LondonOne wheat gene breaks a decades-old tradeoff.
The trait lets nitrogen-poor and gas-poor states match the same yield on far less imported fertilizer.
Researchers found the TaNPF7.6-A1 allele boosts nitrogen uptake without cutting grain yield, unlike prior nitrogen-saving variants.
The study is an accepted, not final, version, with field performance across climates still unproven.
