| local adaptation of frankia to different discaria (rhamnaceae) host species growing in patagonia. | frankia bcu110601 (da) and frankia bcu110345 (dc) were isolated from root nodules of discaria articulata and discaria chacaye, respectively; frankia bcu110501 (dt) was previously isolated from discaria trinervis. the strains were identical at the 16s sequence and after analysis of rflp of 16s and 23s rdna intergenic region. diversity was revealed at the molecular level after fingerprint analysis by box-polymerase chain reaction. the strains were infective and effective on the original host plant ... | 2006 | 17106801 |
