摘要

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.
