Twenty-nine strains were isolated from two samples of the permafrost active layer Spitsbergen archipelago. The estimated number bacteria ranged 4.0⋅104 to 1.7⋅107 CFU∙g-1. As a result sequencing 16S rRNA (rrs) genes, isolates assigned 13 genera belonging phyla Actinobacteria, Proteobacteria (classes α, β, and γ), Bacteroidetes, Firmicutes. Six belonged rhizobial genus Mesorhizobium (order Rhizo...

Leguminous plants and bacteria from the family Rhizobiaceae form a symbiotic relationship, which culminates in novel plant structures called root nodules. The indeterminate symbiosis that forms between Sinorhizobium meliloti and alfalfa requires biosynthesis of Nod factor, a beta-1,4-linked lipochitooligosaccharide that contains an essential 6-O-sulfate modification. S. meliloti also produces s...
