| Using somatic embryogenesis, researchers can grow many identical trees from a single tree seed embryo. |
A more recent advance at OFRI is the new somatic embryogenesis laboratory, set up in 2009. Somatic embryogenesis refers to generating masses of embryonic tissue from a single tree seed embryo or other plant tissue; these masses can then be stored frozen in liquid nitrogen for decades. From each of these masses, many (perhaps even thousands of) genetically identical trees can be produced.
Researchers are now using this lab to quickly and cost-effectively replicate trees with desirable genetics traits, such as hybrid white pines that can resist the deadly blister rust fungus and white spruce that have superior growth traits. In the future, this approach could be used to conserve the genetic diversity of tree species threatened by an exotic disease until a control strategy is found.
