摘要

Colletotrichum gloeosporioides 复合菌种包括许多植物病原菌,可在多种寄主植物上引起炭疽病,似乎分布于全球各地。韩国农业培养物保藏中心(KACC)保藏了 71 个从韩国不同植物和地理区域分离出来的该复合菌种中的 Colletotrichum 分离物。其中大部分是根据寄主和形态特征进行鉴定的,这可能导致种名不准确。因此,本研究利用六个位点(包括内部转录间隔、gapdh、chs-1、his3、act 和 tub2)的 DNA 序列分析对 KACC 分离物进行了重新鉴定。根据系统进化分析,KACC 菌株被归入 12 个已知种和 3 个候选新种。检测到的物种为 C. siamense(n = 20)、C. fructicola(n = 19)、C. gloeosporioides(n = 9)、C. aenigma(n = 5)、C. camelliae(n = 3)、C.temperatum(n = 3)、C. musae(n = 2)、C. theobromicola(n = 2)、C. viniferum(n = 2)、C. alatae(n = 1)、C. jiangxiense(n = 1)和 C. yulongense(n = 1)。其中,C. jiangxiense、C. temperatum、C. theobromicola 和 C. yulongense 是韩国未记录的物种。寄主植物比较显示,韩国新报道了 27 种真菌-寄主关系。不过,植物与真菌之间的相互作用还需要通过致病性试验进行研究。

Re-identification of Colletotrichum gloeosporioides Species Complex Isolates in Korea and Their Host Plants.

The Colletotrichum gloeosporioides species complex includes many phytopathogenic species, causing anthracnose disease on a wide range of host plants and appearing to be globally distributed. Seventy-one Colletotrichum isolates in the complex from different plants and geographic regions in Korea were preserved in the Korean Agricultural Culture Collection (KACC). Most of them had been identified based on hosts and morphological features, this could lead to inaccurate species names. Therefore, the KACC isolates were re-identified using DNA sequence analyses of six loci, comprising internal transcribed spacer, gapdh, chs-1, his3, act, and tub2 in this study. Based on the combined phylogenetic analysis, KACC strains were assigned to 12 known species and three new species candidates. The detected species are C. siamense (n = 20), C. fructicola (n = 19), C. gloeosporioides (n = 9), C. aenigma (n = 5), C. camelliae (n = 3), C. temperatum (n = 3), C. musae (n = 2), C. theobromicola (n = 2), C. viniferum (n = 2), C. alatae (n = 1), C. jiangxiense (n = 1), and C. yulongense (n = 1). Of these, C. jiangxiense, C. temperatum, C. theobromicola and C. yulongense are unrecorded species in Korea. Host plant comparisons showed that 27 fungus-host associations are newly reported in the country. However, plant-fungus interactions need to be investigated by pathogenicity tests.
