Infection Process Stages: Pre Entry

Before a pathogen can penetrate a host tissue, a spore must germinate and grow on the surface of the plant. In the case of motile pathogens, they must find the host and negotiate its surface before entering the host. Some pathogens develop specialized penetration structures, such as aspersoria, while others utilise pre-existing openings in the plant's surface, such as wounds or stomatal pores. Plant viruses are often transported and introduced into the plant via vectors such as fungi or insects.
