Abstract

Common primers which amplify the 3′ terminal genomic RNAs of Allium carla viruses were designed based on the nucleotide sequence of shallot latent virus (SLV), garlic latent virus (GLV) and garlic common latent virus (GCLV). A total of fifteen cDNAs encoding the coat protein (CP) of the carla viruses, including the biologically identified isolates SLV, GLV and GCLV as well as viruses from infected Allium plants cultivated in different parts of the world, were amplified by RT-PCR with the common primers. The cDNAs were then cloned and sequenced. The predicted viral CP amino acid sequence as well as the nucleotide sequence revealed that SLV and GLV, previously considered as separate viruses on the basis of their biological and physical properties, belong to the same species of the genus Carlavirus. Both viruses are clearly differentiated from GCLV. In addition, every SLV and GLV isolate from the Allium plants in Taiwan showed characteristic and common variations in their CP sequences, suggesting the possible presence of geographical variants. However, no apparent sequence variations of SLV and GLV related to their host plant species, including A. sativum, A. wakegi, A. chinense, A. fistulosum, A. cepa and A. ampeloprasum , were observed. These findings suggested that the sequence variations observed in the respective virus isolates do not correlate with the specificity of their infectivities for Allium species.
