Beet western yellows virus-associated RNA: an independently replicating RNA that stimulates virus accumulation. [PDF]

Proceedings of the National Academy of Sciences, 1993
Infections of plants by subviral RNA agents, alone or in association with virus genomic RNA molecules, are well known. The ST9 strain of beet western yellows virus encapsidates not only the 5.6-kilobase genomic RNA that is typical of luteoviruses, but also a 2.8-kilobase-associated RNA that has a distinct nucleotide sequence. The ST9-associated RNA has

Survey of Faba Bean («Vicia faba» L.) Virus Diseases in Ethiopia

Phytopathologia Mediterranea, 2007
Surveys conducted in 1996 and 1997 to assess the status of virus diseases affecting faba bean in the major growing areas of Ethiopia indicated that leaf yellowing, rolling, necrosis and stunting were the most common disease symptoms. The highest visually-

Nucleotide sequence of beet western yellows virus RNA

Nucleic Acids Research, 1988
The nucleotide sequence of the genomic RNA (5641 nt) of beet western yellow virus (BWYV) isolated from lettuce has been determined and its genetic organization deduced. The sequence of the 3'terminal 2208 nt of RNA of a second BWYV isolate, obtained from sugarbeet, was also determined and was found to be very similar but not identical to that of the ...

Beet Yellows Virus and Beet Western Yellows Virus Isolated from Spinach and Fodder Beet Plants Affected by Yellowing Diseases

Japanese Journal of Phytopathology, 1977
Yellowing diseases of spinach (Spinacia oleracea) and fodder beet (Beta vulgaris var. raga) were found to occur in Kanto area. The diseases were shown to be caused by beet yellows virus (BYV) or beet western yellows virus (BWYV). BYV was not transmitted by sap inoculation, but was transmitted from diseased fodder beet to spinach, Swiss chard (B ...

Biological and Molecular Characterization of an American Sugar Beet-InfectingBeet western yellows virusIsolate [PDF]

Plant Disease, 2008
Three aphid-transmitted viruses belonging to the Polerovirus genus, Beet mild yellowing virus (BMYV), Beet chlorosis virus (BChV), and Beet western yellows virus (BWYV), have been described as pathogens of sugar beet. We present the complete biological, serological, and molecular characterization of an American isolate of Beet western yellows virus ...

Discovery of a Small Non-AUG-Initiated ORF in Poleroviruses and Luteoviruses That Is Required for Long-Distance Movement. [PDF]

, 2015
Viruses in the family Luteoviridae have positive-sense RNA genomes of around 5.2 to 6.3 kb, and they are limited to the phloem in infected plants. The Luteovirus and Polerovirus genera include all but one virus in the Luteoviridae.

Present status of some virus diseases affecting legume crops in Tunisia, and partial characterization of Chickpea chlorotic stunt virus

Phytopathologia Mediterranea, 2011
Field surveys were conducted in Tunisia during the 2005‒2006, 2006‒2007 and 2009‒2010 growing seasons to identify viruses which produce yellowing, reddening and/or stunting symptoms of chickpea, faba bean and pea crops.

Mechanical Unfolding of the Beet Western Yellow Virus −1 Frameshift Signal [PDF]

Biophysical Journal, 2011
Using mechanical unfolding by optical tweezers (OT) and steered molecular dynamics (SMD) simulations, we have demonstrated the critical role of Mg(2+) ions for the resistance of the Beet Western Yellow Virus (BWYV) pseudoknot (PK) to unfolding. The two techniques were found to be complementary, providing information at different levels of molecular ...
