植物微生物组及其操纵预示着植物生物技术的新时代，具有有益于可持续作物生产的潜力。然而，评估重要经济作物微生物群的多样性，结构和影响的研究仍然很少。在这里，我们描述了与甘蔗相关的细菌和真菌群落的结构和组合的全面清单。我们的分析鉴定了23，811个细菌OTU和意想不到的11，727个真菌OTU，它们栖息在根、芽和叶的内生和外生隔室中。这些群落主要起源于植物周围的原生土壤，并以不同的模式在植物器官中定居。样品类型是真菌群落组合的主要驱动力，而器官隔室在细菌群落组合中起着重要作用。我们确定了核心细菌和真菌群落组成的总微生物丰度不到20%，但占总微生物相对丰度的90%以上。根显示89个核心细菌科，其中19个占总相对丰度的44%。秸秆主要由酵母菌群组成，占总相对丰度的12%以上。本文描述的核心微生物组包括其生物学作用是植物生长和发酵过程中重要性状的基础的群体。
Plant microbiome and its manipulation herald a new era for plant biotechnology with the potential to benefit sustainable crop production. However, studies evaluating the diversity, structure and impact of the microbiota in economic important crops are still rare. Here we describe a comprehensive inventory of the structure and assemblage of the bacterial and fungal communities associated with sugarcane. Our analysis identified 23,811 bacterial OTUs and an unexpected 11,727 fungal OTUs inhabiting the endophytic and exophytic compartments of roots, shoots, and leaves. These communities originate primarily from native soil around plants and colonize plant organs in distinct patterns. The sample type is the primary driver of fungal community assemblage, and the organ compartment plays a major role in bacterial community assemblage. We identified core bacterial and fungal communities composed of less than 20% of the total microbial richness but accounting for over 90% of the total microbial relative abundance. The roots showed 89 core bacterial families, 19 of which accounted for 44% of the total relative abundance. Stalks are dominated by groups of yeasts that represent over 12% of total relative abundance. The core microbiome described here comprise groups whose biological role underlies important traits in plant growth and fermentative processes.
