简介：
Overview
This article presents a protocol for obtaining amplicon sequence data from soil, rhizosphere, and root endosphere microbiomes. The method aims to characterize the composition and diversity of plant-associated microbial communities.
Key Study Components
Area of Science
- Microbial Ecology
- Plant-Microbe Interactions
- Community Profiling
Background
- The root microbiome consists of various compartments, including soil, rhizosphere, and root endosphere.
- Understanding these compartments can reveal the factors influencing microbiome structure.
- 16S ribosomal RNA gene profiling is a standard method for studying microbial communities.
- This protocol standardizes the process from sample collection to sequencing library preparation.
Purpose of Study
- To characterize the root microbiome across different compartments.
- To investigate the drivers of microbiome structure.
- To provide a standardized protocol for researchers.
Methods Used
- Collection of bulk soil samples using an ethanol-sterilized soil core collector.
- Sampling at a depth of 23 to 30 centimeters from the base of the plant.
- Separation of root and rhizosphere for analysis.
- DNA extraction and preparation of sequencing libraries.
Main Results
- Standardized protocol facilitates consistent microbiome analysis.
- Provides insights into the composition of plant-associated microbial communities.
- Enables investigation of biotic and abiotic factors affecting microbiome structure.
- Demonstrated by a graduate student in the Coleman-Derr Laboratory.
Conclusions
- The protocol is suitable for a wide range of plant species.
- It enhances understanding of microbial diversity in plant environments.
- Future applications can expand knowledge in microbial ecology.
