Identification of a Novel Isolate of Alfalfa virus S from China Suggests a Possible Role of Seed Contamination in the Distribution of the Virus
Recently, alfalfa virus S (AVS), a new species in the family Alphaflexiviridae, 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 acqui...

| Zusammenfassung: | Recently, alfalfa virus S (AVS), a new species in the family Alphaflexiviridae, 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 |
