Chemical and Biological Mobilization of Soil Phosphorus by ppk-Expressing Transgenic Rice (Oryza sativa L.)

Phosphorus (P) availability in alkaline soils is constrained by the immobilization of legacy P, particularly through calcium phosphate precipitation. We used a confined soil–plant microcosm to examine how expression of the polyphosphate kinase gene (ppk) is associated with legacy...
