An hypothesis for the role of malic enzyme in symbiotic nitrogen fixation in soybean nodules,dy-state conditions, have shown that while addition of malate stimulated respiration, the effect on N. fixation depended on the concentration of malate and oxygen. At low malate concentrations, N. fixation was stimulated, but at higher malate concentrations (more than 0.5 m. at less than 60 n. O.) N

Eastern Canadian soybean field trials of rhizobial strain NS 1 in two commercial carriers,cific legume inoculants for Atlantic Canada. In 1989–90 strain NS 1, in preliminary small-plot field trials utilizing a non-commercial inoculant carrier, gave seed yields 25% greater than the most popular commercial strain, 532C, in five site-years of tests in Atlantic Canada. In 1991 strain NS 1, i

Mechanism of osmotically regulated N-acetylglutaminylglutamine amide production in ,,that NAGGN may be partly responsible for the osmotic tolerance observed in .. 36% of mutants that were characterized as osmotically sensitive compared to the parent strain, were also found to contain reduced levels of NAGGN. The phenomenon of osmolyte accumulation as it relates to adaptation to other environmental stresses is discussed.

Characterization of , chromosomal genes involved in the regulation of , gene expression in free-livred bp downstream, separated by an AT rich region, an RpoNl/RpoN. transcribed . homologous gene was identified. These ORF–s show significant homology to genes involved in processing, maturation and functional regulation of the hydrogenase complex, previously described in various hydrogen-oxidizing bacteria.

Shoot/root assimilate allocation and nodulation of , seedlings as influenced by shoot light environ was modified by reflection from different colored soil surfaces or by FR reflected from competing plants. The importance of early shoot/root photoassimilate allocation and nodulation may differ according to soil nitrogen availability and moisture content.

Recent developments in , taxonomy,, fatty acid analysis, RFLP and RPD-PCR techniques and phylogenies derived from other genes are in general agreement to the groupings derived by ribosomal sequences. Only a small proportion of nodulated legumes have been sampled for their symbionts and more knowledge is required on the systematics and taxonomy of . and . species.
