The soft rot Enterobacteriaceae (SRE) Pectobacterium and Dickeya species (formerly classified as pectinolytic Erwinia spp.) cause important diseases on potato and other arable and horticultural crops. They may affect the growing potato plant causing blackleg and are responsible for tuber soft rot in storage thereby reducing yield and quality. Efficient and cost-effective detection and identific...
During late August and early September 2011, stem rot symptoms were observed on adzuki bean plants (Vigna angularis) growing in fields located in Beijing and Hebei Province, China, respectively. In this study, four isolates were obtained from infected stems of adzuki bean plants. Based on their morphology, and sequence and polymerase chain reaction-restriction fragment length polymorphism (PCR-...
A method for the degradation of dioxins by white rot fungi was developed. Degradation of a mixture of 10 kinds of tetra- to octachlorodibenzo-p-dioxins (polychlorinated dibenzo-p-dioxins [PCDDs]) and tetra- to octachlorodibenzofurans (polychlorinated dibenzofurans [PCDFs]), which were chlorinated at 2-, 3-, 7-, and 8-positions of the molecules, by the white rot fungus Phanerochaete sordida YK-6...
A study is described which is unique in that resistance to each of the major diseases which affect production in Merino sheep was measured in the same flock under the same environmental conditions. Results indicated that within the one flock, genetic variation exists for resistance to internal parasites, foot-rot, fleece rot and dermatophilosis. Heritability estimates were similar to those publ...
The spin-energy E rot of a Kerr black hole surrounded by a torus may power emissions in multiple windows. The recently determined true GRB-energy E γ = 3 − 5 × 10 50 erg indicates a minor fraction E j /E rot ≃ 0.1% in baryon poor output, here considered as jets along open magnetic flux-tubes from the horizon to infinity. A major fraction E gw /E rot ≃ 5% is expected in gravitational radiation f...
Incipient decay of wood by brown rot fungi causes measurable strength losses in wood before measurable weight loss occurs. Previous studies have shown that the high levels of strength loss that occur during incipient brown rot decay may be related to loss in hemicellulose. This paper investigates the effect of decay on hemicellulose composition and the relationship to the mechanical properties ...
Soft-rot Enterobacteriaceae (SRE), which belong to the genera Pectobacterium and Dickeya, consist mainly of broad host-range pathogens that cause wilt, rot, and blackleg diseases on a wide range of plants. They are found in plants, insects, soil, and water in agricultural regions worldwide. SRE encode all six known protein secretion systems present in gram-negative bacteria, and these systems a...
Bacteria have been isolated from 10 different strains of Phanerochaete chrysosporium, a white rot fungus which degrades lignocellulosic materials. The investigations showed that one or more bacterial species were always associated with the fungus. Various attempts to eliminate the bacteria on the fungus were unsuccessful. Three different bacterial species were isolated and identified. One of th...
Natural steroidal hormone estrone (E1) was treated with the white rot fungus Phanerochaete sordida YK-624 under ligninolytic condition with low-nitrogen and high-carbon culture medium. E1 decreased by 98% after 5 d of treatment and the activities of ligninolytic enzymes, manganese peroxidase (MnP) and laccase, were detected during treatment, which suggested that the disappearance of E1 is relat...
maize genotypes were screened for host resistance and seed treatment chemicals were evaluated in field to manage fusarium ear rot complex of maize at high- and mid-hill environments in nepal during 2003 and 2004. seven popular maize genotypes along with a susceptible check were used in the host resistance study. the maize genotypes adopted from exotic sources, manakamana-3 and deuti, performed ...
