Lipogenesis and redox balance in nitrogen-fixing pea bacteroids by Ratcliffe, R, Terpolilli, J, Masakapalli, S, Karunakaran, R, Webb, I, Green, R, Kruger, N, Poole, P, Watmough, N

“…Within legume root nodules, rhizobia differentiate into bacteroids that oxidise host-derived dicarboxylic acids, which is assumed to occur via the TCA-cycle to generate NAD(P)H for reduction of N2. …”

Transcriptomic analysis of Rhizobium leguminosarum bacteroids in determinate and indeterminate nodules by Green, RT, East, A, Karunakaran, R, Downie, JA, Poole, PS

“…In indeterminate nodules, rhizobia terminally differentiate into bacteroids with endoreduplicated genomes, whereas bacteroids from determinate nodules are less differentiated and can regrow. …”

Rhizobium sp. strain NGR234 and R. fredii USDA257 share exceptionally broad, nested host ranges by Pueppke, S.G., Broughton, W.J.

“…(Phaseoleae), both bacteria formed more effective symbioses than rhizobia of the "cowpea" (V. unguiculata) miscellany. …”

First-principles study of nitric oxide reduction reactions for ammonia electrochemical synthesis by Foo, Yong Chean

“…As one of the most important gases used in our human history and the ecology of our planet, ammonia has played a key role as the chemical feedstock in the synthesis of reactive nitrogen compounds between nitrogen-fixing rhizobia and plants. With more upcoming clean renewable energy technology aiming to make use of its high volumetric energy density for its potential for fuel and cheap grid-level scale energy storage solution, demand for NH3 has been at its highest yet. …”

Characterising root attachment in Rhizobium-legume symbioses by Parsons, J

“…This is crucial for nitrogen-fixing symbiosis development and underpins many plant growth-promoting relationships. Rhizobia use a variety of factors for primary attachment including pH-dependent adhesins (such as glucomannan and the hypothesised rhicadhesin), surface proteins and extracellular polymeric substances. …”

The genetic control of root attachment and colonisation in Rhizobium leguminosarum by Cocker, C

“…Of up to 70 million tonnes of nitrogen that are fixed into agricultural systems by biological nitrogen fixation each year, 40 million are fixed by rhizobia in symbiosis with legumes. Attachment to and colonisation of host plant roots are essential precursors to formation of a successful nitrogen-fixing symbiosis between <em>Rhizobium</em> strains and their host legumes but are less well-characterized than other stages of symbiosis formation. …”

Metabolic control of nitrogen fixation in rhizobium-legume symbioses by Schulte, CCM, Borah, K, Wheatley, RM, Terpolilli, JJ, Saalbach, G, Crang, N, de Groot, DH, Ratcliffe, RG, Kruger, NJ, Papachristodoulou, A, Poole, PS

“…Rhizobia induce nodule formation on legume roots and differentiate into bacteroids, which catabolize plant-derived dicarboxylates to reduce atmospheric N2 into ammonia. …”
