Abstract excerpt

BACKGROUND AND AIMS: Phosphorus (P) deficiency severely limits rice productivity, yet the role of root developmental regulators in P homeostasis remains unclear. Here, we show that the rice PLETHORA transcription factor OsPLT1 suppresses rice tolerance to P-deficient conditions. Under P-starved conditions, osplt1 mutants accumulated more biomass and exhibited higher soluble and total P concentrations, whereas...
