Studies on the Purification and Biochemical Properties of BaYMV
Abstract: The Barley Yellow Mosaic disease is an important crop disease spread in the suburbs of Shanghai and coastal arears in East China. A purification procedure of Shanghai isolate of BaYMV was developed using the combination method of organic solvent treatment,ultracentrifugation,sucrose and CsCl densi- ty gradient centrifugation. The isolate showed the existence of two peaks in particle-length distribution (300 nm and 600 nm). SDS-PAGE of purified virus preparation demonstrated one major band of 29kd. A minor b...
