The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and ...

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 ...

Most scientific research on the root-soil interactions of legumes focuses on rhizobia and nitrogen-fixing root nodules. However, many forms of non-rhizobia bacteria are also detected in these nodules.

The availability of nitrogen is important for plant growth and stress resistance. Legumes are able to form beneficial symbiotic associations with nitrogen-fixing rhizobial bacteria that provide ...

The objectives of this study were (a): to define the effects of light, dark, and temperature on nodule activity (acetylene reduction), and (b) to establish the contributions of reserve carbohydrate ...

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 ...

St. Paul, Minn. (July 2017)--For many years, it was believed that the only nitrogen-fixing organisms of legume nodules were rhizobia. However, there is a strikingly diverse population of non-rhizobia ...
