Interactions Between Beet necrotic yellow vein virus and Beet soilborne mosaic virus in Sugar Beet
Beet necrotic yellow vein virus (BNYVV) and Beet soilborne mosaic virus (BSBMV) are members of the genus Benyvirus (9). Both viruses infect members of the family Chenopodiaceae, most notably sugar beet (Beta vulgaris L.), and are transmitted by the plasmodiophorid, Polymyxa betae (1,2). BNYVV infection causes rhizomania disease in sugar beet (4,21); however, BSBMV infection does not (28). BSBMV...
متن کاملNucleotide Sequence of Beet Necrotic Yellow Vein Virus RNA-1
The complete nucleotide sequence of beet necrotic yellow vein virus RNA-1 is presented. The R N A molecule is 6746 nucleotides long excluding the poly(A) tail and has one long open reading f lame encoding a polypeptide of M r 237 389. The 3' terminal 60 residues of BNYVV RNA-1 display extensive sequence homology with the corresponding portions of BNYVV RNA-2, -3 and -4. Addi t ional 3' terminal...
متن کاملNucleotide Sequence of Beet Necrotic Yellow Vein Virus RNA-2
The complete nucleotide sequence of beet necrotic yellow vein virus (BNYVV) RNA-2 has been determined from a study of cloned cDNA. The RNA sequence is 4612 nucleotides in length, excluding the poly(A) tail. There are six long open reading frames (ORFs) in the sequence. The viral coat protein cistron is the ORF nearest to the 5' terminus and the coat protein amber termination codon is followed b...
متن کاملSuppression of Resistance-Breaking Beet necrotic yellow vein virus Isolates by Beet oak-leaf virus in Sugar Beet
Beet necrotic yellow vein virus (BNYVV) is a member of the genus Benyvirus (21,22) and causes the disease known as rhizomania. It often is reported to be the most important sugar beet (Beta vulgaris L.) virus (17). BNYVV is transmitted by the plasmodiophorid, Polymyxa betae Keskin (1,2,6). In the United States, the virus first was identified in California in 1984 (5) but now occurs in every maj...
متن کاملNucleo-cytoplasmic shuttling of the beet necrotic yellow vein virus RNA-3-encoded p25 protein.
The protein p25 encoded by beet necrotic yellow vein virus (BNYVV) RNA-3 is involved in symptom expression of infected plants. Confocal microscopy analysis of wild-type and mutated p25 fused to GFP and transiently expressed in BY-2 tobacco suspension cells identified a nuclear localization signal (NLS) in the N-terminal part of the protein. Functionality of the NLS was confirmed by pull-down as...
