BTNY302 Plant Interactions

2021 information for papers will be published in early September. 

Positive and negative plant interactions with fungi, bacteria, viruses and animals, with an emphasis on how understanding plant interactions provides insights into plant biology from community structure to crop productivity.

Gain insight into how plants determine whether microbes and insects are friend or foe. Sophisticated mechanisms govern plant interactions and ultimately decide whether a plant will thrive or fail. Learn how these interactions impact on plant biotechnology, genetics, ecology and crop productivity.
