Insulin in a plant seed

An edible plant seed could deliver your insulin or cancer drugs if David Craik’s research progresses as hoped. His team’s work at The University of Queensland’s Institute for Molecular Bioscience centres on cyclotides, which are a family of exceptionally stable circular proteins that occur naturally in many plants, such as violets and petunia.

Inspired by the stability and diversity of natural cyclotides, David’s team has developed a way to join the two ends of a linear protein, allowing them to create ‘designer’ cyclotides that can be incorporated into crop plants, turning them into production factories for therapeutic drugs and insecticides.
