Innovative Cloning Technique Used Preserves DNA of Giant Tree and Paves the Way for Genetic Conservation

An impressive scientific discovery has just been made in Paraná! Researchers from Embrapa Florestas managed to clone a 700-year-old araucaria, the largest ever recorded in the state, which had been downed 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 achievement was grafting, which consists of joining a fragment of the original plant to a young seedling. Thus, the new tree retains exactly the same DNA as the original.

✅ Generated from 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

Where Were the Seedlings Planted?

The cloned seedlings have already been replanted in two special locations:

On the rural property where the original tree was, owned by Terezinha Wrubleski. She shares that the araucaria has been part of the family’s history for over 70 years and can now show its “daughter” to future generations.
At the Agricultural College of Cruz Machado, during a symbolic event with students, teachers, and local authorities.

Additionally, another seedling will be preserved in Embrapa’s genetic collection, while a fourth will be donated to the Government of the State of Paraná.

Why Is This Cloning So Important?

Genetic Conservation: The tree had unique DNA, and the study could reveal the secret of its resistance.
Accelerated Production of Pine Nuts: The new trees grow smaller, but the production of pine nuts is earlier than a conventional araucaria.
Environmental Preservation: This technology paves the way to save other century-old and threatened trees.

Why Is This Cloning So Important?

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

A Brazilian woman traveled 56 hours to China to train kung fu for three weeks at a school near the Shaolin Temple, facing up to six hours of daily exercises with the “iron body” technique that uses sticks to harden muscles, and went viral with over 4 million views.

Goodbye, Styrofoam? Entrepreneur creates recyclable cardboard cooler that keeps drinks cold for up to six hours and already sells 40,000 units per month. The product underwent 21 tests over nine months of development and entered the market with an investment of R$ 60,000.

The traffic sign with an arrow pointing down that confuses thousands of drivers may indicate an invisible risk on the road, and many people pass by it without understanding its true meaning.

Berlin opens a 25,000 m² hole in the center and unearths its medieval origins, with archaeologists racing against construction to save coins, latrines, shoes, ceramics, and bones of the first inhabitants before the site soon becomes urban apartments.

Mother and daughter left the city, became cheesemakers, and now sell sheep’s milk products in RS, according to a report, with award-winning sweets, their own agribusiness, and a demanding routine balancing motherhood, animals, climate, production, and sales in a niche market.
