摘要 中英对照阅读
草莓(Fragaria × ananassa)是世界上栽培最广泛的浆果之一。它们不仅美味多汁、营养丰富,还具有重要的经济价值。然而,目前关于与草莓相关的内生细菌的研究相对有限。这项工作提供了对三种草莓品种(White Elves、Tokun 和 Akihime)在三个生态位(根、茎和叶)中的细菌群落组成和多样性的全面描述。研究表明,草莓细菌群体的多样性和组成在地下生态位(根部)与地上部分(茎和叶片)之间存在显著差异。对于这三个品种的所有生态位而言,细菌多样性和丰富度都有所不同;从根部到茎再到叶片,多样性显著降低。Akihime 茎和叶中的细菌群落的丰富度和 alpha 多样性显著低于 White Elves。有益细菌属(如 Ochrobacter、Bradyrhizobium、Sphingomonas 和 Pseudolobrys)在 White Elves 和 Tokun 中比 Akihime 更为丰富,特别是在根部和茎中。本研究的结果为发现新物种或基因变异以提高宿主适应性和抗逆性提供了重要参考。还需要进一步的研究来揭示植物与内生细菌之间的相互作用以及从这些细菌中提取生物活性化合物的潜力。
