HY5 orchestrates the transcriptional network controlling coumarin-mediated iron acquisition under elevated pH conditions
Iron (Fe) bioavailability is strongly limited in alkaline soils, where reduced Fe solubility severely restricts plant growth and productivity. To overcome this, Arabidopsis thaliana promotes Fe acquisition by secreting Fe-mobilizing coumarins, however, the transcriptional mechanisms coordinating this response is not cl...
