The governor of Guárico state, Donald Donaire, signed an alliance to create a Seed Bank, which will be crucial for the upcoming winter season. The partners in this initiative are the Dr. Humberto Fernández Moran Agricultural Biotechnology Center, located in Caracas, and the Ministry of Science and Technology.

The objective of this Seed Bank is “the recovery and conservation of seeds, as well as the country’s agricultural diversity, all in response to the genetic erosion caused by foreign agricultural practices.”

According to Donaire, this Bank will guarantee producers access to “quality genetic material, adapted to the local environment, thus ensuring the supply of food both regionally and nationally.”

It will also be a tool for safeguarding inputs for the South American country’s agri-food sector.

The genetic disorder known as Down syndrome has been the subject of a study by researchers at Mei University in Japan, who have made progress in the study of chromosome 21 and its elimination.

As is known, Down syndrome “is a genetic disorder caused by the presence of an extra copy of chromosome 21, a phenomenon known as trisomy 21, which causes physical and cognitive alterations in those who suffer from it, such as heart defects, hearing loss, and difficulties in speech and learning development.”

At Mei University, scientists have applied a gene editing technique that could allow the complete elimination of the extra chromosome.

According to the PNAS Nexus publication, the scientists used “a tool called CRISPR-Cas9 to eliminate excess chromosomes in affected cells and return cell behavior to its normal function.”

This action aids in gene editing, which uses an enzyme to identify specific DNA sequences. “Once the enzyme finds a matching site, it selectively removes the extra copy of chromosome 21. This process, called allele-specific editing, allows the cutting enzyme to act only on the trisomy without affecting the rest of the genetic material.”

As a result, the group of scientists observed that gene expression normalized. Furthermore, the corrected cells accelerated their growth, with a shorter doubling time.

The discovery is a remarkable step toward controlling chromosome 21, which causes Down syndrome worldwide.
