Abstract
Clover (Trifolium spp.) rhizobia enter their host’s roots through the root hairs. Infection is preceded by a deformation of root hairs and the forming of an infection thread that can be observed directly under the microscope. Root hair deformations may also be caused by nonnodulating strains of Rhizobium. Nonnodulating strains used in this chapter cause no infection threads to form. The purpose of this chapter is to observe the infection of legume roots by rhizobia. Clover seedlings are inoculated with rhizobia and stages of the infection process are then observed under the microscope.
