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 ...

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 ...

Maximizing the detection capability of a beet western yellows virus ELISA system
Journal of Virological Methods, 1984Conditions for maximizing detection of a California isolate of beet western yellows virus (BWYV) were investigated with the double-sandwich enzyme-linked immunosorbent assay (ELISA) system. Within-plate variability was found to account for less than 1% of the total variation observed on individual microtiter plates.

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 ...

A strain of beet western yellows virus in Canterbury, New Zealand
New Zealand Journal of Agricultural Research, 1983Abstract A persistent aphid‐borne virus was isolated from turnip ( Brassica rapa L.) and from sugar beet and fodder beet ( Beta vulgaris L.) plants with yellowing and subsequently from 30 other crop and weed species in 15 plant ...

Assessment of the susceptibility of some potato cultivars to beet western yellows virus
New Zealand Journal of Crop and Horticultural Science, 1991Abstract In greenhouse tests, six potato cultivars were inoculated with a beet western yellows virus (BWYV) isolate from turnips, but no infection was detected. Natural infection of potatoes was tested for in field trials over two seasons. In 1984–85, no infection of 36 ‘Ilam Hardy’ and 12 ‘Iwa’ potato plants with

Development of infection with beet western yellows virus in the sugarbeet
Virology, 1972Abstract 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

Ultrastructure of sugarbeet leaves infected with beet western yellows virus
Journal of Ultrastructure Research, 1972An 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

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.
