Outline of Final Research Achievements

Cenococcum geophilum (Cg) is a type of rhizobia and sclerotium grains are resting bodies of Cg found over the world. Sclerotium grains contain a remarkable amount of 4,9-dihydroxyperylene-3,10-quinone (DHPQ), however, its role is still unclear. In this study, I examined the role of DHPQ in sclerotium grains such as "material to keep its structure", "material for electron transfer" and "material for antibiotic property". From the results, DHPQ should play important role for media of electron transfer, defense from radical stresses from outside, or both.
