Reactive oxygen species (ROS) play an important role in root responses to potassium deprivation by regulating the expression of the high-affinity K(+) transporter gene AtHAK5 and other genes. Activation-tagged lines of Arabidopsis plants containing the AtHAK5 promoter driving luciferase were screened for bioluminescence under potassium-sufficient conditions. A member of the type III peroxidase family, RCI3, was isolated and when it was overexpressed by the activation tag, this led to the… CONTINUE READING
