Arsenic is a great hazard to the environment since it is a major source of soil and water contamination leading to phytotoxicity. Arsenic caused reduction in seed germination and growth of plants including mung bean (Vigna radiata) causing loss of crop productivity. This investigation evaluates effect of arsenic toxicity in mung bean with an attempt to ameliorate it by the application of curcum...

A number of well characterized legume lectins including the enzymic lectin from Vigna radiata were examined for immunological relatedness. The immunological cross-reactions observed indicate that most of the legume lectins, including Vigna lectin, are evolutionarily closely related proteins. The possibility that these proteins are homologs with enzymic functions is discussed.

Leguminous crops, possessing root nodules, fix and utilize atmospheric nitrogen. They are thus not dependent on industrially fixed nitrogen but add up to 30 kg of nitrogen / hectare to the soil and improve its fertility. Access to mineral nitrogen often limits plant growth, and so symbiotic relationships have evolved between plants and a variety of nitrogen-fixing organisms. These associations ...

A procedure was developed for the partial purification of succinate dehydrogenase from mung bean (Vigna radiata L.) hypocotyls and soybean (Glycine max [L] Merr. v. Ransom) cotyledons. The procedure utilized a Triton X-100 extraction followed by ammonium sulfate precipitation. The final fraction was enriched in two polypeptides with approximate molecular weights of 67,000 and 30,000 daltons, ex...

Two forms of Fd-NADP+ oxidoreductase (FNR) isoproteins have been purified and characterized from the first foliage leaves of 5d-old mung bean (Vigna radiata). They could be separated by either Mono Q HR 515 or ferredoxin (Fd)-Sepharose 48 affinity columns. Based on immunoblot analysis and N-terminal amino acid sequences, one form resembles the FNR purified from photosynthetic tissues of higher ...
