| variation in the transmission of barley yellow dwarf virus-pav by different sitobion avenae clones in china. | fourteen sitobion avenae fabricius (hemiptera: aphididae) clonal lines (clones) originating from china were tested for their ability to transmit bydv-pav (one isolate from belgium and another from china) using wheat plants. by sequence analysis, the coat protein gene of bydv-pav-be was distinguishable from bydv-pav-cn. all of the clones could transmit bydv-pav, and the transmission varied from 24.42% to 66.67% with bydv-pav-be and from 23.55% to 56.18% with bydv-pav-cn. these data suggest that s ... | 2013 | 23911295 |
