The Symbiotic Plasmid of Rhizobium Etli
Bacteria of the Rhizobiaceae family are capable of interacting with the roots of higher plants, this family includes several genera of pathogens, such as Agrobacterium spp. as well as others that can establish a nitrogen-fixing symbiosis with legumes, i.e. Rhizobium, Sinorhizobium,Bradyrhizobium, etc. Rhizobiaceae were originally classified mainly on the basis of phenotypic features such as growth properties, colony morphology and host range (Martínez et al. 1990). Genetic information in these bacteria is usually distributed among various replicons including the chromosome and several large plasmids.
