SRF3-bHLH Crosstalk in Arabidopsis Iron Homeostasis: Receptor Kinase Signaling, Transcriptional Regulation and Genetic Epistasis
In this review, the available evidence that connects the SRF3 receptor kinase with the bHLH-driven Fe-deficiency regulatory network in Arabidopsis plants is summarized. The data currently available suggests that SRF3 and bHLH-mediated regulation are functionally convergent in the regulation of IRT1, but there is curren...
