Premature yellowing of sugar beet and lettuce has been noticed for many years in Israel. Many of these plants were found to be infected with beet western yellows virus (BWYV), based on aphid transmission to indicator hosts, serology (double-sandwich enzyme-linked immunosorbent assay [ELISA]), and immunosorbent electron microscopy (ISEM), where isometric particles resembling BWYV virions were observed. BWYV was also detected in turnip, radish, mangold, and in some widespread weeds.
