将基于DNA的社区成员身份与基于RNA的蛋白质合成潜力 (PSP) 进行比较,作为微生物活动的代理.
为了识别特定的细菌群体和代谢功能,在树叶圈中丰富.

主要方法:

16S rRNA基因 (DNA) 测序用于总细菌社区成员.
16S rRNA转录 (RNA) 测序以确定蛋白质合成潜力 (PSP).
在根球和土壤样本中对DNA和RNA资料进行比较分析.

主要成果:

与DNA测序相比,PSP分析揭示了树根球细菌属的微小差异.
DNA测序过高估计了Sacharibacteria和Gemmatimonadetes,同时低估了关键的根协会者,如Comamonadaceae.

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
