Salicylic acid biosynthetic genes expressed in Rhizobium: Rhizobium strains harboring salicylic acid gene via horizontal gene transfer

It is evident that it is possible to select rhizobial strains harboring recombinant genomes that were efficient in secrete IAA as a plant hormone, as well as, salicylic acid as a inhibitor agent against pathogenic microorganisms. Bacteriocins produced from these recombinant strains had a good performance to inhibit the growth of Agr1513 as an soil pathogen. In addition, rhizobial recombinants appeared symbiotic effectiveness leading to increase grain yield, as well as, improving biochemical traits such as grain protein contents and leaves chlorophyll concentration.
