Molecular Infection Medicine Sweden (MIMS), which is the Swedish's node in the Nordic EMBL Partnership for Molecular Medicine. The forest research includes plant and forest biotechnology within the Umeå Plant Science Centre (UPSC) – a collaborative effort between the Department of Plant Physiology at Umeå University and the Department of Forest Genetics and Plant Physiology at the Swedish University of Agricultural Sciences (SLU), and one of the strongest research environments for basic plant research in Europe, known for its research relating to the genome of the Populus tree and the Norway Spruce. The mapping of the spruce genome, in collaboration with the Swedish SciLifeLab, was the first complete sequencing of a gymnosperm and notable because it is seven times the size of the human genome, with some 20 billion base pairs.
