DNA-hybridisation studies showed a close relationship between Phanerochaete chrysosporium ME446, most used in lignin degradation studies, and Sporotrichum pulverulentum Novobranova, the other standard lignin degrading strain. Two other strains of P. chrysosporium were both less related. We show that P. chrysosporium ME446 and S. pulverulentum Novobranova(More)
In this study, two transformation vectors (pMG101 and pMG103) for Phanerochaete chrysosporium were constructed, based on the ble phleomycin-resistance-encoding gene and a homologous histone H4 promoter. Transformation frequencies were 6-10 per micrograms of DNA. Transformed vector DNA could either exist as an unstable replicating plasmid or could be stably(More)
We have investigated four distinct sequences in genomic DNA of Phanerochaete chrysosporium that show strong homology to a lignin peroxidase cDNA sequence [Tien and Tu: Nature 236 (1987) 520-523, and 328 (1987) 742]. The complete nucleotide sequence of one of these genes is presented here. Comparison of the sequenced gene, LIG1, with the published cDNA(More)
We describe the construction of an RFLP-based genetic map of the white rot fungus Phanerochaete chrysosporium ME446. The map is deduced from the allele distributions of 38 RFLP markers in a test set of 53 meiotically derived haploid recombinants of this strain. The map includes a cellulase gene, a matingtype locus and a family of lignin peroxidase (and(More)
The white rot fungus Phanerochaete chrysosporium is an efficient degrader of lignin. Development of classical genetics in this organism would require several years of work, so an alternative strategy was devised. As in the mapping of human genetic diseases, the approach depends on the presence of interallelic restriction site polymorphism, but differs in(More)
Haploid recombinant progeny of Phanerochaete chrysosporium ME446, genome compositions of which had been defined by RFLP-mapping, vary in their idiophasic behaviour. This allowed us to formulate a model of the sequence of idiophasic activities. One component of this variation, the amount of lignin peroxidase activity, is independent of the allele(More)
