| detection and nucleotide analysis of rna5 of beet necrotic yellow vein virus isolated in china. | using the rt-pcr method, five isolates of beet necrotic yellow vein virus from china were used for the rna5 genomic component detection and sequence analysis. the result showed that rna5 was only found in the isolates from baotou and hohhot, but not in those of xingjiang, helongjiang, and wulate of inner mongolia. the rna5 components had 1338 nucleotides and 1358 nucleotides in the length of baotou and hohhot isolates, respectively, in which the single open reading frame (orf) encoding for a pro ... | 1999 | 11037951 |
| phylogenetic analysis of beet necrotic yellow vein virus isolates from china. | a survey detected beet necrotic yellow vein virus (bnyvv) infection in six chinese sugar-beet-growing regions. to study the diversity of virus isolates among the regions, nucleotide sequences of four proteins, namely cp, p25, p31, and p26, were determined and the amino acid sequences thus deduced were analyzed using sequence alignments and the phylogenetic method, respectively. amino acid sequence analysis of cp revealed a-type isolates in harbin, hohhot, baotou, wuwei, and jiuquan and b-type is ... | 2008 | 18224433 |
