Molecular analyses revealed that a virus causing a severe disease of wheat in one field in Southern Germany is closely related to the Nebraska type strain of Soil-borne wheat mosaic virus (SBWMV) and only distantly related to Soil-borne cereal mosaic virus that is widely distributed in Europe. The latter virus was not found in the SBWMV-containing leaf samples. This is the first report of the occurrence of SBWMV in Germany, and perhaps in all of Europe, which has been confirmed on the molecular level. 相似文献

Summary Potato mop-top virus particles, purified from systemically infectedNicotiana benthamiana plants and then disrupted by heating with sodium dodecyl sulphate and 2-mercaptoethanol, contained only a single polypeptide of Mr 19 100 detectable by polyacrylamide gel electrophoresis. Single-stranded RNA preparations from virus particles, when subjected to electrophoresis in an agarose gel containing methylmercuric hydroxide as a denaturant, were shown to contain approximately equal proportions of three RNAs of 6.5, 3.2 and 2.5 kb. Double-stranded RNA preparations extracted from systemically infectedN. benthamiana leaves or from locally infectedN. debneyi leaves, was shown by polyacrylamide gel electrophoresis to contain a major species of 3.2 kbp and two minor species of 6.5 and 2.4 kbp. 相似文献
