Stem necrosis disease caused by Tobacco streak virus (TSV), first recognized in 2000, has emerged as a potential threat to peanut (Arachis hypogaea) in southern states of India. The virus induces severe necrosis of shoots leading to death of the plant, and plants that survive are malformed, with ...

Since the first outbreak of Tobacco streak virus (TSV), genus llarvirus as sunflower necrosis disease (SND) on sunflower and peanut stem necrosis disease (PSND) on groundnut in late 1990s, the virus has been a subject of much research in India. This review considers main features of TSV in India....

In the present study, high titred polyclonal antibodies were produced against synthetic AFB1-lys and developed a simple indirect competitive (IC)-ELISA for quantitative estimation of AFB1-lys adducts in human serum albumin. IC-ELISA was validated by testing 250 blood samples that include 85 HBV p...

Helicoverpa armigera (Hubner) (Noctuidae: Lepidoptera), commonly known as legume pod borer, is a major insect pest of legume crops in the semi-arid tropics. A baculovirus of type nucleopolyhedrovirus (NPV) was isolated from this insect during natural epizootics at ICRISAT. Patancheru (Andhra Prad...

Aflatoxin B1 is a carcinogen produced by Aspergillus flavus and a few related fungi that are often presentin many food substances. It interacts synergistically with Hepatitis B or C virus (HBV, HBC) infection,thereby increasing the risk of hepatocellular carcinoma (HCC). The G to T transversion a...
