“Background Rhizobia are nitrogen-fixing soil bacteria that show intracellular symbiosis with their

host legume. This symbiotic interaction has become a model system to identify and characterize the attractive mechanism employed by invasive bacteria during chronic host interactions [1]. This symbiosis begins with the secretion of flavonoids by the legume. Subsequently, nod genes of rhizobia are activated, and Nod factors (i.e. lipopolysaccharides; LPS) are secreted by rhizobia as signals [2]. After signal exchange between host and symbiont, rhizobia infect the host legume, escaping the vegetative defense responses. The host then produces nodules to maintain symbionts and endocytically incorporates rhizobia into the nodules [3]. In a legume nodule, the host provides C4 dicarboxylates to symbiotic rhizobia as the carbon source; rhizobia fix atmospheric nitrogen and provide ammonia to the host as a nitrogen source in return [4]. Thus, the host plants are able to overcome their nitrogen deficiency. Lotus japonicus and Mesorhizobium loti are model organisms of legume-rhizobia symbiosis. The entire genome structures of L. japonicus MG-20 and M. loti Protein kinase N1 MAFF303099 have been reported

previously [5, 6], and the database is maintained by the Kazusa DNA Research Institute (Rhizobase; http://​genome.​microbedb.​jp/​rhizobase). Transcriptome analysis of M. loti by DNA microarray revealed that most of the transposase genes and nif, fix, fdx, and rpoN on the symbiosis island were highly upregulated under the symbiotic condition, while genes for cell wall synthesis, cell division, DNA replication, and flagella formation were strongly repressed under the symbiotic condition [7]. However, less information is available about M. loti than about other genera of rhizobia, such as www.selleckchem.com/products/ch5424802.html Sinorhizobium meliloti, Rhizobium leguminosarum, and Bradyrhizobium japonicum. In addition to transcriptome analysis, proteome analysis has recently attracted much attention.
