Alkaloid Biosynthesis and Transport

Uncovering the chemical secrets of plants

Plants are the world’s greenest chemists. Powered by solar energy, they produce a variety of natural products with medicinal and industrial applications. However, the precise manner in which plants produce and mobilize many of these compounds remains unknown. Our group combines a solid background in chemistry with state-of-the-art technologies in a quest to uncover the chemical secrets of plants, with special focus on alkaloids. Biotechnological applications include the production of medicinal compounds in cost-effective systems and the removal of anti-nutritional compounds from promising crops.




  • Alkaloid biosynthesis. Alkaloids are a class of natural products that have had an enormous impact on the quality of human life. Their impressive range of bioactivities has led to utilization as pharmaceuticals, stimulants, and pesticides (e.g. morphine, caffeine, nicotine). Our group specializes in the discovery of plant enzymes involved in the conversion of simple metabolic building blocks into complex alkaloid structures.
  • Alkaloid transport. Very often, plant alkaloids are accumulated in tissues that are different from the ones that produce them. Our group investigates the long-distance networks translocating alkaloids from biosynthesis sites to storage sites, with emphasis on the discovery of transporter proteins.
    • Synthetic biology. We use our discoveries to devise strategies for the cost-effective production of medicinal alkaloids in production hosts such as yeast or the model plant Nicotiana benthamiana. In cases where toxic alkaloids accumulate in promising crop plants, we use novel breeding technologies to remove the toxic alkaloids from the edible parts of the plant in a selective manner.
    • MicroProteins. We’re currently hosting members of the former research group of Professor Stephan Wenkel, now at Umeå Plant Science Center. The group studies the role of microProteins in plant development and adaptation in both model and crop plants. Current group members:
      • Alexandra Miotti, MSc student
      • Ashleigh Katrina Edwards, PhD student
      • Giacomo Matera, ERASMUS student
      • Louise Petri, PhD student
      • Maurizio Junior Chiurazzi, PhD student 
      • Ylenia Vitozzi, PhD student

    For students wishing to work within these topics, M.Sc. and B.Sc. projects are currently available. Please contact
