大麦黄矮病毒株系间分子变异与系统进化关系研究
Studies on the relationship between molecular variation and phylogene among different strains of barley yellow dwarf virus
摘要
Abstract
Forty-five complete sequences of barley yellow dwarf virus ( BYDV) genome were analyzed with multiple alignments, and the results showed that there are two different genome structure types of BYDV. Two phylogenetic trees of BYDV were established based on 45 complete genomes and 166 coat protein (cp) genes sequences, and the results showed that PAV strains could be divided into three subgroups, and the PAV isolates from China were different from the isolates from Europe or America. The MAV strain could also be divided into three subgroups, and the MAV ( one of three subgroups in USA) held high similarity with GAV (in China) in genome sequences. 33 CP amino acid sites were found completely conserved in the same strains but were highly variable among different strains. Strain-specific sites of PAV, SGV, GPV were found by sequencing analysis, but no strains-specific variable site was found between GAV and MAV, indicating that the GAV might be one subgroup of MAV.关键词
