzoquinone) as electron acceptors. The affinity of the reductase for these quinones is so high that precise kinetic parameters were not obtainable, but it is clear that k cat/Km for the quinones is greater than 108 M−1 s−1. The reductase is encoded by a gene with substantial similarity to NAD(P)H:quinone reductase genes from other fungi. The G. trabeum quinone reductase may function in quinone detoxification, a role often proposed for these enzymes, but we hypothesize that the fungus has recruited it to drive extracellular oxyradical production.

Abstract This paper provides a list of intracellular isozyme systems of Trichaptum abietinum (J. Dicks.) Ryvarden (Basidiomycetes) that can be used for population studies. Population structure of the fungus within the Carpathian National Nature Park (CNNP) was established. Percent of polymorphic loci in general was 83.3%. Groups of rare alleles were assigned Sod88, Sod138, Sdh191, and Est111. Calculated Wright's fixation index allowed establishing privilege of the heterozygotes on locus Acp and homozygotes on locus Sod. The population of T. abietinum in the CNNP was in equilibrium state.
