Outline of Final Research Achievements

Two grapevine leaf rust fungi were widely distributed in Japan. The two fungi were found to occur simultaneously on Vitis coignetiae in nature. Molecular systematic studies showed that tropical Asian grapevine leaf rust was incited by a new rust taxon, which was consist of three geographically different populations.
Two American grapevine leaf rust fungi were found to be separated in their geographic distribution roughly by narrow areas along the coast of the Gulf of Mexico. Molecular systematic studies indicated that the two species were closely related and grouped with rust fungi parasitic on Parthenocissus tricuspidata, Meliosma myriantha and M. tenuis. However, they were distantly related to East Asian grapevine leaf rust fungi. It was assumed that the American grapevine leaf rust fungi shared the most recent ancestor with the Parthenocissus leaf rust fungus.
