Abstract excerpt

Exploiting natural variation to uncouple yield from nitrogen (N) input is essential for sustainable oilseed rape production. Here, we screened 505 accessions and discovered a 10-fold gradient in chlorate (ClO₃⁻) sensitivity that mirrors genotypic differences in nitrogen use efficiency (NUE). Chlorate-sensitive genotypes (CSG) exhibited 35% higher ¹⁵NO₃⁻ influx, 40%-62% greater root glutamine synthetase (GS)...
