Lotus japonicus is a wild legume that belongs to family Fabaceae. Members of this family are very diverse comprising of about 20,000 species. They are of significant agricultural and biological importance as many of the legume species are rich sources of protein and oil and can also fix atmospheric nitrogen.

L. japonicus has become a model plant for genome studies in legumes, particularly in reference to rhizobial and arbuscular mycorrhizal symbiosis. Small genome size of about 470 Mb, diploid genome with 6 haploid chromosomes and a short life cycle of about 2 to 3 months makes it a convenient plant to study. Kazusa DNA Research Institute in Japan, is presently the only institute involved in sequencing its genome. They initially sequenced the genome of Mesorhizobium loti, an endosymbiont associated with L. japonicus and then started sequencing the host genome.
