摘要
Colletotrichum coccodes 是马铃薯的重要病原体。最近，与它关系密切的 C. nigrum 被报道为茄科作物的重要病原体，但不是马铃薯的病原体。本研究证实，C. coccodes 是感染澳大利亚和美国马铃薯叶片和块茎组织的最普遍的 Colletotrichum 物种。此外，之前被鉴定为 C. coccodes 的来自美国的三个分离株被重新鉴定为 C. nigrum。基因位点 TUB2、ACT、GAPDH、CHS-1 或 HIS3 都适用于区分黑茎马铃薯和椰子马铃薯。澳大利亚和美国的 C. coccodes 和 C. nigrum 块茎和叶片分离物对马铃薯分离叶片的致病性相似。这是首次报道 C. nigrum 是马铃薯的病原体。此外，最近描述的 C. dianense 被发现是 C. nigrum 的异名。
Potato leaf infection caused by Colletotrichum coccodes and C. nigrum
Colletotrichum coccodes is an important pathogen of potatoes. Recently, the closely related C. nigrum has been reported as an important pathogen of solanaceous crops but not as a pathogen of potato. This study confirms C. coccodes as the most prevalent Colletotrichum species infecting foliar and tuber tissue of potatoes in Australia and the USA. In addition, three isolates from the USA, previously identified as C. coccodes, were re-identified as C. nigrum. The gene loci TUB2, ACT, GAPDH, CHS-1 or HIS3 were all suitable for differentiating C. nigrum from C. coccodes. Australian and USA tuber and foliar isolates of C. coccodes and C. nigrum had similar pathogenicity on detached potato leaves. This is the first report of C. nigrum as a pathogen of potato. Moreover, the recently described C. dianense was revealed to be a synonym of C. nigrum.
期刊介绍：
The European Journal of Plant Pathology is an international journal publishing original articles in English dealing with fundamental and applied aspects of plant pathology; considering disease in agricultural and horticultural crops, forestry, and in natural plant populations. The types of articles published are :Original Research at the molecular, physiological, whole-plant and population levels; Mini-reviews on topics which are timely and of global rather than national or regional significance; Short Communications for important research findings that can be presented in an abbreviated format; and Letters-to-the-Editor, where these raise issues related to articles previously published in the journal. Submissions relating to disease vector biology and integrated crop protection are welcome. However, routine screenings of plant protection products, varietal trials for disease resistance, and biological control agents are not published in the journal unless framed in the context of strategic approaches to disease management.
