Unveiling the root-rhizosphere environment of perennial wheat: a metabolomic perspective.

ABSTRACT:

Background

Perennial grain roots grow continuously, enhancing soil carbon sequestration and forming a "holobiont" with the microbiome, essential for nutrient acquisition and stress resilience. Consequently, perennial grains serve as ideal models for investigating long-term dynamics between root systems and the rhizosphere environment. Despite their potential, the rhizosphere environment of perennial grains remains underexplored. This research utilizes an untargeted metabolomic approach to characterize the root-rhizosphere molecular signals in four new perennial grain (NPGs) lines named 235a, 280b, 11,955, and OK72, across four years of growth.

Results

Metabolomic analysis annotated 2,527 metabolites, most of which originated from fungi (30.3%), bacteria (23%), and plants (15
