This is Doris Zuñiga, again.

Several researchers in Latin America have demonstrated the importance of the growth promoting plant bacteria among which are the nitrogen-fixing in various crops, the soybean crop is very important in Brasil and Argentina and pastures in Uruguay (Biofertilizantes en Iberoamérica: Una visión técnica, científica y empresarial. 2007. Edited by M.L. Izaguirre-Mayoral, C. Labandera and J. Sanjuan. 98 pages. http://www.biofag.org.ar/actividades/publicaciones/Libro-Biofag2007.pdf [2 MB]).

The genomics of these rhizobacteria allows their identification and the phylogenetic relationships among them, as well as knowing the different key genes in the processes of nitrogen fixation, solubilization of phosphate, production of hormones, genes for tolerance in conditions of stress, among others. All this is a great potential for the application of these bacteria in plants for their improvement.

Now, the inoculation of identified and selected strains in the cultivation of soya has a very large economic impact (millions of dollars per year) which means big savings for the farmer. But this is accompanied by a good implementation of legislative mechanisms to ensure good quality inoculants.

The economic impact within 5 years will be seen in other important crops (potatoes, beans, corn, among others) as there will be a greater bank of characterized strains, specific for each crop and each environment. However, it requires a larger demonstrative work with farmers and their relationship with the companies and universities.
