A3 (Shi) investigates the plasticity of cambium stem-cell activity to temperature and day length. Most plant biomass on earth is the immediate product of secondary thickening growth driven by the cambium. The environmental responsiveness of cambium stem cells is well documented and underlies the formation of pronounced annual rings in trees. This project will exploit the variation in plasticity of secondary thickening growth in A. thaliana hypocotyls and radish roots as a powerful models to identify the genetic and molecular basis of variation in cambium plasticity using quantitative genetics supplemented by single-cell transcriptomics.
