CHARACTERIZATION AND RNA2 NUCLEOTIDE SEQUENCE OF BROAD BEAN WILT VIRUS 2 ISOLATE P158

Broad bean wilt virus 2 (BBWV2) isolate P158 was characterized and the complete nucleotide sequence of viral genomic RNA2 was determined. P158 has 30 nm diameter isometric particles. Double immunodiffusion test suggested that P158 has high antigenicity homology with BBWV2 isolate B935. SDS\|PAGE result showed that the coat protein of P158 was comprised of two types of polypeptide with molecular weight of 44.7 kD a...  (本文共5页) 阅读全文>>
