| Abstract: | The biological and serological properties of two Japanese barley mild mosaic virus (BaMMV) strains (BaMMV-Kal and BaMMV-Nal) and a German BaMMV strain (BaMMV-M) were compared. Mechanical inoculation experiments showed that these three strains differed from one another in their ability to infect specific barley cultivars. BaMMV-Kal and BaMMV-M caused similar symptoms, but BaMMV-Nal clearly differed from them in its symptoms on some barley cultivars. The three BaMMV strains efficiently infected barley plants at 15°C, whereas at 20°C BaMMV-Kal and BaMMV-M also infected many plants but BaMMV-Nal infected only a few. BaMMV-Kal and BaMMV-M were indistinguishable by ELISA, while BaMMV-Nal was distinguished from both. The biological and serological variability reported shows that BaMMV occurs as two distinct strains in Japan. |
