Research on Abiotic Stresses

Research targeting drought, flooding, temperature and nutrient stress constitutes a central theme. Singh’s team employs field and controlled environment platforms to dissect genotype-by-environment interactions, phenotype adaptive root and shoot traits, and identify QTL underlying abiotic stress tolerance. A notable contribution was the conceptualization and development of Near-Field Abiotic Stress Tolerance (N-FAST) system for screening multiple abiotic stress and nutrient deficiency traits. Results have elucidated mechanisms of drought adaptation and flooding tolerance and have been translated into high yielding and stress-adapted soybean lines with enhanced resilience. Precision phenotyping and predictive modeling advance understanding of plasticity in response to environmental variability, with actionable insights for breeding weather-resilient cultivars.
