Identification of Oryza sativa endornavirus in rice genotypes from breeding programmes in the United States

With 1 figure and 1 table 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...
