Dr. Sheng Luan, Professor and Chair Department of Plant & Microbial Biology, University of California, Berkeley

Sheng Luan received his PhD from the Department of Cell and Developmental Biology and postdoc training in the Department of Chemistry both at Harvard, followed by faculty position in the department of Plant and Microbial Biology at UC Berkeley. He is now a chancellor’s professor and the department chair. His work is focused on calcium signaling mechanisms in plants and has received several notable honors including AAAS Fellow, ASPB Fellow, Humboldt Research Award, and Charles Albert Shull Award (ASPB). He was a Web of Science “Highly Cited Researcher” from 2014 to 2023.

讲座摘要/Abstract:

Specificity in cell signaling is paramount to plant responses to specific environmental changes. Although calcium is a ubiquitous messenger in plant responses to numerous signals, the mechanism of signal-response specificity remains unclear. Studies in the past four decades in both animal and plant cell models have established the "calcium signature" concept that depicts a distinct calcium change in response to each specific signal. How is a calcium signature encoded by calcium transporters and channels working together and decoded by calcium sensors and their targets represent exciting but challenging questions in the field. Luan lab has been working on both encoding and decoding mechanisms for the past 25 years. They made several breakthroughs on calcium encoding mechanisms, including identification of calcium channels responsible for calcium spiking in pollen tube growth, pollen tube reception, and immune responses. They also pioneered the studies on “decoding” process by identifying the Ca-CBL-CIPK signaling network that regulates nutrient sensing and homeostasis in plants. Dr. Luan will summarize these research findings to provide a conceptual framework on calcium signaling mechanisms.
