Metabolomic Signatures of Nitrogen Stress in Maize: A Dataset Across Six Genotypes and Four Regimes

Abstract

Metabolomic Signatures of Nitrogen Stress in Maize has moved quickly from a research idea to something a working breeding or
production programme can actually use, but the evidence behind it has not always kept pace. We pull together the current
evidence for metabolomic signatures of nitrogen stress in maize, covering the methodological, practical, regulatory and cost
angles, with an eye on where practice has genuinely settled and where researchers and regulators are still largely working it out
for themselves. Selective, context-specific adoption looks better supported by the evidence gathered here than either broad rollout
or blanket avoidance.
