Yrjö Helariutta: Genetic control of wood development

We focus on genes that regulate various aspects of wood development. We study genes that contribute to cell division activity in vascular cambium, the meristem between xylem (wood) and phloem.

Understanding the regulation of the cambium activity enhancing factors might provide novel means to produce more biomass in trees. Also, we investigate genetics that regulate the morphogenesis of tree shoot system architecture.

We believe our research contributes to environmentally sound forest management, more efficient fruit and nut production, and aesthetics of common areas. To achieve our goals, we mainly use Populus trichocarpa and Betula pendula as model species.

Our main research interests are:

  1. Degree of apical dominance and branching
  2. Branch angle and orientation
  3. Wood and tension wood formation
