Functional Descriptions:

  • Furthermore, unlike OsPHR2-overexpressing lines, which exhibited growth retardation under normal or Pi-deficient conditions, OsPHR3-overexpressing plants exhibited significant tolerance to low Pi stress but normal growth rates under normal Pi conditions, suggesting that OsPHR3 would be useful for molecular breeding to improve Pi uptake/use efficiency under phosphate-deficient conditions.
  • We propose that OsPHR1, OsPHR2 and OsPHR3 form a network and play diverse roles in regulating Pi signaling and homeostasis in rice.
  • OsPHR3 affects the traits governing nitrogen homeostasis in rice.
  • During vegetative growth phase, compared with the wild-type, OsPHR3 mutants showed significant variations in the adventitious root development, influx rates of 15N-NO3- and 15N-NH4+, concentrations of total N, NO3- and NH4+ in different tissues, and the relative expression levels of OsNRT1.
  • The effects of the mutation in OsPHR3 was also explicit on the seed-set and grain yield during growth in a pot soil.
  • Here the role of OsPHR3 was examined in regulating the homeostasis of N under different Pi regimes.
  • OsPHR3 plays a pivotal role in regulating the homeostasis of N independent of Pi availability.
  • Overexpression of OsPHR3 improves growth traits and facilitates nitrogen use efficiency under low phosphate condition.
  • Furthermore, overexpression of OsPHR3 increased N use efficiency, 1000-grain weight and grain yield under different Pi conditions.
  • The overexpression of OsPHR3 increased N uptake under Pi stress regimes.
  • ), OsPHR3 is one of the four paralogs of PHR1, which acts as a central regulator of phosphate (Pi) homeostasis, as well being involved in N homeostasis.
  • However, the functions of OsPHR3 in N utilization under different Pi conditions have yet to be fully studied.
