Ensifer meliloti strains isolated from the field are more mucoid than lab strains and do not differ from the lab strains in terms of nodule development. However, lab strains are not real life bacteria and to grow more food in the future in the field, we need to look beyond the lab.
Although our experiments show little effect on nodule development under lab conditions, native E. meliloti strains are often mucoid in the field suggesting that they are better adapted to soil environments. Upon legume inoculation, the presence of excess polysaccharide may increase legume productivity in the field by desiccation protection, by enhancing plant tolerance to stress, and by promoting bacteria consortium development.
Our goal is to improve plant growth and yield by employing plant growth-promoting bacteria instead of synthetic chemicals. The use of the latter has significantly damaged soils, which negatively affects plant growth.Dr. Ann M Hirsch, PhD
