The bacterial microbiome plays crucial role in plants' resistance to diseases, nutrient uptake and productivity. We examined the microbiome characteristics of healthy and unhealthy strawberry farms, focusing on soil (bulk soil, rhizosphere soil) and plant (roots and shoots). The relative abundance of most abundant taxa were correlated with the chemical soil properties and shoot niche revealed the least amount of significant correlations between the two. While alpha and beta diversities did not show differences between health groups, we identified a number of core taxa (16-59) and marker bacterial taxa for each healthy (Unclassified Tepidisphaerales, Ohtaekwangia, Hydrocarboniphaga) and dysbiotic (Udaeobacter, Solibacter, Unclassified Chitinophagales, Unclassified Nitrosomonadaceae, Nitrospira, Nocardioides, Tardiphaga, Skermanella, Pseudomonas, Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium, Curtobacterium) niche. We also revealed selective pressure of strawberry rhizosphere soil and roots plants in unhealthy plantations increased stochastic ecological processes of bacterial microbiome assembly in shoots. Our findings contribute to understanding sustainable agriculture and plant-microbiome interactions.
细菌微生物组在植物的疾病抗性、养分吸收和生产力方面发挥着关键作用。我们研究了健康和不健康草莓农场的微生物组特征，重点是土壤（原状土、根际土）和植物（根和茎）。大多数丰度较高的分类群的相对丰度与土壤化学性质相关，而茎部小生境揭示了两者之间相关性最小。虽然健康组之间的 alpha 和 beta 多样性没有差异，但我们确定了一些核心分类群（16-59 个）和每个健康（未分类的 Tepidisphaerales、Ohtaekwangia、Hydrocarboniphaga）和失调（Udaeobacter、Solibacter、未分类的 Chitinophagales、未分类的 Nitrosomonadaceae、Nitrospira、Nocardioides、Tardiphaga、Skermanella、Pseudomonas、Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium、Curtobacterium）小生境的标记细菌分类群。我们还揭示了草莓根际土壤和根的选择性压力，在不健康的种植园中增加了茎部细菌微生物组组装的随机生态过程。我们的研究结果有助于理解可持续农业和植物-微生物组相互作用。
