| rice yellow mottle virus in madagascar and in the zanzibar archipelago; island systems and evolutionary time scale to study virus emergence. | rice yellow mottle virus (rymv), of the genus sobemovirus, is a major threat to rice cultivation in africa. long range transmission of rymv, difficult to study experimentally, is inferred from a detailed analysis of the molecular diversity of the virus in madagascar and in the zanzibar archipelago (zanzibar and pemba islands; tanzania) compared with that found elsewhere in africa. a unique successful introduction of rymv to madagascar, which is ca. 400 km from mainland africa, contrasted with re ... | 2013 | 23123216 |
