Genomic Sequence of a Czech Isolate of Erysimum Latent Virus from Sisymbrium altissimum Open
The Erysimum latent virus (ELV), a tymovirus, was first isolated from several wild and cultivated brassicas in Germany. Its virions were shown to be serologically distinct from those of the turnip yellow mosaic virus (TYMV), which is also …
