Barley yellow dwarf virus-aphid vector interactions associated with virus transmission and vector specificity - 1990 - Printed

44 ref

Barley yellow dwarf virus (BYDV) and their aphid vectors are associated in a variety of complex interactions that influence both virus and aphid survival and spread. As luteoviruses infect and replicate in phloem tissues of plant hosts, it is probable that they can only be transmitted by phloem-feeding aphids. Recent studies have elucidated the circulative route of BYDV through aphid vectors. Aphids ingest BYDV while feeding on phloem of infected plants. Virus acquisition occurs when virus is actively transported by the aphids hindgut cells through the gut wall and is liberated into the body cavity. To be transmitted, virions in the hemolymph must come in
