Research Interests

We are interested in root hair development and differentiation. Starting with the genetic network of root hair growth, which enabled us to identify gene products of central importance, we continue to pursue several gene functions in detail whilst simultaneously using "top down" approaches to the network as a whole.

Current projects (with relevant students, research staff, and collaborators in brackets) include:

  1. The function and targets of the TIP1 S-acyl transferase (Piers Hemsley, Nick Davis, Paul Dupree, Kathryn Lilley, Shaul Yalovsky)
  2. Role and regulation of ROP small GTPases and their regulators in root hair growth (Matt Smallman, Eric Lalanne, Sarah Usher, Zhenbiao Yang)
  3. Regulation of root hair development by auxin (Angharad Jones, Colin Lazarus, Ottoline Leyser)
  4. Response of root development to the light environment (Fran Salisbury, Karen Halliday)
  5. Potential to model root hair development (Gordon Breen, Peter Green)
