Research in our lab focusses on the cell biological processes underpinning Streptomyces sporulation, the master regulators that control these processes, and the regulatory networks that link the two.
Our approach exploits a broad range of disciplines including cell biology, modelling, global ‘omics’ methods, genetics and biochemistry, right through to X-ray crystallography. As part of our work, we have recently pioneered the development of Streptomyces venezuelae as a new model system for the genus. Unlike most Streptomyces species, S. venezuelae sporulates in liquid culture, giving us a unique opportunity to follow the movement of multiple developmental proteins in time and space during differentiation using time-lapse imaging (movies). Sporulation in liquid culture also allows us to optimally apply global approaches like microarray transcriptional profiling and ChIP-seq to the analysis of cellular differentiation.
In addition to our developmental research, we also investigate the molecular mechanisms that mediate oxidative and cell envelope stress responses in Streptomyces, and those involved in the control of antibiotic resistance, focussing on key components of each signal transduction pathway.
