Forest Molecular Genetics

The Forest Molecular Genetics (FMG) Programme focuses on the genetic control of growth and development in fast- growing plantation trees with a view to enhance biomass production and improve wood properties for timber, pulp, paper, and biomaterials production. Concomitant with this, we aim to understand molecular pest and disease resistance mechanisms in trees for yield protection and resilience. The programme is affiliated with the Forestry and Agricultural Biotechnology Institute (FABI), as well as the Genomics Research Institute (GRI) at UP. The FMG Leadership is also affiliated with the new Future Africa Institute at UP. We work in close collaboration with South African forestry companies through the FMG Consortium (FMGC) to develop capacity and resources for the application of tree biotechnology in operational tree improvement programmes.
