Plant-associated bacteria are critical for plant growth and health. However, the effects of plant growth stages on the bacterial community remain unclear. Analyses of the microbiome associated with field-grown soybean revealed a marked shift in the bacterial community during the growth stages. The relative abundance of Methylorubrum in the leaf and stem increased from 0.2% to more than 45%, but decreased to approximately 15%, with a peak at the flowering stage at which nitrogen metabolism changed in the soybean plant. These results suggest the significance of a time-series analysis for understanding the relationship between the microbial community and host plant physiology.

大豆植物组织中生长阶段依赖性细菌群落：甲基红细菌在大豆芽的开花阶段短暂占主导地位


植物相关细菌对于植物生长和健康至关重要。然而，植物生长阶段对细菌群落的影响仍不清楚。对田间种植大豆相关微生物组的分析显示，在生长阶段细菌群落发生了显着变化。叶和茎中甲基红藻的相对丰度从0.2%增加到45%以上，但下降到15%左右，在大豆植株氮代谢发生变化的开花期达到峰值。这些结果表明时间序列分析对于理解微生物群落与宿主植物生理学之间的关系具有重要意义。
