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?

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

SpaceX will dock a $843 million vehicle to the International Space Station to push a nearly 420-ton laboratory against the atmosphere and make the debris fall in a controlled manner into the ocean.

Seven friends went to test metal detectors in a waterlogged field and found 2,584 silver coins buried almost 1,000 years ago: treasure valued at R$ 31 million includes pieces from William the Conqueror and Harold II and has become the most valuable discovery in England’s history.

Luciano Hang, owner of Havan, becomes a model entrepreneur in Brazil, but the harsh reality is rarely told: each new megastore requires up to R$ 100 million, takes about 5 years to break even, and can generate R$ 14 million annually per unit.

In a historic decision, Aneel regulates the use of batteries in the Brazilian electrical system and lays the groundwork for large-scale energy storage, reducing waste, enhancing energy security, and attracting new billion-dollar projects.

A 65,000-kilometer scar hidden at the bottom of the ocean reveals how the Earth continues to slowly open up as scientists observe the gigantic underwater ridge that has been reshaping continents for millions of years.
