Research Interests:

My research group is investigating the role of calcium in signal transduction during plant development. A flexible confocal fluorescence ratio aiming assembly has been constructed and this is being used to image calcium redistribution during contact sensing, stomatal aperture control, pollen tube and rhizoid growth, moss development and photomorphogenesis. Plants have been transformed with the gene for the calcium sensitive luminescent protein aequorin generating a totally new method for measuring cytosolic calcium in plants and bacteria. Plants have also been transformed with genes for calmodulin to better assess the role of calcium in development. Projects are under way to clone plant calcium channels and MARCKS, an actin/calmodulin binding protein.
