| selective constraints, molecular recombination structure and phylogenetic reconstruction of isometric plant rna viruses of the families luteoviridae and tymoviridae. | in an effort to enhance the knowledge on molecular evolution of currently the known members of the families luteoviridae and tymoviridae, in-depth molecular investigations in the entire genome of 147 accessions retrieved from the international databases, were carried out. two algorithms (recco and rdp version 3.31β) adapted to the mosaic structure of viruses were utilized. the recombination frequency along the sequences was dissected and demonstrated that the three virus genera of the family lut ... | 2010 | 20933049 |
| the complete nucleotide sequence of the barley yellow dwarf gpv isolate from china shows that it is a new member of the genus polerovirus. | the complete nucleotide sequence of the ssrna genome of a chinese gpv isolate of barley yellow dwarf virus (bydv) was determined. it comprised 5673 nucleotides, and the deduced genome organization resembled that of members of the genus polerovirus. it was most closely related to cereal yellow dwarf virus-rpv (77% nt identity over the entire genome; coat protein amino acid identity 79%). the gpv isolate also differs in vector specificity from other bydv strains. biological properties, phylogeneti ... | 2009 | 19551470 |
