Wheat Rhizosphere Microbiome
This repository contains the processed datasets, analysis scripts, intermediate files, and figures associated with the study: Differential drought sensitivity of total and active wheat rhizosphere microbiome during rainfall reduction
The project investigates how reduced rainfall influences the structure, activity, and functional responses of the wheat rhizosphere microbiome using an integrated multi-omics approach combining metagenomics, metatranscriptomics, and volatile organic compound (VOC) profiling.
Experimental Design
Two wheat genotypes with contrasting drought responses were evaluated under field conditions:
• DS – Drought-sensitive genotype
• DT – Drought-tolerant genotype
Rainfall was manipulated using four precipitation treatments:
• 100% rainfall (control)
• 75% rainfall
• 50% rainfall
• 25% rainfall
Differential analyses were performed by comparing each reduced-rainfall treatment to the 100% rainfall control.
