The present invention relates to a bacterial composition, comprising: at least one genetically modified bacterial strain, which fixes atmospheric nitrogen in an agricultural system, the bacterial strain comprising a modification of one or more genes selected from the group consisting of bcs11, bcslll, yjbE, fhaB, pehA, glgA, otsB, treZ and cysZ. The present invention further relates to a bacterial composition and a method for increasing the colonization, on a plant, of a bacterial strain promoting plant growth, the plant growth-promoting bacterial strain having been remodeled to increase the colonization of said plant. In another aspect, the present invention relates to methods of increasing nitrogen or nitrogen fixation available to a plant. |
