CHARACTERIZATION OF BARLEY STRIPE MOSAIC-VIRUS HUNGARIAN STRAIN

Serologically the Hungarian isolate (BSMV-H) proved to be similar to the other BSMV strains and differed from PSLV. Virions of BSMV-H contained three large genomic RNAs and an additional, probably subgenomic RNA. The large RNAs of BSMV-H was highly homologous to the RNAs of BSMV Argentina Mild strain for they hybridized to the cDNA probe prepared from RNAs of BSMV-Am. The small, encapsidated RNA (0.27 x 10(6) d) of BSMV-H hybridized to the full-length clone of RNA gamma of BSMV-ND18 and it is thought to be subgenomic RNA. According to its properties BSMV-H is considered to be a new strain of BSMV.
