RNA-seq of Arabidopsis spl7 identifies two genes required for copper acquisition and a copper dependence of iron homeostasis

ABSTRACT: The transition metal copper (Cu) is an essential element for all living organisms. In plants, Cu plays key roles in electron transport chains of chloroplasts and mitochondria, as well as in cell wall metabolism, ethylene perception, molybdenum cofactor synthesis and oxidative stress protection. Because of its physiological importance, suboptimal concentrations of Cu trigger a re-organization of metabolism to economize on Cu, and pronounced Cu deficiency causes severe growth reduction and defects in male fertility. However, when present in excess, Cu can be highly toxic. Therefore, Cu uptake, utilization and cellular concentrations are strictly regulated. A number of components of the Cu-homeostatic network of Arabidopsis have already been identified. However, the mechanisms that control re
