About

Apoorva Bhatt - Research in 60 seconds videoGeorge Bassel was appointed as a Birmingham Fellow in 2012. His group focuses on understanding how genes change the shape of plant cells. Using seed germination as a model system, Dr. Bassel is uncovering gene regulatory networks that control cell shape changes, and how these networks are influenced be the environment.

Qualifications

PhD University of Guelph 2006 in Molecular and Cellular Biology
BSc University of Guelph 2001 in Biosciences 

Biography

George did a PhD on hormone signal transduction pathways in seeds with Dr. Derek Bewley FRSC at the University of Guelph, Canada. He went on to work as a postdoc with Dr. Nick Provart at the University of Toronto, and with Dr. Hiro Nonogaki at Oregon State University. Following three years of fellowship at the University of Nottingham with Prof. Michael Holdsworth, George was appointed as a Birmingham Fellow.

George is currently accepting applications for postgraduate students to look at the relationship between gene expression and changes in plant cell shape.

Research

The lab is using a multi-disciplinary approach to understand how genes control changes in the shape of plant cells. By examining post-embryonic growth of the model plant species Arabidopsis, we seek to uncover the molecular machinery that underlies the decision making process of a cell to commence expansion and the mechanisms that drive these shape changes.

Towards this, two complementary methodologies are being integrated:

1) Inference of co-functional Gene Networks (how genes influence other genes)

2) Quantitative analysis of 3D cellular geometric changes (how plant cells grow in 3D)

Functional gene interactions that modulate cell shape change have been computationally inferred from publicly available gene expression data in the lab. These predicted functional gene interactions are being investigated using quantitative high resolution imaging. In this way, the effects of these gene interactions can be quantified within the context of 3D cell shape changes.
