Researchers demonstrate that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. Researchers ...

Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors ...

Plants have developed mechanisms to fight pathogenic bacterial infection, but in the beneficial symbiotic association, entry of the nitrogen-fixing bacteria is accepted. The legume-symbiotic rhizobia ...

Journal of Experimental Botany, Vol. 69, No. 8 (2018), pp. 2117-2130 (14 pages) Leguminous plant roots can form a symbiosis with soil-dwelling nitrogen-fixing rhizobia, leading to the formation of a ...

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 ...

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 ...

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 ...

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 ...

PLANTS NEED nitrogen to make proteins and DNA. But though this element is abundant in the air, they have failed to evolve the biochemical apparatus needed to break up nitrogen molecules and combine ...
