 Plants have natural interactions with bacteria, fungi, nematodes, and possibly parasitic plants (stariga, casccuta etc).  They may be inoculated with viruses during feeding by insects or by other vectors (insects/pest, water, air, humans etc).  Plant pathogens have made many adaptations to enable them to invade plants, overcome plant defense mechanisms, and colonize plant tissues for growth, survival, and reproduction. plant tissues for growth, survival, and reproduction.  Pathogens accomplish these activities mostly through secretions of chemical substances that affect certain components or metabolic mechanisms of their hosts.  Penetration and invasion, however, seem to be aided by or in some cases be entirely the result of, the mechanical force exerted by certain pathogens on the cell walls of the plant.
