摘要

草莓是中国重要的经济作物，产量和种植面积均居世界前列。然而，采后腐烂严重影响草莓的质量和保质期。本研究采自辽宁省丹东市具有典型腐病症状的草莓果实。真菌分离物CMG2-3根据菌落、柱头和分生孢子形态初步鉴定为Epicoccum spp.。随后利用ITS、LSU和tub2序列进行多位点系统发育分析，证实CMG2-3属于E. sorghinum。人工接种致病性试验证实了高粱芽孢杆菌是草莓果腐病的致病因子。据我们所知，这是首次报道高粱芽孢杆菌与草莓采后腐病有关。这些发现为草莓采后病害的研究提供了新的视角，为草莓果腐病的防治奠定了理论基础。

First report of Epicoccum sorghinum causing postharvest fruit rot of strawberry in China

Strawberry is an important economic crop in China, with the country leading the world in both production and cultivation area. However, postharvest fruit rot severely compromises strawberry quality and shelf life. In this study, strawberry fruits exhibiting typical rot symptoms were collected from Dandong City, Liaoning Province. The fungal isolate CMG2-3 was tentatively identified as Epicoccum spp. based on colony, pycnidia, and conidial morphology. Subsequent multi-locus phylogenetic analysis using ITS, LSU, and tub2 sequences confirmed that CMG2-3 belonged to E. sorghinum. Pathogenicity tests using artificial inoculation confirmed E. sorghinum as the causal agent of strawberry fruit rot. To our knowledge, this is the first report implicating E. sorghinum in postharvest strawberry rot. These findings provide a new perspective on postharvest strawberry diseases and lay a theoretical foundation for the management of strawberry fruit rot.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
