International research on interactions between plants and microorganisms FAO

The IRNAS and the University of Salamanca working on the study of a type of legume endangered Brazil extinction in collaboration with Scottish scientists

Institute Natural Resources and Biotechnology (IRNAS) of Salamanca and the University of Salamanca have started a research on the interaction between leguminous plants and microorganisms in collaboration with the prestigious Scottish Crop Research Institute (SCRI) in Dundee, Scotland (United Kingdom). The aim is to study how a type of bacteria in the soil contributes to nitrogen fixation, an essential nutrient in plants.

Advances in this field are very important for agriculture, contributing to the elimination of dependence on chemical fertilizers to improve plant nutrition by microorganisms.

Euan James, a researcher at the Scottish Crop Research Institute , visited the IRNAS to advance this project together and provide a scientific seminar to Salamanca about his research. "We work in the field of interactions between plants and microorganisms, particularly in legumes, which are capable of fixing atmospheric nitrogen in the air by interaction with a soil bacteria that enter the roots forming nodules and this is very important for agriculture in the future because it has environmental implications by reducing the rate of nitrogen fertilizer necessary to add the soil, ie, contributing to the independence of these legumes in this sense, "said the expert told DiCYT ( www.dicyt.com ).

The organisms that interact with the plant are bacteria of the genus Rhizobium or rhizobia. But the great contribution of the research group of Euan James has been to locate "a new type of bacteria that are able to establish this interaction. If the rhizobia belong to the alpha-proteobacteria class, the Scottish researchers have discovered a beta proteobacteria, other than the classical rhizobia, which are "Very adaptable to different environmental conditions" and are "able to carry out nitrogen fixation perfectly well", according to experts have found tropical legumes.

Following these advances, scientists from IRNAS Salamanca and the University of Salamanca, which also include knowledge in this area have begun a collaboration with the Scottish Crop Research Institute . In particular, the scientist at the IRNAS Alvaro Peix Geldart explained the initiative. "We are collaborating in the study of the infection process of some tropical legumes are in danger of extinction Brazil. It's about seeing their interactions and find out how microorganisms these legumes form nodules "he says.
