Examples of oomycete in the following topics:

• Chromalveolata: Stramenopiles

  • Stramenophiles include photosynthetic marine algae and heterotrophic protists such as diatoms, brown and golden algae, and oomycetes.
  • As diploid spores, many oomycetes have two oppositely-directed flagella (one hairy and one smooth) for locomotion.
  • The oomycetes are non-photosynthetic and include many saprobes and parasites.
  • Most oomycetes are aquatic, but some parasitize terrestrial plants.
  • Describe characteristics of the following Stramenophiles:  diatoms, brown algae, golden algae, and oomycetes

• Protists as Plant Pathogens

  • The oomycete Plasmopara viticola parasitizes grape plants, which causes a disease called downy mildew .
  • Phytophthora infestans is an oomycete responsible for potato late blight.
