| properties of a virus isolated from vernonia amygdalina del. in lagos, nigeria. | a previously uncharacterized virus tentatively named vernonia green vein-banding virus (vgvbv) was isolated from vernonia amygdalina del. ("bitterleaf") from lagos, nigeria. the virus was mechanically transmissible but had a narrow host range restricted to nicotiana benthamiana, chenopodium quinoa and c. amaranticolor. it was also transmissible in a non-persistent manner by myzus persicae. the virus was purified from n. benthamiana and about 750 nm long flexuous rod-shaped particles were observe ... | 2004 | 15745049 |
| attributes of bean yellow mosaic potyvirus transmission from clover to snap beans by four species of aphids (homoptera: aphididae). | after characterization of the natural spread of necrosis-inducing bean yellow mosaic potyvirus (family potyviridae, genus potyvirus, bymv(n)), nonpersistently transmitted from clover, trifolium repens l., to an adjacent field of snap bean, phaseolus vulgaris l., in western oregon, we established a study site enabling us to investigate the virus reservoir, to observe en masse transmission of bymv(n) to bean plants, and to identify aphid species associated with virus spread. colonies of myzus pers ... | 2005 | 16539099 |
