Integrating metabolomics and high-throughput phenotyping to elucidate metabolic and phenotypic responses to early-season drought stress in Nordic spring wheat.

ABSTRACT:

Background

Understanding the metabolic responses of wheat to drought stress is essential for developing strategies to enhance its resilience under water-deficit conditions. In this study, we investigated the metabolic and phenotypic responses of twelve Nordic spring wheat genotypes subjected to drought stress over 28 days in a high-throughput phenotyping facility. By integrating metabolic profiling with phenotypic assessments, we aimed to identify key metabolites and traits associated with drought tolerance.

Results

We identified nearly 200 metabolites that were differentially accumulated across four time points, including early drought and recovery phases. Of these, 25% were organic acids, 16.2% sugars and derivatives, 16.2% amino acids and derivatives, and 10.4% alkaloids,
