and to be colonized by arbuscular mycorrhiza (AM) fungi (Harrison, 1997). Often, nodule formation by a Isoforms of endochitinase in soybean were studied in given bacterial strain is restricted to only a few host plant relation to root symbiosis. Five selected cultivars difgenera, and varieties of a given legume species may differ fering in their nodulation potential were inoculated in nodule fo...

MATERIALS AND METHODS Sulfate translocation in soybean (Glycine max L. Merr) was investigated. More than 90% of the sulfate entering the shoot system was recoverable in one or two developing trifoliate leaves. In young plants, the first trifoliate leaf contained between 10 to 20 times as much sulfate as the primary leaves, even though both types of leaf had similar rates of transpiration and ph...

For the molybdoenzymes synthesis as the nitrogenase, the molybdenum, in its most stable form, the molybdate, must be transported inside the cell. In Bradyrhizobium japonicum, the modABC genes code for a high-affinity ABC-type molybdate transporter. This work allowed to study the effect of inoculation of soybean plants with strains affected in the molybdate transport. modA and modB mutants, unab...

Sulfentrazone has excellent soil activity on many small-seeded broadleaf weeds, however, soybean injury in "eld experiments has been noted under certain environmental conditions. Injury levels in these "eld experiments have appeared to di!er in severity among soybean cultivars. Growth chamber studies were initiated with the objective of examining the suspected di!erences in tolerance among soyb...

To examine the neuroprotective effects of Glycine max, we tested its protection against the glutamate-induced toxicity in primary cortical cultured neurons. In order to clarify the neuroprotective mechanism(s) of this observed effect, isolation was performed to seek and identify active fractions and components. From such fractionation, two triterpene glycosides, 3-O-[α-l-rhamnopyranosyl(1-2)-β-...

Seed health testing by studying the seed-borne fungi of soybean seeds is an important step in the management of the seed-borne diseases. In the present study seed-borne fungi was studied by using agar plate method. A number of seed-borne fungal species was isolated from the agar plate. These seed-borne fungal sps. were Aspergillus niger, A. flavus, A. fumigatus, Chaetomium globosum, Curvularia ...
