Root secretion and plant immunity are key factors in controlling the assembly of root-associated microbiotas of which rhizobia are key members Rhizobia exist in soil and compete with the general ...

Tsukuba, Japan - Legumes such as peas and beans form intimate and mutually beneficial partnerships (symbioses) with nitrogen-fixing bacteria, rhizobia. The plant benefits from an enhanced supply of ...

Scientists have elucidated how NodD recognizes flavonoids by resolving, for the first time, the high-resolution crystal structure of the complex formed between the NodD protein of pea rhizobia and 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 ...

1. Ecologists have become increasingly aware that silicon uptake by plants, especially the Poaceae, can have beneficial effects on both plant growth and herbivore defence. The effects of silicon on ...

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 ...

All aerobic biological systems, including N2-fixing root nodules, are subject to O2 toxicity that results from the formation of reactive intermediates such as H2O2 and free radicals of O2. H2O2 may be ...

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 ...

Soybeans and other legumes interact with nitrogen-fixing soil bacteria called rhizobia that are able to convert nitrogen in the air into a form the plant can use to grow and reproduce. Corn and other ...
