Plasmids with a chromosome-like role in rhizobia.

Replicon architecture in bacteria is commonly comprised of one indispensable chromosome and several dispensable plasmids. This view has been enriched by the discovery of additional chromosomes, identified mainly by localization of rRNA and/or tRNA genes, and also by experimental demonstration of their requirement for cell growth. The genome of Rhizobium etli CFN42 is constituted by one chromoso...

Plasmid replicons of Rhizobium.

Rhizobium spp. are found in soil. They are both free-living and found symbiotically associated with the nodules of leguminous plants. Traditionally, studies have focused on the association of these organisms with plants in nitrogen-fixing nodules, since this is regarded as the most important role of these bacteria in the environment. Rhizobium sp. are known to possess several replicons. Some, l...

Construction of physical map and mapping of chromosomal virulence genes of the biovar 3 Agrobacterium (Rhizobium vitis) strain K-Ag-1.

Most plant pathogenic Agrobacterium strains have been classified into three biovars, "biovar 1 (A. tumefaciens; Rhizobium radiobacter), biovar 2 (A. rhizogenes; R. rhizogenes) and biovar 3 (A. vitis; R. vitis)". The bacteria possess diverse types of genomic organization depending on the biovar. Previous genomic physical maps indicated difference in location of rDNA and chromosomally-coded virul...
