Complete genome sequence of Sinorhizobium meliloti strain AK21, a salt-tolerant isolate from the aral sea region

Abstract

We report here the complete genome sequence of the salt-tolerant Sinorhizobium meliloti strain AK21, isolated from nodules of Medicago sativa L. subsp. ambigua inhabiting the northern Aral Sea Region. This genome (7.36 Mb) consists of a chromosome and four accessory plasmids, two of which are the symbiotic megaplasmids pSymA and pSymB.Strain SmeAK21 was provided by Marina Roumiantseva and Boris Simarov to the partners of the International Cooperation-Cooperation with the Countries of Central Europe and with the New Independent States of the Former Soviet Union (INCO-COPERNICUS) program (grant ICA2-CT-2001-10001), and it is available at the All-Russia Research Institute for Agricultural Microbiology (ARRIAM; strain collection number RCAM05222). This work was funded by European Regional Development Fund (ERDF)-cofinanced grants from the Spanish Ministerio de Ciencia, Innovación y Universidades (grant CSD2009-00006 to N.T. and grants AGL2009-07925 and BFU2017-82645-P to J.I.J.-Z.)
