Fungi Isolated from Pine Wood Nematode, Its Vector Japanese Pine Sawyer, and the Nematode-Infected Japanese Black Pine Wood in Korea
Pine tree death caused by pine wood nematode (PWN) involves phoretic relationships between PWN and its vector Japanese pine sawyer beetle (JPS). In an effort to understand the diversity of fungi involved in PWN life cycle, a total of 176 fungal isolates were collected from PWNs, adults and larvae of JPS, PWN-diseased Japanese black pine that was cut down in 2005 at Jinju, Korea. Based on micros...
متن کاملThe expressed genes of Japanese red pine (Pinus densiflora) involved in the pine wilt disease severity
Background Japanese pine trees have been severely damaged by the pine wilt diseases, and hardly been keeping the productive forest in Japan. The pine wood nematode,Bursaphelenchus xylophilus, is a virulent pathogen in Japan, while it is originated and is an endemic one in the United State [1]. The diseases have now been spread not only in East Asia but also in a part of Europe. The Japanese Gov...
متن کامل(Article) Stem/branch Maintenance Respiration of Japanese red pine stand
Stem/branch maintenance respiration for a stand of Japanese red pine (Pinus densiflora) during the dormant season was examined using an open flow system. The stem/branch respiration rates per unit of volume were closely related to the thickness of the stems and branches, e.g. it decreased with increasing diameter (p<0.0001). When the respiration rates on the various positions were regressed aga...
متن کاملDisplacement Chromatography on Synthetic Ion - exchange Resins
In Part 1 of this series of papers (Partridge & Westall, 1949) it was shown that, whilst the baseexchange resin Zeo Karb 215 may be used with success for the separation of the neutral and acidic amino-acids, certain difficulties arise when the separation of basic substances is attempted. These difficulties were traced to the phenolic hydroxyl groups of the resin. Resins of the sulphonated pheno...
متن کاملInfluence of Uron Resins on the Performance of Uf Resins as Adhesives for Plywood
Uron resin, a kind of urea-formaldehyde (UF) resin containing much more uron structure, were prepared. Several modi ed UF resins were obtained from mixing uron resins with normal UF resins as well as synthesizing UF resin with uron resin as raw material. is work demonstrated that the introducing of the uron structure reduced free formaldehyde content of UF resin and formaldehyde emission levels...
