SUMMARY Colletotrichum acutatum causes anthracnose on a wide range of hosts including woody and herbaceous crops, ornamentals, fruits and conifers. Almond, citrus, lupin, olive and strawberry are some of the crops in which C. acutatum diseases are economically important. With the application of molecular markers and diagnostic PCR over the last 10-15 years, C. acutatum was identified as a major pathogen on a number of hosts instead of or along with C. gloeosporioides. C. acutatum displays high levels of genotypic and phenotypic diversity. The global populations of this cosmopolitan pathogen fit into at least eight distinct molecular groups, A1-A8, which show some degree of correlation with the morphological characteristics and varying patterns of host association and geographical distribution. The pathogen has complex epidemiology, exhibiting pathogenic and non-pathogenic lifestyles on target hosts, non-target crops and weeds. C. acutatum populations also show pathogenic variability and cross-infection potential in relation to a number of hosts. Molecular genetic tools are being developed to investigate the pathogenicity mechanisms of this key pathogen. This article mainly focuses on the global population diversity in C. acutatum, pathogen epidemiology and diagnosis, host colonization processes, and the development of tools for the identification and analysis of genes associated with pathogenicity. Background information on the pathogen origin, host range, disease symptoms and disease management strategies is also provided.
总结 炭疽菌属（Colletotrichum acutatum）引起广泛宿主的炭疽病，包括木本和草本作物、观赏植物、水果和针叶树。杏仁、柑橘、羽扇豆、橄榄和草莓是炭疽菌属疾病在经济上重要的一些作物。在过去 10-15 年中，随着分子标记和诊断 PCR 的应用，炭疽菌属被鉴定为许多宿主的主要病原体，而不是或与胶孢炭疽菌（C. gloeosporioides）一起。炭疽菌属表现出高度的基因型和表型多样性。这种世界性的病原体的全球种群至少可分为八个不同的分子群，A1-A8，它们与形态特征以及宿主相关性和地理分布的不同模式有一定程度的相关性。该病原体具有复杂的流行病学特征，在靶宿主、非靶作物和杂草上表现出致病性和非致病性生活方式。炭疽菌属种群也与许多宿主相关表现出致病性变异性和交叉感染潜力。正在开发分子遗传工具来研究这种关键病原体的致病性机制。本文主要关注炭疽菌属的全球种群多样性、病原体流行病学和诊断、宿主定殖过程，以及与致病性相关的基因鉴定和分析工具的开发。还提供了关于病原体起源、宿主范围、病症和疾病管理策略的背景信息。
