Research Area Biochemistry, cell and molecular biology of plant growth and development; auxin physiology and signal transduction; interactions between gravity, light and multiple hormones. Description of Research We are combining physiological, cellular, genetic and molecular techniques to study the steps along the transduction chain between perception of the plant growth hormone, auxin and response, both during development and in response to environmental stimuli such as gravity and light. Current studies include the positional cloning of the genes that are altered in tomato gravitropic and auxin response mutants. |
