Other claims from this paper (17)
- Intervention effect The 75:25 mixture increased rice root biomass by 69.5% over 100:0.
- Intervention effect The 75:25 mixture increased tiller number by 42.5%.
- Intervention effect The 75:25 mixture increased yield by 46.8%.
- Intervention effect Rice root nitrogen content increased by 69.5%.
- Intervention effect Rice stem nitrogen content increased by 64.0%.
- Intervention effect Rice leaf nitrogen content increased by 65.5%.
- Intervention effect Rice grain nitrogen content increased by 17.5%.
- Observation NJXZ allocated a greater proportion of nitrogen to leaves and grains than MXZ2.
- Intervention effect The 75:25 mixture increased root glutamine synthetase activity by an average of 35.0%.
- Intervention effect The 75:25 mixture increased root glutamate synthetase activity by an average of 52.0%.
- Mechanism HISX and RPAB5 were inferred to regulate nitrogen-metabolizing enzyme activities.
- Mechanism SAT2, CYSKP, SYIM, CHI1, and XIP1 were inferred to modulate amino acid synthesis.
- Intervention effect The named genes had greater expression under the 75:25 mixture.
- Method / resource RT-qPCR confirmed the expression characteristics of the named genes.
- Association Expression levels of the named genes correlated significantly with glutamate synthase activity, photosynthetic rate, and root volume.
- Association Increased expression of the named genes accompanied nitrogen uptake in three main rice cultivars.
- Mechanism The authors infer that the 75:25 mixture promotes nitrogen uptake through upregulated nitrogen-metabolism genes and increased enzyme activity, contributing to more tillers and yield.
