Using the pathogens tricks to gain resistance

Plants and pathogens are involved in a tug of war. A lot of that fight takes place in the extracellular space, the space between cells, in plant tissues. There plants secrete an arsenal of defence molecules, like proteases, glycosidases and lipases. Pathogens do this as well including some inhibitors. So how come those inhibitors don’t inhibit the pathogen’s own arsenal?

Parasite plants give their development a headstart

For their nutrients are parasitic plants dependent on their host plant. Logically they make sure to time their germination accordingly. Up till now the assumption was that parasitic plants only develop an haustorium when they perceive specific haustorium inducing signals from their host. Now a new study shows that that is not the whole story.
