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 ...

• Symbiotic nitrogen (N₂) fixation plays a vital role in sustainable agriculture. Efficient N₂ fixation requires various materials, including phosphate (Pi); however, the molecular mechanism ...

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 ...

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 ...

The role of sucrose synthase (SS) in the fixation of N was examined in the rug4 mutant of pea (Pisum sativum L.) plants in which SS activity was severely reduced. When dependent on nodules for their N ...

Researchers from several institutions, including the Florida Museum of Natural History, have recently determined that the chemical receptors plants use to recognize nitrogen-fixing bacteria in the ...

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 ...

Clover plants grown in Mars-like soils experience significantly more growth when inoculated with symbiotic nitrogen-fixing bacteria than when left uninoculated. Franklin Harris of Colorado State ...

Henan University is one of China’s rapidly rising research institutions. Based in the city of Kaifeng, in China’s central north, it ranked 37 th in China’s top 50 rising institutions for research ...
