| genetic diversity of root-nodulating bacteria isolated from pea (pisum sativum) in subtropical regions of china. | diversity of 42 isolates from effective nodules of pisum sativum in different geographical regions of china were studied using 16s rrna gene rflp patterns, 16s rrna sequencing, 16s-23s rrna intergenic spacer (igs) region rflp patterns and g-c rich random amplified polymorphic dna (rapd). the isolates were distributed in two groups on the basis of their 16s rrna gene rflp patterns. the 16s rrna gene sequences of strains from 16s rrna gene rflp patterns group i were very closely related (identitie ... | 2008 | 18726533 |
