Research

PI-portraits-xu-jian2My research interests lie in the understanding of how a multicellular organism can grow and develop from a single cell and how the appropriate cell types are specified in the right place in an organism. I aim to gain a deep insight into the basic principles of cell polarity and pattern formation during plant development, using root systems of two model plants: the eudicot plant Arabidopsis thaliana (Arabidopsis) and the monocot crop Oryza sativa (Rice).

Research Projects

  • Environmental and developmental regulation of root architecture in plants
  • Cellular and molecular mechanisms of regeneration in plants
  • Polar auxin transport and pattern formation in plants
