Crop Genetics

Lars investigates the genetic and hormonal control over fruit shape development in the Brassicaceae.

Lars’ research uses Arabidopsis and its close relative Capsella, which produces flat heart-shaped fruit, with genomics technologies, mutant populations, optical projection tomography and modelling to understand the mechanisms which controls fruit shape.

Lars is interested in how fruit shape influences photosynthetic capacity and subsequently enhances seed yield, and how this knowledge can be transferred into crop species. 

  • Genetic regulation of fruit growth in Brassicas
  • The control of fruit shape and its effect on seed yield
  • Hormone perception in plants and the effect on organ development

 

The laboratory works primarily on genetic and hormonal regulation of fruit development in the Brassicaceae family (including Arabidopsis, oilseed rape and Capsella). The group is developing genetic resources for Brassica research and is using both molecular genetics and functional genomics to study fruit growth.

Members of the Brassica genus include important crop plants such as oilseed rape (Brassica napus). They belong to the Brassicaceae family such as the model plant Arabidopsis. The close evolutionary relationship between Brassica species and Arabidopsis is reflected in similar plant architecture and organ morphology. The similarities in for example fruit development suggest that the underlying patterning mechanism is conserved. 

In addition to the academic satisfaction of understanding biological processes, the knowledge acquired during studies of fruit development among Brassicaceae provides an enormous potential for knowledge transfer to improve crop performance.

Lars is focused on pursuing such translational opportunities and hence developing tools for crop improvement.
