Growth of Rhizobia in Protein Hydrolysates
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Mikrobiologie der Landwirtschaft, der Technologie und des Umweltschutzes, 1980Sixteen nitrogen-rich agricultural and industrial wastes and by-products, such as vegetable waste, lasora (Cordia myxa L.), meat waste, water-hyacinth (Eichhornia crassipes), and pea (Pisum sativum L.) husks were partially hydrolysed to amino acids with the help of acetic acid of 1, 5, 10, 15, and 20% concentration.

Vertical Movement of Rhizobia in Soil
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1974Summary The vertical migration of Rhizobium trifolii cells, due to the leaking-through of water, was examined in a model experiment. The cell migration increased with the soil particle sizes and with the amount of water used. As reported earlier ( Hamdi 1971), the data on the movement of rhizobia in soil are very limited. Few papers have dealt with

Plasmid transfer systems in the rhizobia
Canadian Journal of Microbiology, 2009Rhizobia are agriculturally important bacteria that can form nitrogen-fixing nodules on the roots of leguminous plants. Agricultural application of rhizobial inoculants can play an important role in increasing leguminous crop yields. In temperate rhizobia, genes involved in nodulation and nitrogen fixation are usually located on one or more large ...

Host-Plant Invasion by Rhizobia
2000Colonization of legume roots by compatible soil bacteria of the genera Azorhizobium, Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium (collectively known as rhizobia) leads to the formation of specialized nitrogen-fixing organs called nodules. Signals produced by both partners control specificity. Flavonoids found in root exudates trigger the

Symbiosis for rhizobia is not an easy ride
Nature MicrobiologyPhilip Poole narrates his career story and his motivations for studying rhizobia, the agriculturally important bacterial plant symbiont responsible for fixing nitrogen.

Mutualism in Metapopulations of Legumes and Rhizobia
The American Naturalist, 1999Coevolution in mutualisms may result in a stable mosaic pattern of spatial differentiation, with regions occupied by different coadapted pairs of mutualists each being resistant to invasion by organisms with alternative phenotypes. The evolution of geographic mosaic patterns was analyzed for symbioses of legume plants and root-nodule bacteria (rhizobia)
