Abstract

Olive anthracnose, caused by Colletotrichum species, is one of the most destructive fungal diseases affecting olive fruit worldwide. With the expansion of olive cultivation into East Asia, including Jeju Island, South Korea, it is necessary to characterize local Colletotrichum populations. This study investigated Colletotrichum species associated with olive anthracnose in Korea and their pathogenicity. Using morphological characterization and multilocus phylogenetic analysis (ITS, GAPDH, CHS-1, ACT, and TUB2), we found that four Colletotrichum species are associated with olive anthracnose in Korea: C. fioriniae, C. nymphaeae, C. fructicola, and C. siamense. Pathogenicity tests confirmed that all four species cause typical anthracnose symptoms on olives, confirming their role as causal agents of olive anthracnose in Korea.

韩国橄榄炭疽病相关炭疽菌的鉴定与鉴定。

橄榄炭疽病是世界上最具破坏性的橄榄果实真菌病害之一，由炭疽菌引起。随着橄榄树种植扩展到东亚，包括韩国济州岛，有必要对当地炭疽菌种群进行表征。本研究调查了韩国橄榄炭疽病相关炭疽菌种类及其致病性。通过形态学表征和多位点系统发育分析（ITS、GAPDH、CHS-1、ACT和TUB2），我们发现韩国有4种炭疽菌与橄榄炭疽病相关：C. fioriniae、C. nymphaeae、C. fructicola和C. siamense。致病性测试证实，所有四种都能在橄榄上引起典型的炭疽病症状，证实它们是韩国橄榄炭疽病的致病因子。

期刊介绍： Mycobiology is an international journal devoted to the publication of fundamental and applied investigations on all aspects of mycology and their traditional allies. It is published quarterly and is the official publication of the Korean Society of Mycology. Mycobiology publishes reports of basic research on fungi and fungus-like organisms, including yeasts, filamentous fungi, lichen fungi, oomycetes, moulds, and mushroom. Topics also include molecular and cellular biology, biochemistry, metabolism, developmental biology, environmental mycology, evolution, ecology, taxonomy and systematics, genetics/genomics, fungal pathogen and disease control, physiology, and industrial biotechnology using fungi.
