Rice tungro bacilliform virus (RTBV) together with rice tungro spherical virus (RTSV) is the causal agent for the rice tungro disease. A rapid technique was developed to detect RTBV DNA in the crude extract of freshly collected leaf samples by polymerase chain reaction (PCR). This technique can detect the viral DNA in 1000-fold diluted leaf extract.(More)
Rice tungro, economically the most important viral disease of rice, is a complex disease caused by two morphologically and genomically dissimilar viruses, Rice tungro bacilliform virus (RTBV), a double stranded DNA virus replicating through RNA intermediate and Rice tungro spherical virus (RTSV), a single stranded RNA virus with 3' poly (A) tail. A novel(More)
Conventional antipsychotic agents are not effective against negative symptoms of schizo-phrenia and are also noted for their extrapyramidal side effects. Risperidone is a noval antipsy-chotic agent whose dual antagonism of dopamine and serotonin receptors is believed to underlie its efficacy against negative symptoms and the low incidence of extrapyramidal(More)
