Genetics of resistance to beet western yellows virus in lettuce
Plant Pathology, 1991Resistance to beet western yellows virus (BWYV) in the lettuce cultivars Burse 17 and Crystal Heart was controlled by a single recessive gene designated bwy. ELISA tests showed that resistant plants were not immune to infection by BWYV, and may develop some mild symptoms.

Beet western yellows virus in phloem of pennycress
Journal of Ultrastructure Research, 1984The 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.

Molecular evidence for the occurrence of beet western yellows virus on chickpea in Morocco
European Journal of Plant Pathology, 1997A luteovirus isolate infecting chickpea in Morocco was experimentally transmitted by Myzus persicae to Physalis floridana, on which it produced mild symptoms. When tested in western blots against antisera to known legume luteoviruses, this isolate reacted strongly to beet western yellows virus (BWYV) antiserum, moderately to bean leafroll virus ...

Beet western yellows virus infects the carnivorous plant Nepenthes mirabilis
Archives of Virology, 2016Although poleroviruses are known to infect a broad range of higher plants, carnivorous plants have not yet been reported as hosts. Here, we describe the first polerovirus naturally infecting the pitcher plant Nepenthes mirabilis. The virus was identified through bioinformatic analysis of NGS transcriptome data.

FIRST REPORT OF BEET WESTERN YELLOW VIRUS ON PEPPER IN CHINA
Journal of Plant Pathology, 2015Beet western yellows virus (BWYV, genus Polerovirus, family Luteoviridae) infects Beta vulgaris, Raphanus sativus, Capsella bursa-pastoris plus a number of common weed species. In August 2014, pepper plants (Capsicum frutescens) showing mosaic and crinkling of the young leaves were observed in greenhouses in Tangshan city, Hebei province (China ...

Incidence and Effects of Beet Western Yellows Virus in Western Oregon Sugarbeet Seed Crops
Journal of Sugarbeet Research, 1999A 1986 to 1995 survey of beet western yellows luteovirus (BWYV) in western Oregon crop and weed species demonstrated that BWYV was endemic in at least 30 plant species. Because sugarbeet-seed crops (Beta vulgaris L.) were sometimes perceived as the primary western Oregon source of BWYV inoculum, we sought to examine all components of the inoculum ...

Ultrastructural changes in chloroplasts of lettuce infected with beet western yellows virus
Physiological Plant Pathology, 1978Abstract An electron microscope examination of lettuce plants infected with beet western yellows virus (BWYV) showed that the interveinal leaf-yellowing disease symptoms were associated with the degeneration of the chloroplasts. The disappearance of grana stacks, stroma lamellae and the appearance of abnormally large starch grains in chloroplasts was

Resistance to Beet Western Yellows Virus Among Forage Brassicas
Plant Disease, 1990Fourteen forage Brassica cultivars representing four species were evaluated for resistance to beet western yellows virus (BWYV), potato leafroll virus (PLRV), and the tomato yellow top strain of PLRV (PLRV-TY) under field exposure. Incidence of field infection with BWYV ranged in several susceptibility classes from less than 2 to 100%.

Yield-limiting potential of Beet western yellows virus in Brassica napus
Australian Journal of Agricultural Research, 2007Losses 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.

Beet western yellows virus in border parenchyma cells of Pennycress
Journal of Ultrastructure Research, 1985Abstract Beet western yellows virus in vein border parenchyma cells of Pennycress leaves induces some unusual cellular modifications, particularly to the cytoplasmic organelles. Relatively advanced stages of infection were examined in leaves 4 weeks after aphid inoculation with the virus.
