Innovative cloning technique used to preserve giant tree's DNA paves way for genetic conservation
One of the impressive scientific discovery has just been held in Paraná! Researchers from Embrapa Forests managed to clone one 700 year old araucaria, the largest ever recorded in the state, which was cut down for a time. The pioneering project resulted in the production of genetically identical seedlings, ensuring the preservation of this natural heritage, according to the Itatiaia website.
How was the cloning done?
The method used for this historic feat was grafting, which consists of joining a fragment of the original plant to a young seedling. Thus, the new tree maintains exactly the same DNA as the original.
✅ Were generated by the trunk of the fallen araucaria
✅ These fragments were grafted onto healthy seedlings
✅ The new plants grew with the same characteristics as the mother tree

The researcher Ivar Wendling, from Embrapa, explains that the procedure was requested, since such old trees have low regeneration capacity. “Rescuing such an old araucaria and successfully cloning it is a scientific achievement,” he celebrates.
Where were the seedlings planted?
The cloned seedlings have already been replanted in two special places:
- Na rural property where the original tree was, belonging to Terezinha Wrubleski. She says that the araucaria was part of the family's history for over 70 years and now she will be able to show her “daughter” to future generations.
- No Cruz Machado Agricultural College, in a symbolic event with students, teachers and local authorities.
In addition, another seedling will be preserved in Embrapa's genetic collection, while a fourth will be donated to Paraná State Government.
Why is this cloning so important?
- Genetic conservation: The tree had unique DNA, and the study could reveal the secret of its resistance.
- Accelerated pine nut production: New trees grow less, but pine nut production it's earlier than a conventional araucaria.
- environmental preservation: This technology paves the way to save other ancient and endangered trees.
