New approaches are required to meet the demand for an increased global food supply that do not harm the environment and are produced in a sustainable fashion. This study examine how the microorganisms associated with plants, the plant microbiome can be engineered to improve crop quality and yield using synthetic biology approaches. The overall aim of the project is to contribute to an alternative and more sustainable future for agriculture.
The methodology used in this study couples in silico genomic comparison tools with in vivo bacterial genomes manipulation, the latter have been carried out applying new gene transfer methods and the CRISPR-Cas9 genome editing approach. We are employing these techniques to modify the genomes of plant growth-promoting rhizobaceria and also the metagenome of the rhizosphere community in order to obtain a synthetic bacterial consortium with improved capabilities of promotion of disease resistance or resource utilization in the partner crop. As a result, we also hope to gain a broader understanding of the interactions occurring between bacteria and plants in this complex environment.
