Dr. Sheng Luan, Professor, Department of Plant and Microbial Biology, UC Berkeley, will present the seminar “A kinase-phosphatase network for ion channel regulation in plants” on Tues., February 26, 2013 at 4:00 PM in N172 Beadle Center.

Bacteria and plants respond to environmental changes by modifying their membrane permeability (among other mechanisms). Environmental signals are transduced by molecular pathways that crosstalk to form a signaling network. Such signaling network involves activities of myriad protein kinases and phosphatases that in turn regulate the activities of membrane transporters such as ion channels through reversible protein phosphorylation and physical interaction. Regulation of membrane permeability and ionic homeostasis appear to be an ancient mechanism for surviving the constantly changing environment. The seminar will focus on a calcium-dependent signaling mechanism that can be widely applicable to the interpretation of other signaling processes in plants as well as in other organisms.
