PLPA 200 Lecture Notes - Lecture 10: Mycotoxin, Peanut Butter, Vomitoxin

Week 10 The Major Issue for this week is mycotoxins. So far you have learned that plant pathogens can affect our food supply by lowering crop yields or reducing food quality. In some cases, however, plant pathogens can ...

PLPA 200 Lecture Notes - Lecture 2: Mycelium, Cell Wall, Nuclear Membrane

Week 2 For a long time it was believed that fungi were specialized (or weird) versions of plants, because many of them grew out of the soil, and fungi don’t move around like animals do. Now we know that although fungi ha...

PLPA 200 Lecture Notes - Lecture 4: Root Rot, Sulfur Dioxide, Boron

Week 4 A Major Concept in plant pathology is that diseases can be caused by both living and non-living agents. Although we spend most of our time focused on plant diseases caused by living pathogenic organisms, many plan...
