Other claims from this paper (7)
- Intervention effect Under low nitrate conditions H158 showed enhanced antioxidant capacity, nitrogen assimilation and nitrogen uptake efficiency relative to L159.
- Intervention effect In field trials H158 had higher yields across a gradient of nitrogen application rates.
- Intervention effect In field trials H158 had greater agronomic nitrogen use efficiency (ANUE) across a gradient of nitrogen application rates.
- Observation Genomic analysis identified 1,654 genes associated with NUE.
- Mechanism G/C variants of BjuB04 . NLP4 influenced transcriptional regulation and root-to-shoot ratio responses to nitrogen availability.
- Observation The BjuB04 . NLP4-HAP1 haplotype (L159) was more common in high-nitrogen soils.
- Method / resource The study provides elite germplasm and functional molecular markers for breeding rapeseed with enhanced NUE (author interpretation).
