Richard E. Sandersiency. However, the non-ideal gas thermodynamic in these cycles may affect the flow properties critically, necessitating the research on the area of non-ideal compressible fluid dynamics (NICFD). Thus, there is a necessity for simulation tools that can accurately predict fluid flows with non-ideal f

Host range, RFLP, and antigenic relationships between , strains and , sp. NGR234, cultivar specificity genes, ., was monomorphic. Using antisera against whole cells of three . strains and NGR234, we separated the 11 strains into four serogroups. The anti-NGR234 sera reacted with a single . strain, USDA191. Only one serogroup, which included USDA192, USDA201, USDA217, and USDA257

Rapid identification of , species based on cellular fatty acid analysis,s could be divided into clusters corresponding to the six species. Fatty acid profiles for each species were developed and these correctly identified at least 95% of the strains belonging to each species. A dendrogram is presented showing the relationships between . species based on fatty acid compo

Synthesis, release, and transmission of alfalfa signals to rhizobial symbionts,way and into the flavonoid pathway via chalcone synthase is controlled by complex .-acting sequences and .-acting factors which are not completely understood. Even less information is available on molecular regulation of the two other biosynthetic pathways that produce trigonelline and stachydrine.

Role of rhizobial lipo-oligosacharides in root nodule formation on leguminous plants,ion of nodulation in pea and, if applied in excessive amounts to a legume, can prevent nodulation and thereby might play a role in competition. During our studies on the biosynthesis of lipo-oligosaccharides, we discovered that, besides the lipo-oligosaccharides, other metabolites are synthesized .
