Abstract :研究成果の概要(和文):日本には2種のブドウさび病菌が分布し,ヤマブドウで2種が重複感染していた.分子系統解析の結果は熱帯アジアのブドウさび病菌が新分類群であることと地理的分布の異なる3菌群で構成されていることを示した.アメリカの2種のブドウさび病菌はメキシコ湾岸に沿った狭い地域を境に分布を違えていた.分子系統解析の結 果,これら2種は近縁でツタ,アワブキおよびミヤマハハソに寄生するサビキンと同一のグループに含まれることが明らかとなった.いっぽう,東アジアおよび東南アジアのブドウさび病菌は近縁であるが,アメリカのブドウさび病菌とは系統的に遠く,東アジアに分布するツタさび病菌と直近の祖先を共有することを推定できた. 研究成果の概要(英文):Two grapevine leaf rust fungi were widely distributed in Japan. The two fungi were found to occur simultaneously on Vitis coignetiae innature. 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.
