Abstract
There has been a great deal of recent progress in our understanding of the genetic control of root hair development, particularly in Arabidopsis thaliana. This chapter summarizes the genes and gene products that have been identified using forward and reverse genetic approaches. The involvement of these genes at various stages of root hair development is described, including the specification of the root hair cell type, the initiation of the root hair outgrowth, and the elongation (tip growth) of the root hair.
