Wood-decaying fungi in the phylum Basidiomycota play a significant role global carbon cycle, as they decompose deadwood effectively. Fungi may compete for utilizable substrate and growth space by producing soluble metabolites releasing volatile organic compounds (VOCs). We determined of wood (Scots pine or Norway spruce) on generation hyphal biomass, secreted enzyme activities, decomposition ra...
ABSTRACT Genetic variation and variation in aggressiveness in Phialophora gregata f. sp. sojae, the cause of brown stem rot of soybean, was characterized in a sample of 209 isolates from the north-central region. The isolates were collected from soybean plants without regard to symptoms from randomly selected soybean fields. Seven genotypes (A1, A2, A4, A5, A6, M1, and M2) were distinguished ba...
Brown-rot fungi such as Postia placenta are common inhabitants of forest ecosystems and are also largely responsible for the destructive decay of wooden structures. Rapid depolymerization of cellulose is a distinguishing feature of brown-rot, but the biochemical mechanisms and underlying genetics are poorly understood. Systematic examination of the P. placenta genome, transcriptome, and secreto...
Interaction among and between mushroom / white rot and brown rot fungi or soft rot fungi, studied by the dual culture plate assays showed that the outcome of a specific interaction was strongly dependent on the two organisms concerned. Phanerochate chrysosporium as one of the partner in dual cultures, invariably scored grade 2 for colony interaction as it overgrew and covered the colony of othe...
Wood-degrading brown rot fungi are essential recyclers of plant biomass in forest ecosystems. Their efficient cellulolytic systems, which have potential biotechnological applications, apparently depend on a combination of two mechanisms: lignocellulose oxidation (LOX) by reactive oxygen species (ROS) and polysaccharide hydrolysis by a limited set of glycoside hydrolases (GHs). Given that ROS ar...
Various aspects of the participation of Fenton chemistry in biology and medicine are reviewed. Accumulated evidence shows that both hydroxyl radical and ferryl [Fe(IV)=O]2+ can be formed under a variety of Fenton and Fenton-like reactions. Some examples of metal-independent hydroxyl radical production are included. Extracellular Fenton reaction is illustrated by the white rot and brown rot wood...
Basidiomycota brown rot fungus ( Fomitopsis pinicola ) and two white fungi Phlebia radiata , Trichaptum abietinum were cultivated on thin slices of spruce wood individually in interspecies combinations. Within 12 months, F. substantially decomposed observed as mass loss, also three-species However, through hyphal interactions negatively affected the brown-rot indicative iron reduction capacity ...

Balloon flower (Platycodon grandiflorum) is a kind of mountain herbs whose roots have restorative properties and the cultivating acreage of balloon flower has been steadily increasing in Korea. More frequent rain and high amount of rainfalls as a result of climate changes predisposed balloon flower to the outbreaks of root rot at high-density cultivation area in recent years. Root crowns were u...
