Phytophthora ramorum, causal agent of sudden oak death, is an emerging plant pathogen first observed in North America associated with mortality of tanoak (Lithocarpus densiflorus) and coast live oak (Quercus agrifolia) in coastal forests of California during the mid-1990s. The pathogen is now known to occur in North America and Europe and have a host range of over 40 plant genera. Sudden oak death has become an example of unintended linkages between the horticultural industry and potential impacts on forest ecosystems. This paper examines the biology and ecology of P. ramorum in California and Oregon forests as well discussing research on the pathogen in a broader management context.
栎树猝死病的病原菌——栎树疫霉,是一种新出现的植物病原体,20世纪90年代中期首次在北美被发现,与加利福尼亚沿海森林中的加州石栎(Lithocarpus densiflorus)和海岸活栎(Quercus agrifolia)死亡有关。现在已知该病原体在北美和欧洲均有出现,寄主范围超过40个植物属。栎树猝死病已成为园艺产业与对森林生态系统潜在影响之间意外联系的一个例子。本文研究了栎树疫霉在加利福尼亚和俄勒冈森林中的生物学和生态学,并在更广泛的管理背景下讨论了对该病原体的研究。
