| Research Abstract |
Some symbiotic mutants of Lotus japonicus, specific for arbuscular mycorrhiza (AM), were analyzed by the linkage mapping and the phenotypic characterization . As the results of phenotypic characterization of back-crossed F3 generation, AM formation was inhibited around entry points in ME778 and ME966. On the other hand, trunk hyphae of arbuscule were formed in roots of ME2329, but fine branches were abnormal. By the linkage mapping, mutation point of ME2329 was mapped on southern part of chromosome 4 and those of ME778 and ME966 weremapped on chromosome 2.
