Core-microbiome approach to enhance silicon acquisition and stress tolerance in crops
A research-driven approach that uses silicon application to modulate the core microbiome of crops in their native environment, improving nutrient uptake, stress tolerance, and sustainable yield. Combines plant physiology, metagenomics, and metatranscriptomics to identify beneficial microbial communities that enhance silicon acquisition.
Overview
This solution explores how silicon (Si) application influences the core microbiome of crops grown in their native environment to improve plant growth, nutrient uptake, and tolerance to abiotic stresses such as drought, heat, flooding, and heavy metals. By identifying and characterizing the beneficial microbial communities in the endosphere and rhizosphere, the research aims to develop eco-friendly strategies for sustainable crop yield. The approach addresses a critical gap in understanding how silicon interacts with plant-associated microbiomes, offering a pathway to leverage natural microbial functions for improved plant performance.
Technical specifications
Key features and methodology:
- Application of optimized silicon concentrations to crops in native growing environments
- Selection of plants with superior phenotypic performance for microbiome analysis
- DNA extraction and metagenomic sequencing of endospheric and rhizospheric microbiomes
- Bioinformatic analysis to map core-microbiome structure and variability
- Metatranscriptomic profiling to assess gene activation involved in nutrient uptake and translocation
- Nutrient profiling to correlate core-microbiome function with silicon acquisition and cycling
- Integration with established knowledge of silicon's role in regulating oxidative stress and phytohormonal networks including abscisic acid and salicylic acid
Technology readiness level
The research is at an early-to-mid stage of development. Prior work has demonstrated that silicon application significantly improves plant growth and stress tolerance through regulation of oxidative stress, phytohormones, and gene regulatory networks. The next phase involves experimental validation using metagenomics and metatranscriptomics in native field environments to establish the relationship between silicon application and core-microbiome structure. Further validation and field trials are needed before commercial application.
