Data indicating that strains of . and . colonizing specific cultivars of sugarcane as endophytes make a significant contribution to the nitrogen economy of this crop improves the prospects that similar associative syste

Rhizobial communication with rice roots: Induction of phenotypic changes, mode of invasion and exteial competition and fix nitrogen which becomes directly available to the legume plant. It has been a long-standing goal in the field of biological nitrogen fixation to extend the nitrogen-fixing symbiosis to non-nodulated cereal plants, such as rice. To achieve this goal, extensive knowledge of the

Strategies for increased ammonium production in free-living or plant associated nitrogen fixing bacnterference with the mechanisms by which ammonium inhibits either nitrogenase synthesis or activity. These aspects of nitrogen fixation have been best studied in diazotrophic Proteobacteria and Cyanobacteria and those of the former are reviewed in this paper. Ammonium assimilation by glutamine synth

Genetics of , with respect to ammonium transport, sugar uptake, and chemotaxis,l and genetic data are reported on the transport of ammonium and methylammonium in . cells. Ammonium excreting . mutants reported so far appear to result from alterations in genes encoding for enzymes involved in ammonium assimilation. Solid genetic evidence is given on the occurrence of a postulate

Chitin recognition in rice and legumes,fungal pathogens induce plant defense reactions in rice, while lipo-chitin oligosaccharides (dp=4–5) induce the development of a new plant organ, the nodule, in legumes during infection by rhizobia. The former situation is pathogenic and the latter situation beneficial to the plant. However, these t
