The potential of cannabinoids to address public health challenges has stimulated exploration into alternative sources and production technologies. Radula marginata, an endemic Aotearoa/New Zealand liverwort, produces the bibenzyl cannabinoid perrottetinene (PET), analogous to Cannabis psychoactive tetrahydrocannabinol (THC). Structural differences between PET and THC could alter therapeutic interactions and mitigate adverse side effects.

- Blueberries have a variety of anthocyanins that give them their blue color, and some types can produce more stable acylated anthocyanins, making them a focus for breeding.
- This study focused on a specific gene, VcAAT1a, which was found to effectively produce different acylated anthocyanins in various plant systems.
- The research identified that VcAAT1a only uses acetyl CoA as an acyl donor, and its promoter is activated by certain transcription factors, providing insight into how anthocyanin production is regulated in blueberries.
Dihydrochalcones (DHCs) are flavonoids produced as a side branch of the phenylpropanoid pathway. DHCs are found at high concentrations in apples (Malus spp.) but not in pears (Pyrus spp.

- The study identifies two key genes, BGLU13.1 and PPO05, involved in the breakdown of dihydrochalcones (DHCs) in apples, which are important flavonoids for plant defense.
- BGLU13.1 hydrolyzes phlorizin to produce phloretin, while PPO05 further oxidizes it; in wild Malus, it mainly oxidizes trilobatin instead.
- The research shows that the catabolism pathways of DHCs enhance apple resistance to certain pests and pathogens, indicating different pathways may be more effective against specific types of biotic stress.
Insects rely on the detection of chemical cues present in the environment to guide their foraging and reproductive behaviour. As such, insects have evolved a sophisticated chemical processing system in their antennae comprised of several types of olfactory proteins. Of these proteins, odorant degrading enzymes are responsible for metabolising the chemical cues within the antennae, thereby maintaining olfactory system function.
