Development of infection with beet western yellows virus in the sugarbeet

Virology, 1972
Abstract Electron microscopy of successively older leaves of sugarbeet ( Beta vulgaris L.) infected with beet western yellows virus (BWYV) revealed the steps in the infection of leaf tissues by the virus and gave some insight into the events leading to viral multiplication in host cells. The sequence of the infection is interpreted as follows. Virus

Yield-limiting potential of Beet western yellows virus in Brassica napus

Australian Journal of Agricultural Research, 2007
Losses in seed yield and quality caused by infection with Beet western yellows virus (BWYV) alone or in combination with direct feeding damage by Myzus persicae (green peach aphid) were quantified in field experiments with Brassica napus (canola, oilseed rape) in the ‘grainbelt’ region of south-western Australia.

Glycosylation of beet western yellows virus proteins is implicated in the aphid transmission of the virus

Archives of Virology, 2005
Beet western yellows virus relies on the aphid M. persicae for its transmission in a persistent and circulative mode. To be transmitted, the virus must cross the midgut and the accessory salivary gland epithelial barriers by a transcytosis mechanism where vector receptors interact with virions.

Weed Hosts of Beet Western Yellows Virus and Potato Leafroll Virus in British Columbia

Plant Disease, 1992
The vegetable production areas of British Columbia were surveyed to determine weed hosts of beet western yellows virus (BWYV) and potato leafroll virus (PLRV). More than 10,000 plant samples were tested for BWYV and PLRV; the enzyme-linked immunosorbent assay was used. Twelve species from five families were infected with BWYV.

Ultrastructure of sugarbeet leaves infected with beet western yellows virus

Journal of Ultrastructure Research, 1972
An electron microscope study of sugarbeet (Beta vulgaris L.) leaves infected with beet western yellows virus (BWYV) revealed isometric particles, 24–30 nm in diameter, in phloem and mesophyll cells. Compared to ribosomes the particles were slightly larger, more deeply stained, and sharper in outline. Many particles showed an electron lucent center. The

The use of monoclonal antibodies to detect beet mild yellowing virus and beet western yellows virus in aphids

Annals of Applied Biology, 1991
SummaryInformation on infectivity of the aphids which invade sugar beet root crops each Spring is required for forecasting incidence and providing advice on control of virus yellows. Monoclonal antibodies, produced in the USA to barley yellow dwarf virus (BYDV) and in Canada to beet western yellows virus (BWYV), were used to distinguish between sugar ...

The detection of beet western yellows virus and beet mild yellowing virus in crop plants using the polymerase chain reaction

Journal of Virological Methods, 1991
Oligonucleotide primers were synthesised corresponding to conserved sequences between three isolates of beet western yellows virus (BWYV), flanking a 913 base fragment of BWYV genomic RNA. Using the polymerase chain reaction (PCR), these primers successfully amplified the target fragment in total RNA extracts from two oilseed rape plants infected with ...

Molecular characterization of two Chinese isolates of Beet western yellows virus infecting sugar beet

Virus Genes, 2010
Beet western yellows virus (BWYV) has previously been reported as an agent of sugar beet yellowing disease in China. In this article, the complete genomic RNA sequences of two Chinese BWYV isolates infecting beet from Inner Mongolia (BWYV-IM) and Gansu (BWYV-GS) were determined and compared with three beet poleroviruses (BMYV, BChV and BWYV-US) and ...

First Report of Beet Western Yellows Virus Infecting Vasconcellea x heilbornii (Caricaceae) in Ecuador.

Plant Disease
Vasconcellea x heilbornii, known as babaco, is a hybrid native to Ecuador grown in small orchards in sub-tropical highland regions. Over the last decade, several viruses have been identified in babaco using high-throughput sequencing (HTS) (Cornejo ...

Beet western yellows virus in phloem of pennycress

Journal of Ultrastructure Research, 1984
The effects of beet western yellows virus on pennycress phloem were investigated using electron microscopy and collecting at intervals after aphid inoculation. Particles were seen in mature sieve elements from the earliest collection date, but they became less numerous in sieve elements of older leaves as the infection progressed.
