主講人簡介：

Staffan Persson completed his PhD in Dec, 2003, which was a joint degree between Lund University (Sweden) and North Carolina State University (US). He then pursued a postdoc at the Carnegie Institution of Washington at Stanford University 2004-2007. Staffan was appointed as a Max-Planck Group Leader at the MPI for Molecular Plant Physiology in Potsdam in 2008, where he stayed until 2014. Since Jan 2015 Staffan is a R@MAP Professor and an ARC Future Fellow (level 3) at the School of BioSciences at University of Melbourne. He is a Thomson Reuter/Web of Science highly cited researcher 2016 and 2017. The research in his group aims at understanding how plants are producing cellulose, which is the most abundant biopolymer on Earth and that is a raw material for many applications in our society.  For further information see: http://blogs.unimelb.edu.au/persson-lab/

講座簡介：

The actin cytoskeleton is essential for organisms to grow and develop as it supports cell shape, motility and division. In plant cells, the actin cytoskeleton is important for distribution of organelles, pattering of cell wall polymers, and drives cytoplasmic streaming. To better understand the actin cytoskeleton, it is important to quantify its features. However, such framework has remained difficult to implement and the system-level properties of actin-based cellular trafficking therefore remain largely unknown. We have developed an automated image-based, network-driven framework to accurately segment and quantify actin cytoskeletal structures and organelle transport. We could show that the actin cytoskeleton in both growing and elongated hypocotyl plant cells has structural properties facilitating efficient transport. We utilized this framework to explore actin features during cotton fiber growth and to quantify changes in the actin cytoskeleton that supports stem gravitropism in rice. Thus, our framework provides quantitative assessments of the actin cytoskeleton to investigate its properties in living cells. Notably, this framework can be used to estimate cytoskeletal organization and transport in all types of organisms.
