SgPHR1-SgPAE1 module modulates root growth and increases low phosphorus tolerance in Stylosanthes guianensis.
Phosphorus (P) deficiency severely limits agricultural productivity in tropical acid soils. Stylosanthes guianensis (stylo), a vital forage legume in the tropics, exhibits high tolerance to low P stress. While numerous phosphate (Pi) starvation response genes have been documented in stylo, its underlying regulatory mec...
