Areas of research focus

  • Evolution of reproduction in an ancient group of seed plants, i.e. gymnosperms
  • Experimental embryogenesis of conifers
  • Cone and seed biology of lodgepole pine, Douglas-fir and larch
  • Host-parasite interactions during seed development
  • Pollination drop proteomics

von Aderkas’ research interests are focused on the evolution of plant reproduction by seed. This necessarily begins with study of the first pollen-ovule interactions.

In ancient seed plants, such as conifers and cycads, pollen is delivered by wind or animal and is then captured by the ovule’s pollination drop. By investigating chemical profiles of these drops, von Aderkas and students and post-docs in his lab have discovered the basis of a number of adaptations, such as defense systems and reward systems, i.e. nectar.

Recently, he has begun to work on flowering plant nectar. Most of the lab’s work is centered on conifers, as these trees are the mainstay of the forest industry in British Columbia.

The von Aderkas lab also studies conifer seed development, cone induction, cloning, population genetics, parasitism and disease.
