Dr Sarah Robinson, Sainsbury Laboratory Cambridge University: The mechanics of plant development
Plants have diverse and interesting shapes. How they grow into these forms is a long-standing question in biology.
Plant growth is a physical process where the walls that the plant cells are embedded in, must soften to allow them to expand. The nature of this softening is controlled by the pattern of gene expression. As some regions soften and expand more than others, the shape of the tissue begins to change.
Dr Sarah Robinson’s lab team study the physical changes that occur during this growth using a small robotic device which enables precise forces to be applied to living plant tissues. This robot is attached to a confocal microscope so the team can visualise the gene expression in the cell at the same time as applying forces. This enables them to relate gene expression and cellular events with the changes in physical properties associated with growth.
