We present the first worldwide study on the apple (Malus × domestica) fruit microbiome that examines questions regarding the composition and the assembly of microbial communities on and in apple fruit. Results revealed that the composition and structure of the fungal and bacterial communities associated with apple fruit vary and are highly dependent on geographical location. The study also confirmed that the spatial variation in the fungal and bacterial composition of different fruit tissues exists at a global level. Fungal diversity varied significantly in fruit harvested in different geographical locations and suggests a potential link between location and the type and rate of postharvest diseases that develop in each country. The global core microbiome of apple fruit was represented by several beneficial microbial taxa and accounted for a large fraction of the fruit microbial community. The study provides foundational information about the apple fruit microbiome that can be utilized for the development of novel approaches for the management of fruit quality and safety, as well as for reducing losses due to the establishment and proliferation of postharvest pathogens. It also lays the groundwork for studying the complex microbial interactions that occur on apple fruit surfaces.
我们展示了第一项关于苹果（Malus × domestica）果实微生物组的全球研究，该研究探讨了有关苹果果实表面和内部微生物群落的组成与组装的问题。结果表明，与苹果果实相关的真菌和细菌群落的组成和结构各不相同，并且高度依赖于地理位置。该研究还证实，不同果实组织的真菌和细菌组成的空间变异在全球范围内存在。在不同地理位置收获的果实中，真菌多样性差异显著，这表明地理位置与每个国家收获后发生的病害类型和发生率之间可能存在联系。苹果果实的全球核心微生物组由几种有益的微生物类群代表，并且在果实微生物群落中占很大比例。该研究提供了有关苹果果实微生物组的基础信息，可用于开发管理果实质量和安全的新方法，以及减少由于采后病原体的建立和增殖造成的损失。它还为研究苹果果实表面发生的复杂微生物相互作用奠定了基础。
