BIOTECHNOLOGY OF RHIZOSPHERE BACTERIA

Ramón Peñalver Navarro, Center for Plant Protection and Biotechnology, IVIA, Valencia

 

The IVIA Rhizosphere Bacteria Biotechnology team has as its global objective the selection of beneficial bacteria that serve as the basis for the development of new bioproducts for the agri-food and citrus industry. To do this, it develops two lines of research; (i) A line of basic research aimed at determining the genetic and genomic bases of the beneficial Rhizobium rhizogenes (formerly Agrobacterium radiobacter) K84-plant interaction, as a model of bacteria highly adapted to life in the rhizosphere. (ii) and another line of research aimed at the biotechnological use of citrus microbiomes through metagenomics and culturomics studies. More specifically, this line aims to reveal, analyze and exploit the citrus microbiota.
