Serendipita indica enhances rice phosphorus uptake by 164% under low-P conditions through OsA1-stimulated root hair growth.
- Why it matters: Improving phosphorus acquisition is critical for rice productivity, especially under P deficiency, but the role of plasma membrane H+-ATPase OsA1 in this process was unclear.
- What they did: The study involved inoculating rice seedlings with S. indica under low-P conditions and measuring shoot and root P concentrations, root hair length, OsA1 expression, H+ efflux, and ATPase activity, comparing wild-type and mutant rice.
- The result: S. indica increased shoot P by 90%, root P by 164%, and root hair length, with OsA1 expression up by 73.2%, and enhanced H+ efflux and ATPase activity in wild-type rice, but not in mutants, indicating OsA1's key role in P uptake.
