PSC Distinguished Seminar series
Title 1: Transport system of mineral elements in rice
Speaker: Prof. Jian Feng Ma, Institute of Plant Science and Resources, Okayama University, Japan
Time: 9:30 am
Day/Date: July 15th, 2019 (Monday)
Host: Prof. Chao-Feng Huang
Venue: PSC Auditorium
 
Abstract:
Plants require 14 mineral elements for their growth and development.  Transport of these mineral elements from soil to different organs and tissues requires various different transporters.  During last decade, a number of transporters for mineral elements have been identified in different plant species. In my talk, I will present our work on mineral element transporters identified in rice, especially focusing on silicon (Si).  Si is a beneficial element for plant growth and its high accumulation is required for high and sustainable production of rice, which is a typical Si-accumulating species.  We have identified four different transporters for uptake, xylem loading and distribution of Si in rice.  Furthermore, we performed mathematical modelling on Si transport and found that other factors such as apoplastic barrier and enlargement of the nodes are also important for efficient uptake and distribution of Si in rice.
 
 
Title 2: Phosphatidic acid signaling in plants
Speaker: Prof. Wenhua Zhang, College of Life Sciences, Nanjing Agricultural University
Time: 10:30 am
Day/Date: July 15th, 2019 (Monday)
Host: Prof. Chao-Feng Huang
Venue: PSC Auditorium
 
Abstract:
Phosphatidic acid (PA) serves as a precursor for the synthesis of glycerol-phospholipids and triacylglycerol. In addition, PA functions as an important signaling lipid involved in regulating various fundamental cellular functions. PA function in signal transduction in response to various environmental and internal cues is finished by its direct interaction with effector proteins, such as protein kinases, phosphatases, phospholipases, transcription factors, NADPH oxidases, and microtubule-associated proteins. Such an interaction usually modulates effector’s localization and activity. In this presentation, I will talk about PA-protein interaction and their functions in stress responses. I will also outline the methods for PA determination.
 
The seminar will be delivered in English.
