In vivo CO2 fixation activity and in vitro phosphoenolpyruvate carboxylase activity were demonstrated in effective and ineffective nodules of alfalfa (Medicago sativa L.) and in the nodules of four ...

Low nitrogen availability is the number one limitation to plant growth in most ecosystems. Plants in the bean family and other closely related families evolved a symbiotic relationship with bacteria ...

Nitrogen is essential for all plants and animals, but despite being surrounded by it—the element constitutes 79% of air on earth—only a few bacteria can absorb it directly from the environment. All ...

Beans plants evolved nitrogen-fixing tricks - an ancient secret that could help crops grow with less fertilizer and transform ...

My laboratory research has focused on the symbiotic association of nitrogen-fixing Rhizobium meliloti with its host plant alfalfa. The specific interaction of the bacteria with alfalfa root hairs ...

Symbiotic nitrogen fixation (SNF) by intracellular rhizobia within legume root nodules requires the exchange of nutrients between host plant cells and their resident bacteria. Little is known at the ...

Scientists discover the genetics inside legumes that control the production of an oxygen-carrying molecule, crucial to the plant's close relationships with nitrogen-fixing bacteria. The finding offers ...

LSH1/LSH2 are required to make nodules an infectable and habitable organ for rhizobial bacteria: Confocal image of WT and lsh1/lsh2 roots 24 and 72 hpi with S. meliloti (n > 30 per genotype and time ...
