个人简介/ Biography：

Sheng Luan received his PhD from the Department of Cell and Developmental Biology and postdoc training in the Department of Chemistry at Harvard. He took a faculty position in the department of Plant and Microbial Biology at UC Berkeley as an assistant professor in 1994 and is now an endowed chair professor (Chancellor’s Professor). 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 2025. For community service, he was the associate chair and chair of his department from 2018-2024 and Executive Assoc. Dean (2025-). He was and has been the founding Editor-in-Chief of Molecular Plant, a leading journal in plant sciences.

报告摘要/ Summary：

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 and dissecting the Ca-CBL-CIPK signaling network that regulates nutrient sensing and homeostasis in plants.
