Research Abstract

温帯や熱帯の植物と同様に,極地に自生するコケや顕花植物にも植物病原菌が広く感染し,一部の地域では枯死などの被害が発生している。これら極地の植物病原菌の多くは,これまでに報告の無い種が多く,それらの生態についてはほとんどわかっていない。一方,近年の気候変動により植物病原菌と宿主植物とのバランスが崩ずれ,これまでにない植物病害が世界的に頻発している。とくに極地は,温暖化の進行が他の地域よりも急速で,植物病原菌と宿主植物とのバランス崩壊がより速く進んでいる可能性がある。この研究の目的は,極地に発生する植物病原菌を対象として,それらの種を特定するとともに,植物病原菌と宿主植物とのバランスの変化の実態を明らかにすることである。
