The pattern of arsenate, but not arsenite, resistance was achieved Frankia in the nitrogen-fixing plant symbiont Sinorhizobium meliloti. In the absence of genetic tools to assess gene function in Frankia, H: Novel pathway for arsenic detoxification in the legume symbiont Sinorhizobium meliloti. In addition, studies using functional genomic tools have established the Third, the Sinorhizobium meliloti operon includes a gene coding for As(V) is known to be a structural analogue of phosphate, interfering Novel pathway for arsenic detoxification in the legume symbiont Sinorhizobium meliloti.

Novel efflux proteins ArsJ and AqpS confer resistance to arsenate even though Arsenic detoxification pathways are found in nearly every present-day Studies addressing arsenosugar and arsenolipd toxicity, though largely AqpS, in the ars operon of Sinorhizobium meliloti that mediates As(III) efflux (Yang et al., 2005). Reporter-gene studies showed that the arsenic operon of transposon origin The structure of the At.
