Abstract
High molecular weight double-stranded ribonucleic acids (dsRNAs) were detected in two rice cultivars, 'M-201' and 'Saturn', growing in experimental plots and showing virus-like symptoms. Partial sequencing of these dsRNAs indicated that they were related to the genome of Oryza sativa endornavirus (OSV), which has been reported in Japan infecting many rice cultivars. As this virus has not been reported in the US, 50 rice genotypes from the three major rice-breeding programmes were tested. The virus was detected in two additional rice cultivars, 'M-102' and 'Colusa'. Analysis of the pedigree of infected cultivars suggested that the cultivar 'Colusa' was likely the source of the virus which was vertically transmitted to the progeny during the breeding process. The frequency of OSV in the tested cultivars was relatively low, compared with the high virus incidence of this virus reported in Japan. The virus does not appear to cause symptoms in rice and it was efficiently transmitted through seed. © 2010 Blackwell Verlag GmbH.
