Abstract:
:The symbiotic plasmid (pSym) DNA present in bacteroids of strain RCR1001 of Rhizobium leguminosarum biovar viceae has been compared qualitatively and quantitatively with that present in free living bacteria by hybridization experiments with appropriate probes. A decrease in the relative amount of pSym DNA was observed in bacteroids as compared to bacteria. No rearrangements of the symbiotically expressed pSym borne genes were detected in bacteroids.

杂志文章abstract::The presence of diatoms in victim's internal organs has been regarded as a gold biological evidence of drowning. The idea becomes true at the advent of DNA metabarcoding. Unfortunately, the DNA barcode of diatoms are far from being applicable due to neither consensus on the barcode and nor reliable reference library.I...
