Abstract
Fusarium sambucinum species complex (FSAMSC) is an important taxonomic group, causing severe plant diseases. Many studies were carried out on FSAMSC plant diseases in Korea, but only 2 species (F. graminearum, F. sambucinum) from 14 host plants were registered in the List of Plant Disease in Korea. To clarify FSAMSC diversity and their pathogenecity, we examined FSAMSC isolates preserved in the Korean Agricultural Culture Collection. Fifty-seven strains were reidentifed as 7 species (F. asiaticum, F. graminearum, F. vorosii, F. meridionalei, F. boothii, F. kyushuense, F. armeniacum) based on multi-locus sequence typing analysis. According to previous reports and result of this study, 5 species (F. asiaticum, F. graminearum, F. vorosii, F. armeniacum, F. sambucinum) were pathogenic on 24 host plants in FSAMSC, while the pathogenicity of 3 species (F. meridionalei, F. boothii, F. kyushuense) were not clear.
桑布西镰刀菌物种复合体（Fusarium sambucinum species complex，FSAMSC）是一个重要的分类学类群，可引起严重的植物病害。韩国对FSAMSC植物病害进行了大量研究，但在《韩国植物病害名录》中仅登记了14种寄主植物中的2个物种（禾谷镰刀菌、桑布西南镰刀菌）。为了阐明FSAMSC的多样性及其致病性，我们检测了保存在韩国农业文化收藏中的FSAMSC分离株。根据多基因座序列分型分析，将57个菌株重新鉴定为7个种（亚洲F.asiaticum、禾谷F.graminearum、沃氏F.vorosii、子午线F.meridionalei、靴形F.boothii、九州F.kyushuense、亚美尼亚F.armeniacum）。根据以往的报道和本研究的结果，在FSAMSC中，有5种（亚洲F.asiaticum、禾谷F.graminearum、沃罗西F.vorosii、亚美尼亚F.armeniacum、桑布西F.sambucinum）对24种寄主植物具有致病性，而3种（美国F.meridionalei、英国F.boothii、日本F.kyushuense）的致病性尚不清楚。
