Title of Project Proposal

Geospatial-Genomic Mapping of Pest-Pathogen Dynamics for Next-Gen Biocontrol Solutions in Natural Farming Systems Across Agroclimatic Zones of India

Abstract

This project integrates Geographic Information System (GIS) mapping, Genome-Wide Association Studies (GWAS), and multi-omics profiling to map pest-pathogen dynamics and identify climate-resilient biocontrol solutions in natural farming systems across India’s agroclimatic zones. Native microbes will be isolated and characterized for antagonistic potential, with mechanisms studied via transcriptomics, metabolomics, and molecular docking. Predictive models will integrate genomic, climatic, and spatial data for optimized, region-specific biocontrol deployment, contributing to sustainable, chemical-free pest management.

Objectives

  1. To map the pest-pathogen distribution across India’s agroclimatic zones using Geographic Information System (GIS) and characterize their genetic diversity through Genome-WideAssociation Studies (GWAS), identifying virulence hotspots.
  2. To isolate native microbes from natural farming systems and evaluate their antagonistic potential via; In vitro assays (dual culture, metabolite inhibition), multi-omics integration(metagenomics/metabolomics of biocontrol agent-pathogen interactions), Molecular docking to predict effector protein–metabolite binding for biocontrol strain prioritization.
  3. To decipher biocontrol modes of action using: Transcriptomics/qPCR (host/pathogen gene expression under biocontrol), Microscopy (colonization efficiency), In silico modelling ofbiocontrol agent efficacy under climate variables.

Technical Details (Brief)

Multi-location sampling, GPS data integration, GWAS-based virulence profiling, microbial isolation & screening, genome sequencing of promising strains, multi-omics profiling, molecular docking studies, and predictive modelling for region-specific, climate-adapted deployment strategies.

Project Duration

2 years (2026–2027)

Expected Impact

Development of a geospatial-genomic database, identification of 5 high-potential microbial strains, reduced pest-related losses, 30–40% reduction in input costs, enhanced climate resilience in natural farming, and open-access decision-support tools for farmers.
