Title

Advances in Frankia genome studies and molecular aspects of tolerance to environmental stresses

Abstract

Actinobacteria from the genus Frankia are Gram+, aerobic, heterotrophic and filamentous bacteria found living independently in soil or as facultative symbionts that form N2-fixing root nodules on diverse and globally distributed angiosperms called actinorhizal species. This symbiotic association has important ecological and economic roles such as soil stabilization, land reclamation, crop protection and timber and fuel wood production. Some Frankia strains are resistant to abiotic stresses including salinity, heavy metal, pH, and temperature and have developed complexed mechanisms to adapt to these conditions. Under environmentally stressed conditions, actinorhizal plants that had associations with adapted Frankia strains show improved plant performance. Recent “Omics” studies including genomic, transcriptomic and proteomic developed on Frankia have provided different clues for a better understanding of these adaptation mechanisms. In this chapter, we review recent advances in Frankia genome studies and in molecular aspects of Frankia tolerance to environmental stresses.
