The Evil Genius Of The Brassica Genus: An Investigation Of The Chemical Cross-Talk Between Aspergillus Nidulans And Non-Host Seeds, Emma Smith
WWU Honors College Senior Projects
Aspergillus is a widespread saprophytic fungus that contaminates important grain and seed crops postharvest. Many different plants within the Brassicaceae family, and within the Brassica genus more specifically, are known to produce a variety of antimicrobial volatile defense chemicals. Three Brassica plants- Arabidopsis thaliana, Novantina (cultivar of Brassica rapa), and Tatsoi (cultivar of Brassica rapa)- were incubated with Aspergillus nidulans spores in an experimental test chamber. The test chambers were created by fitting together two GMM agar plates and sealing them with microporous surgical tape, so headspace gases were shared between the plates but gaseous exchange with the ambient environment …
