How bacteria grow into specific, 3D shapes remains a central mystery in microbiology. My group has developed an imaging and analysis pipeline to simultaneously probe the shape of cells and the localization of proteins in 3D during growth. We find evidence for feedback between the local geometry of the cell, localization and orientation of key morphological polymers, and cell growth that sets rod shape and size in Escherichia coli cells.
