title: The development of infection structures by the rusts and other fungi.
abstract: Germlings of the rust fungi develop infection structures in response to specific cues from the host's surfaces. Features such as the stomatal guard cell, which directs placement of the appressorium over the stomate, serve to optimize pathogen entry. A wide range of plant parasitic fungi develop infection structures.
