| biological properties and molecular characterization of beet chlorosis virus (bchv). | two distinct viruses belonging to the polerovirus genus, in the family luteoviridae, have been described as being able to induce mild yellowing on sugar beet: beet mild yellowing virus (bmyv) and more recently, beet chlorosis virus (bchv). we have analysed biological properties and molecular organisation of two strains of bchv, one collected in england and the second from california. the biological data suggested that bchv displayed a narrower host range compared to bmyv and beet western yellows ... | 2002 | 12038685 |
