Arabidopsis bHLH100 and bHLH101 control iron homeostasis via a FIT-independent pathway.

PloS one - 1 Jan 2012

Sivitz Alicia B, Hermand Victor, Curie Catherine, Vert Grégory

Abstract excerpt

Iron deficiency induces a complex set of responses in plants, including developmental and physiological changes, to increase iron uptake from soil. In Arabidopsis, many transporters involved in the absorption and distribution of iron have been identified over the past decade. However, little is known about the signaling pathways and networks driving the various responses to low iron. Only the basic...
