Symbiotic Bradyrhizobium japonicum reduces [N.sub.2]O surrounding the soyabean root system via nitrous oxide reductase
Article Abstract:
[N.sub.2]O reductase activity in soybean nodules formed with Bradyrhizobium japonicum was evaluated from [N.sub.2]O uptake and conversion of [sup.15.N]-[N.sub.2]O into [sup.15.N]-[N.sub.2]. Results indicate that the conversion of [N.sub.2]O to [N.sub.2] depends exclusively on the respiratory [N.sub.2]O reductase and that soybean roots nodulated with B. japanicum carrying the 'nos' genes are able to remove very low concentration of [N.sub.2]O.

Levels of polyamines and kinetic characterization of their uptake in the soybean pathogen Phytophthora sojae
Article Abstract:
The polyamine uptake kinetics in Phytophthora sojae zoospores is characterized and endogenous polyamines in hyphae, zoospores, and soybean roots are determined. Inhibition of polyamine uptake might reduce the fitness of the zoospore along with subsequent developmental stages that precede infection.

A novel saponin hydolase from Neocosmospora vasinfecta var. vasinfecta
Article Abstract:
Saponins are glycosides that are widely distributed among plants and a soybean saponin hydrolease from neocosmospora vasinfecta was isolated for studies. Results indicate that the enzyme recognizes the fine structure of the carbohydrate moiety of soya-saponin in its catalytic reaction.
