Summary

Firm adhesion of fungal plant pathogens to their hosts is critical at several stages in the host-parasite interaction. Spores of many fungal species are capable of rapid, non-specific attachment to various surfaces. This early adhesion, which often occurs well before germ tube emergence, prevents spores from being blown or washed from the host surface before infection can take place. Adhesion is critical for proper sensing of topographic signals involved in thigmotropic responses and for differentiation and function of appressoria. Four fungal pathogens which exhibit a variety of adhesion mechanisms have been selected for discussion.
