| diversity of partial rna-dependent rna polymerase gene sequences of soybean blotchy mosaic virus isolates from different host-, geographical- and temporal origins. | infection of soybean by the plant cytorhabdovirus soybean blotchy mosaic virus (sbbmv) results in significant yield losses in the temperate, lower-lying soybean production regions of south africa. a 277 bp portion of the rna-dependent rna polymerase gene of 66 sbbmv isolates from different: hosts, geographical locations in south africa, and times of collection (spanning 16 years) were amplified by rt-pcr and sequenced to investigate the genetic diversity of isolates. phylogenetic reconstruction ... | 2018 | 29383590 |
