Abstract
, was identified in alfalfa samples originating from Sudan, northern Africa. Here, we report on the identification and complete genomic sequence of an AVS isolate found in 7-day-old seedlings grown from alfalfa seeds acquired from China. The Chinese isolate of AVS differed in its nucleotide sequence from the Sudanese isolate by 8.6%. The detection of AVS in alfalfa seedlings developed from the germinated seeds may indicate a potential role of seed transmission in the distribution of this virus. The results obtained suggest that AVS may be far more widespread than previously thought.
