Peronospora arabidis-hirsutae is an obligate plant pathogen causing downy mildew disease on Arabidopsis and related crucifers. It inhabits infected leaf tissue of host plants in temperate environments where Arabidopsis and related plants grow. This oomycete parasite spreads through asexual sporangia during wet conditions and forms persistent oospores in infected plant debris.

Peronospora conglomerata is an obligate biotrophic oomycete in the family Peronosporaceae, causing downy mildew disease on specific host plants. It forms branching sporangiophores that emerge through stomata to release sporangia dispersed by air currents. Like other downy mildews, it requires a specific host species and living tissue to complete its life cycle.
