Isolation and Identification of Barley Mild Mosaic Virus Occurring in Southern Korea

Barley mild mosaic virus (BaMMV-Kor) was isolated from the southern part of Korea, and by mechanical inoculation onto barley cultivars, purification and production of antibody. BaMMV-Kor purified form infected plants were filamentous particle, with 13 nm in diameter and 250∼300 nm and 500∼650 nm in length. Antibody of BaMMV-Kor was made by injecting the purified virus to the muscle of a rabbit. In gel-diffusion test, antibody to BaMMV-Kor created spur with BaMMV-Kal and BaMMV-M, but did not make spur with BaMMV-Kor infected New Golden, Ishukushirazu, Joshushiro Hadaka and Misato Golden, but did not infect Kashimamugi, Chikurin Ibaraki 1 and Mokusekko 3. In Korean barley cultivars, BaMMV-Kor infected most of the covered barley cultivars, but did not infect Saeolbori. It also infected naked barley cultivars except Chalbori and Hinssalbori. And all the beer barley cultivars were infected by BaMMV-Kor. BaMMV-Kor had two RNAs, RNA 1 (7.5 Kb) and RNA 2 (3.5 Kb), and coat protein (33 KDa).
