Genome sequence of the Lotus spp. microsymbiont Mesorhizobium loti strain NZP2037

Abstract

Mesorhizobium loti strain NZP2037 was isolated in 1961 in Palmerston North, New Zealand from a Lotus divaricatus root nodule. Compared to most other M. loti strains, it has a broad host range and is one of very few M. loti strains able to form effective nodules on the agriculturally important legume Lotus pedunculatus. NZP2037 is an aerobic, Gram negative, non-spore-forming rod. This report reveals that the genome of M. loti strain NZP2037 does not harbor any plasmids and contains a single scaffold of size 7,462,792 bp which encodes 7,318 protein-coding genes and 70 RNA-only encoding genes. This rhizobial genome is one of 100 sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) project.
