''Phytophthora cambivora'' is a plant pathogen that causes Ink disease in European Chestnut trees (''Castanea sativa''). Ink disease, also caused by ''Phytophthora cinnamomi'', is thought to have been present in Europe since the 18th century and causes chestnut trees to wilt and die, major epidemics occurred during the 19th and 20th centuries. ''P. cinnamomi'' and ''P. cambivora'' are now present throughout Europe and since the 1990s Ink disease has resurged, often causing high mortality of trees, particularly in Portugal, Italy and France.〔 〕 It has also been isolated from a number of different species since the 1990s including: *Golden chinquapin trees, (''Chrysolepis chrysophylla'') in Oregon, USA. *''Rhododendron'' and ''Pieris'' species in North Carolina, USA. *Noble Fir trees (''Abies procera'') in Norway. *Beech trees (''Fagus sylvatica'') in Italy and Germany. Some species of mycorrhiza (including ''Amanita muscaria'', ''Suillellus luridus'' and ''Hebeloma radicosum'') may provide protection from ''P. cambivora'' in European Chestnuts. == See also == * Forest pathology * Wilt disease 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phytophthora cambivora」の詳細全文を読む スポンサード リンク
