Our laboratory develops tools for reprogramming gene expression and visualising cell dynamics in growing plants. These can be used to reprogram morphogenesis and metabolism. We have chosen Marchantia polymorpha as a simple model system for understanding and engineering plant growth. This lower plant provides unparalleled benefits in ease of culture, simple genome, haploid genetics, open form of development and rapid growth and regeneration, and is an ideal partner for modern quantitative analytical tools.
