POSITIVE REGULATOR OF IRON HOMEOSTASIS 1, OsPRI1, facilitates iron homeostasis ($)
Zhang et al. showed that POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 (OsPRI1), a bHLH transcription factor, is an interacting partner of the iron-binding sensor OsHRZ1. A loss-of-function mutation of OsPRI1 is responsible for a hypersensitive response to Fe deficiency. OsPRI1 works downstream of OsHRZ1 and directly controls the expression of OsIRO2 and OsIRO3 by binding […]
