摘要

背景：藏红花（Crocus sativus L.）是一种具有重要药用价值的中草药，在世界范围内被广泛种植。然而，真菌病原菌诱导的球茎腐病对藏红花种植构成了重大挑战，造成了巨大的经济损失，长期以来一直受到研究人员和行业专业人士的关注。本研究旨在利用高通量测序技术准确、快速地鉴定藏红花（Fusarium oxysporum f. sp. crocus， FOSC）特异性病原体。结果：高通量测序成功证实FOSC是藏红花球茎腐病的病原体，随后的耐受性基因预测表明其对多种抗生素具有耐药性。在8种植物精油中，肉桂精油（CC-EO）对FOSC的抗真菌活性最强。细胞水平的研究表明，CC-EO通过破坏孢子细胞膜完整性、诱导细胞核DNA断裂和促进活性氧积累来对抗FOSC。结论：本研究首次应用高通量测序技术鉴定藏红花特异性FOSC，表明CC-EO通过其多靶点抗真菌机制在防治藏红花球茎腐病方面具有重要潜力。©2025化学工业协会。

Identification of pathogenic bacteria in saffron (Crocus sativus L.) by high-throughput sequencing and the evaluation of the antifungal properties of different plant essential oils.

Background: Saffron (Crocus sativus L.), a Chinese herbal medicine of significant medicinal value, is extensively cultivated worldwide. However, fungal pathogen-induced corm rot disease poses a major challenge to saffron cultivation, causing substantial economic losses and long-standing concern among researchers and industry professionals. The presemt study aimed to accurately and rapidly identify Fusarium oxysporum f. sp. crocus (FOSC) as a crocus-specific pathogen using high-throughput sequencing technology.

Results: High-throughput sequencing successfully confirmed FOSC as the pathogen responsible for crocus corm rot, with subsequent tolerance gene predictions indicating its resistance to multiple antibiotics. Among eight tested plant essential oils, Cinnamomum cassia essential oil (CC-EO) exhibited the strongest antifungal activity against FOSC. Cellular-level investigations revealed that CC-EO combats FOSC by compromising spore cell membrane integrity, inducing nuclear DNA fragmentation and promoting reactive oxygen species accumulation.

Conclusion: This study represents the first application of high-throughput sequencing to identify the crocus-specific FOSC, and demonstrates that CC-EO holds significant potential for preventing and controlling saffron corm rot through its multi-target antifungal mechanism. © 2025 Society of Chemical Industry.
