Profenofos 50% EC (curacron 50 EC) is a hazardous pesticide commonly used in agriculture is also an important contaminant of environment. Its presence in biological system has gained importance due to bioaccumulation in food chain. The phyto-toxic effect of profenofos was assessed based on the biochemical parameters (Shoot and Root) of seedlings (Amino acids, Protein, Sugar, DNA and RNA) of the...

In a field experiment, the effect of enhanced UV-B radiation (simulating 20% ozone depletion at Allahabad, 20 degrees 47' N latitude) was studied on two cultivars of Vigna radiata L. with various levels of mineral nutrients (N and P). Study showed decrease in total biomass accumulation, harvest index, RSR and yield after exposure with enhanced level of UV-B. RGR and CGR also showed decline afte...

To check for the presence of Em-like proteins in seeds of the leguminous tree Robinia pseudoacacia L. (black locust), a cDNA library constructed from mRNA isolated from developing seeds was screened using radiolabeled cDNA encoding the Em protein from Vigna radiata as a probe. Sequence analysis of the identified cDNA clones revealed two classes of Em proteins in Robinia. The nucleotide sequence...

Proton-translocating ATPase (H(+)-ATPase) was purified from mung bean (Vigna radiata L.) roots. Treatment of this enzyme with the arginine-specific reagent 2,3-butanedione in the presence of borate at 37 degrees C (pH 7.0), caused a marked decrease in its activity. Under this condition, half-maximal inhibition was brought about by 20 millimolar 2,3-butanedione at 12 minutes. MgATP and MgADP, th...
