Plants respond similarly to signals from friends, enemies

...the NC State researchers discovered that the model legume Lotus japonicus responded similarly to signals from both rhizobia, the friends that fix nitrogen for the plant, and root-knot nematodes, the parasitic foes that want to harm the plant. Signals from both outsiders induce rapid changes in distribution ...

Plant hemoglobins: Oxygen handlers critical for nitrogen fixation

...n of symbiotic hemoglobins in nodules of the model legume Lotus japonicus, enabling researchers to assess for the first time the role and importance of these proteins in plants. The results of the study indicate that symbiotic hemoglobins are important for oxygen transport and energy metabolism in plant roo...

Plants, too, have ways to manage freeloaders

...dulation. This could explain why soybean and other legume crops in fields inoculated with the supposedly most efficient strain of nitrogen-fixing bacteria do not always take up that strain - an expensive problem for farmers. "The most effective strain is not always best at competing for nodules," Simms sai...

New maps reveal true extent of human footprint on Earth

...ve increasingly cleared forests to grow soybean, a legume that has never been a traditional crop of Latin America. Scientists say the surge in soybean production there has a lot to do with the booming demand for soy all the way at the other end of the world - in China. Meanwhile, Monfreda notes, long-time s...

Legume compounds may help cancer treatment

...have identified several compounds derived from the legume interaction with rhizobium bacteria that show strong anti-angiogenic activity. "They are promising therapeutic molecules which clearly warrant further investigation," Professor Parish said. CILR Director Professor Peter Gresshoff said the current r...

Pesticides choke pathway for nature to produce nitrogen for crops
