Other claims from this paper (12)
- Intervention effect Increasing phosphorus supply increased nodule weight, nitrogenase activity and ureide content in dual-root soybean on the phosphorus-application side.
- Intervention effect Increasing phosphorus supply increased the number of bacteroids and infected cells in soybean nodules on the phosphorus-application side.
- Intervention effect Increasing phosphorus supply increased relative expression of nodule nitrogen fixation key genes in root nodules on the phosphorus-application side.
- Association Phosphorus-induced increases were more prominent on the phosphorus-application side than on the phosphorus-free side in soybean.
- Association The authors conclude that phosphorus supply systematically regulates nodulation and nitrogen fixation in soybean.
- Intervention effect Raising phosphorus supply from 1 to 31 mg/L increased nodule phosphorus content by 57.14–85.71% and 68.75–75.00%, respectively.
- Intervention effect Raising phosphorus supply from 1 to 31 mg/L increased ARA by 218.64–383.33%.
- Intervention effect Raising phosphorus supply from 1 to 31 mg/L increased SNA by 11.41–16.11%.
- Intervention effect Raising phosphorus supply from 1 to 31 mg/L increased ureide content by 118.18–156.44%.
- Intervention effect Raising phosphorus supply from 31 to 61 mg/L gave a smaller gain in root and nodule phosphorus content, ARA, SNA and ureide content than the 1 to 31 mg/L step, and a lower value for nodules.
- Intervention effect A high phosphorus supply on one side of dual-root soybean significantly increased phosphorus content in the aboveground tissues, roots and nodules on both sides.
- Mechanism The authors interpret that nodules on the phosphorus-free side are prioritized for phosphorus from the aboveground tissues to maintain their phosphorus content and functionality.
