Western Blots Reveal that Grapevine Viruses A and B are Serologically Related

Abstract
Isolates of grapevine virus B (GVB) and grapevine virus A (GVA) were obtained by mechanical transmission from grapevines to Nicotiana benthamiana. Western blot studies of these isolates using various antisera to GVB and GVA showed that they are serologically related.
