The genus Curvularia comprises globally distributed phytopathogenic fungi that predominantly infect grasses, including various Medicinal and Aromatic Plants (MAPs). Despite its ecological and agricultural significance, studies on the morphology, phenotypic diversity, and infection mechanisms of Curvularia in MAPs remains scarce. Taxonomic understanding of this genus has also evolved over time, with repeated revisions and reclassifications. This review presents a chronicle key discovery, taxonomic updates, and systematic advancements in Curvularia research. Known to severely impact the Poaceae family, staple crops, and MAPs (Rauvolfia, Ocimum spp., Aloe vera, and Curcuma spp.) Curvularia employ diverse genes to disrupt host metabolic pathways, inducing physiological dysfunctions disease symptoms. Here, we consolidate global reports on Curvularia-associated diseases in MAPs, analysing host-pathogen interactions across geographical regions. Furthermore, we explore the disease cycle, biochemical infection strategies, and molecular pathogenesis to elucidate fungal virulence. A dedicated focus is placed on Curvularia-derived secondary metabolites and toxins, highlighting their role in host manipulation and pathogenicity. By integrating these insights, this review aims to address critical knowledge gaps and direct future research on Curvularia-MAPs interactions.
弯孢属包含全球分布的植物病原真菌，主要感染禾本科植物，包括各种药用和芳香植物（MAPs）。尽管其具有生态和农业重要性，但关于弯孢属在MAPs中的形态学、表型多样性和感染机制的研究仍然很少。随着时间的推移，对该属的分类学认识也在不断演变，经历了多次修订和重新分类。本综述呈现了弯孢属研究中的重要关键发现、分类学更新和系统性进展。弯孢属已知会严重影响禾本科植物、主要作物以及MAPs（萝芙木属、罗勒属植物、库拉索芦荟和姜黄属植物），它利用多种基因破坏宿主代谢途径，引发生理功能障碍和疾病症状。在此，我们汇总了关于MAPs中与弯孢属相关疾病的全球报告，分析了不同地理区域的宿主 - 病原体相互作用。此外，我们探究了疾病循环、生化感染策略和分子发病机制，以阐明真菌的毒力。我们特别关注弯孢属产生的次生代谢产物和毒素，强调它们在操纵宿主和致病性方面的作用。通过整合这些见解，本综述旨在填补关键的知识空白，并指导未来关于弯孢属与MAPs相互作用的研究。
