A model of Fe homeostasis regulation by MdCML15–MdBT2–MdbHLH104–MdAHA8 in apple trees. When apple roots are exposed to Fe-sufficient conditions, MdCML15 is induced to interact with MdBT2 in the nucleus to accelerate MdBT2-mediated ubiquitination and degradation of MdbHLH104, relieve transcriptional activation of MdAHA8, reduce H+ efflux, and thereby inhibit Fe absorption and prevent Fe toxicity.
