摘要

炭疽菌是国内外公认的引起炭疽病的重要植物病原体,其寄主植物种类繁多。韩国农业文化收藏(KACC)中保存的炭疽病分离株是韩国科学研究和炭疽病管理战略的重要资源。许多炭疽菌分离株已被存款人根据形态特征和寄主植物进行鉴定,这可能导致物种名称不准确。因此,本研究通过对38株KACC的核糖体内转录间隔物、甘油三酯-3-磷酸脱氢酶(gapdh)、几丁质合成酶1 (chs-1)、组蛋白-3 (his3)的多位点序列分析,将其重新鉴定为13个已知种(C. boninense、C. caudasporum、C. coccodes、C. echinochloae、C. karsti、C. liriopes、C. nigrum、C. sansevieriae、C. spaethianum、C. sublineola、C. sydowii、C. truncatum、C. zhaoqingense)和一个新的候选种。肌动蛋白(act), β -微管蛋白2 (tub2)和锰超氧化物歧化酶(sod2)。其中,C. caudasporum、C. echinochloae和C. zhaoqingense为韩国未记录种。结果还发现了16种新的寄主-真菌组合,其中包括13种新的世界组合。然而,本研究中真菌种类对宿主的致病性尚未得到证实。

Re-assessment of Taxonomy and Host Range of Colletotrichum from Korea: Focus on the C. boninense, C. spaethianum Species Complexes, and Related Taxa.

Colletotrichum species are commonly known as important phytopathogens causing anthracnose in Korea and worldwide, with a diverse range of host plants. Colletotrichum isolates preserved in the Korean Agricultural Culture Collection (KACC) are important resources for scientific research as well as anthracnose disease management strategies in Korea. Many Colletotrichum isolates in KACC had been identified using morphological characteristics and their host plants by depositors, this could lead to inaccurate species names. In this study, 38 KACC isolates were, therefore, re-identified as 13 known species (C. boninense, C. caudasporum, C. coccodes, C. echinochloae, C. karsti, C. liriopes, C. nigrum, C. sansevieriae, C. spaethianum, C. sublineola, C. sydowii, C. truncatum, and C. zhaoqingense) and a new species candidate, based on multi-locus sequence analyses of the nuclear ribosomal internal transcribed spacers, glyceraldehyde-3-phosphate dehydrogenase (gapdh), chitin synthase 1 (chs-1), histone-3 (his3), actin (act), beta-tubulin 2 (tub2), and manganese-superoxide dismutase (sod2). Of these, C. caudasporum, C. echinochloae, and C. zhaoqingense are unrecorded species in Korea. The results also revealed 16 new host-fungus combinations in Korea, including 13 new combinations worldwide. However, the pathogenicity of the fungal species in this work on their hosts was not confirmed.
