| Outline of Final Research Achievements |
The complete nucleotide sequence of the genome of a Lotus japonicus endophyte was determined. For sequencing, a cosmid genomic library was constructed, and the library is available as a tool for post genomics. The 2974 clones, all of which have been mapped on the genome, contain inserts of approximately 28 kb. The genome of the endophyte consists of a chromosome (4779007 bp) and two plasmids (2509446 bp and 614482 bp). The genome comprises 7703 protein-encoding genes, three copies of rRNA gene clusters and 54 tRNA genes. Fourty-two percent of the protein-encoding sequences shown sequence similarity to genes of known function were classified into SEED subsystems. Compared with other Rhizobium species, no gene for either nitrogen fixation nor nodulation was notable characteristics of this endophyte. Three gene clusters related to the protein secretion classified into T3SS or T4SS were identified. These may be involved in the plant-microbe interactions.
