Resumen del proyecto:

The main objectives are defined as follows :

• To carry out quantitative analyses of the Sinorhizobium fredii and Bradyrhizobium japonicum populations in soils of four different Chinese soybean cropping areas. It will be determined the density (bacteria / gram of soil) of indigenous populations of S. fredii and B. japonicum and a collection of these bacterial strains will be made.
• To determine the importance of pH as a key factor in determining the final outcome of the competition for soybean nodulation between S. fredii and B. japonicum.
• To analyze the symbiotic capacity of different Western and Asiatic soybean cultivars in order to determine the best pairs soybean cultivar-inoculant strain.
• To isolate S. fredii and B. japonicum strains that are highly effective and / or competitive as soybean inoculants.
• To investigate the symbiotic properties of Sinorhizobium meliloti strain 042B. This bacterial strain has recently been isolated in China and it is able to nodulate effectively on both alfalfa and soybean plants.
