Cyanogenic seed defense featured in the News
The research of Carlos Mora and Jonas Halter about cyanogenic seed defence has been featured on several news platforms including ETH News.
Several layers of polylactic acid surround a wheat grain. An enzyme is embedded in the innermost layer, while the middle layers contain amygdalin. Insects can release these two substances as they feed, leading the enzyme to convert the amygdalin into hydrogen cyanide. This can weaken or kill the insect larvae. (Graphics: ETH Zurich)
