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 ...

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 ...

In a study published in Science, researchers have resolved, for the first time, the high-resolution crystal structure of the complex formed between the NodD protein of pea rhizobia and a flavonoid ...

Legumes thrive in low-nitrogen environments by partnering with rhizobia, soil bacteria that convert atmospheric nitrogen into ammonium, a usable form for the plants. These beneficial bacteria are ...

To make protein, soybean plants need a lot of nitrogen. Beneficial bacteria in root nodules typically assist. A new study shows it's possible to increase the number of soybean root nodules--and the ...

WHEN a legume root is infected by the nodule organism, the formation of the young nodule is brought about by the multiplication and growth in size of the root-cells, principally in the cortex. In ...

Researchers at University of Tsukuba have uncovered a master transcriptional regulator that controls rhizobial symbiosis ...

WEST LAFAYETTE, Ind. – Plant breeders could theoretically increase soybean crop yields if they could control the number of nodules on plant roots since they are responsible for fixing atmospheric ...

Peas and other legumes develop spherical or cylindrical structures -- called nodules -- in their roots to establish a mutually beneficial relationship with bacteria that convert atmospheric nitrogen ...

The formation of first nodules inhibits subsequent nodulation in younger regions of alfalfa (Medicago sativa L.) roots by a feedback regulatory mechanism that controls nodule number systemically (G ...

Cambridge scientists have identified two crucial genetic factors needed to produce specialised root organs that can accommodate nitrogen-fixing bacteria in legumes such as peas and beans. In a ...
