Studies on the Xinjiang isolate of the cauliflower mosiac virus
Publication date:
According to serology, inclusion bodies, morphology and some physicochemical properties of the virus, the isolate 63-3 (designated as Xinjiang isolate) from cabbage (Brasica olercea var. capitata L.) belongs to culiflower mosaic virus (CaMV) which contains DNA. The serological relationship has been shown between the Xinjiang isolate and the known Campbell strain of CaMV. In the infected leaves, besides the chracteristic types of inclusion bodies, there were also intracellular bodies composed of particles about 15-18 nm in diameter, which has not been reported in caulimo-virus. Purified virus of the Xinjaian isolate consists of spherical particles about 50 nm in diameter, its sedimentation coefficient has been determined to be 200-220S. The DNA content of Xinjiang isolate is 16-18 percent as determined by diphenylamine method. Taken together, these characteristics are smilar to the physieochemical propertis of CaMV. It seems that the Xinjiang isolate resembles closely the New York 8153 of CaMV in respect of trasmission by aphid Myzus persicae and formation of laocal lesions on Datura stramonium. [AS]
