Excavation of plant roots from the field as well as processing of samples into endosphere, rhizosphere, and soil are described in detail, including DNA extraction and data analysis methods. This paper is designed to enable other laboratories to use these techniques for the study of soil, endosphere, and rhizosphere microbiomes.

We describe a protocol to sample, preserve, and section intact roots and the surrounding rhizosphere soil from wetland environments using rice (Oryza sativa L.) as a model species. Once preserved, the sample can be analyzed using elemental imaging techniques, such as synchrotron X-ray fluorescence (XRF) chemical speciation imaging.

Here, we describe a protocol to obtain amplicon sequence data of soil, rhizosphere, and root endosphere microbiomes. This information can be used to investigate the composition and diversity of plant-associated microbial communities, and is suitable for the use with a wide range of plant species.
FAQs
Root exudates act as chemical inputs that can modify nearby pH, nutrient availability, microbial communities, and enzyme activity. Because these changes occur together, measuring exudate-related effects helps connect plant activity with shifts in soil chemistry and biology. This perspective allows researchers to evaluate how plants influence nutrient cycling, soil health, and interactions with surrounding microorganisms.
These variables describe linked parts of the rhizosphere environment rather than isolated measurements. Moisture can affect chemical conditions and biological activity, while pH influences nutrient availability and microbial responses. Considering them together helps researchers explain why the same plant may produce different soil outcomes under different environmental conditions, improving interpretation of fertility, contamination, and ecosystem-function data.
Each tool captures a different level of evidence. Microscopy can show relevant biological features in the sampled soil, chemical assays can characterize conditions such as nutrients or pH, and molecular tools can examine microbial communities. Combining these approaches links visible, chemical, and biological observations, producing a more integrated account of plant-microbe relationships and soil processes.
A practical workflow connects sampling with complementary measurements. Researchers select sampling methods for root-influenced soil, then assess variables such as exudates, nutrients, pH, moisture, microbial communities, or enzyme activity using analytical tools. Interpreting these results together can show how roots modify local conditions and how soil organisms respond, rather than treating each measurement as unrelated.
Environmental researchers can apply it when they need to understand how roots and soil organisms respond to contamination. Measurements of chemical conditions, microbial communities, and enzyme activity can help assess pollutant transformation in the root zone. The resulting evidence supports evaluation of contamination effects and identifies how vegetation may influence soil processes in affected environments.
In phytoremediation studies, the analysis helps examine how vegetation interacts with contaminated soil and whether root-associated processes correspond with pollutant transformation. In broader environmental work, it can also inform soil-fertility assessment and predictions about ecosystem function under changing conditions. Its value comes from linking plant activity, soil properties, and biological responses within the same local system.
