The high potential of sea buckthorn, black chokeberry, red and white currants in healthy food industry boosted interest in the plant cultivation. The present study is the first work providing comprehensive information on microbial populations of these berries. Next Generation Sequencing allowed identification of eukaryotic and prokaryotic microorganisms prevalent on specific berries, including uncultivable microorganisms. Our study revealed the broad diversity of berries-associated bacterial and fungal microorganisms. Analysis of representative microbial OTUs showed a clear separation among inhabitants of sea buckthorn, black chokeberry and both currants, indicating plant-defined differences in the composition of the bacterial and fungal microbiota. Among the microorganisms distributed on tested berries, we documented potentially beneficial fungi and bacteria along with potential phytopathogens or those harmful for humans. Thus, plant microbiota appears to be highly relevant for the evaluation of the microbiota impact on food quality and human health.

沙棘，黑苦莓，红和白葡萄干在健康食品工业中的巨大潜力激发了人们对植物种植的兴趣。本研究是提供有关这些浆果的微生物种群的全面信息的第一项工作。下一代测序可以鉴定在特定浆果上普遍存在的真核和原核微生物，包括不可培养的微生物。我们的研究揭示了浆果相关细菌和真菌微生物的广泛多样性。对代表性微生物OTU的分析表明，沙棘，黑苦莓和两种黑加仑的居民之间存在明显的分离，表明细菌和真菌菌群组成的植物定义差异。在散布在经过测试的浆果上的微生物中，我们记录了潜在有益的真菌和细菌以及潜在的植物病原体或对人体有害的病原体。因此，植物微生物群似乎与评估微生物群对食品质量和人类健康的影响高度相关。
