Other claims from this paper (7)
- Intervention effect Drought effects on nodule functionality were more pronounced with WT than cbb(3)(+) inoculation.
- Intervention effect cbb(3)(+) bacteroids had higher respiratory capacity than WT bacteroids regardless of plant treatment.
- Intervention effect cbb(3)(+) inoculation alleviated moderate drought effects on bacteroid respiration and nodule energy charge.
- Intervention effect FixP and FixO expression was higher in cbb(3)(+) than WT bacteroids under all conditions.
- Intervention effect Moderate drought caused a more pronounced decline in sucrose synthase activity with WT than cbb(3)(+) inoculation.
- Intervention effect Moderate drought caused a more pronounced decrease in nodule dicarboxylic acids with WT than cbb(3)(+) inoculation.
- Mechanism The authors interpret enhanced rhizobial cbb(3) expression as reducing symbiotic drought sensitivity and modulating nodule carbon metabolism.
