ABSTRACT
Methods of ELISA, nonradioactive molecular hybridiz ation and RT-PCR were applied in the detection of rice grassy stunt virus (RGSV ). The detection sensitivity of indirect ELISA using antiserum against fusion p rotein GST-NC was 1 mg of infected leaves or 84 ng of purified virus. The metho d of dot hybridization using NC, a DIG-labelled DNA probe was 50 μg diseased l e aves, or 6 ng purified preparations. The detection endpoint of RT-PCR was 10 μg diseased leaves, or 2 ng purified virus preparation. Comparisons of sensitivit y and maneuverability were made among these methods.
