What Distinguishes Gene Editing From Genetic Engineering


Introduction:

Although the terms genetic engineering and gene editing may seem the same, authorities and scientists must make a distinction between the two.
 

From Conventional Breeding To The Wild:

It's crucial that we discuss traditional breeding practices first before delving into the distinctions between these two procedures. The crops that we grow today had a different set of traits when they were discovered in the wild. For instance, teosinte, a wild grass, is the source of corn. This natural grass has been domesticated over many years to better suit our needs for food, clothing, and energy. 
 
By choosing plants with improved features and including these plants in next crop improvement programs, plant breeders have employed ways to create new varieties of crops. One of the most well-liked techniques for doing this is known as hybrid seed technology, in which better seeds are created by mating two clearly different pure parental lines. Breeders don't produce seedlings with the required traits for several years, though. In order to achieve the desired results in less time, professionals have created more accurate approaches.
 

Traditional And Contemporary Biotechnology:

What Distinguishes Gene Editing From Genetic Engineering
Genetic engineering or genetic modification are the two terms most often used to describe contemporary crop enhancement approaches. With the help of this technique, a gene that codes for a certain trait can be introduced into an organism that requires it. For instance, it is possible to generate insect-resistant corn by transferring an insecticidal gene from a soil bacterium to corn plants. Without introducing a gene from another creature, a plant gene can be turned off or enhanced to improve a certain feature.
 
2019 saw the planting of genetically modified or biotech crops on 190.4 million hectares across 29 nations. It has been the crop technology that has been embraced most quickly in the history of modern agriculture because of its many advantages. 
 

Genetic Engineering Versus Gene Editing:

New breeding breakthroughs have been created as experts work to continuously improve crops for food security. Gene editing is the most recent agricultural science approach. In contrast to genetic engineering, it is a procedure for quickly, cheaply, and precisely altering a living organism's DNA.
 
Scientists frequently compare it to editing a word document on a computer. By locating a particular word or phrase, you can alter a section of that document. To make your paper better, you can either remove that term, swap it out with a stronger word, or add another word.
 
The most well-known technology to date is CRISPR-Cas9, which was modified by scientists from a natural gene-editing mechanism used by some bacteria to fight off invading diseases. There are also more tools like TALENs, zinc-finger nucleases, and mega nucleases. Gene editing has a wide range of uses due to its simplicity and adaptability, one of which is creating genetically modified (GM) crops. However, there are other additional ways to create GM crops.
 
In particular for regulations, the distinction between genetic engineering and gene editing is crucial. Before they are sold to the general public, genetic engineering products with a bit of foreign DNA must undergo a rigorous process. Gene-edited products must undergo the biosafety process before being released since they are viewed as GMOs in some nations. 
 
However, some nations take into account the presence of foreign DNA in the gene-edited product. Without a foreign DNA, the gene-edited crop is regarded as a by-product of traditional breeding and wouldn't require approval before being put on the market.
 
Calyno, a heart-healthy soybean oil, is one of the first products of gene editing. The researchers used TALENs to raise soybean oil's oleic acid content by 80% and decrease saturated fat by 20%. It has been offered since 2019 on the US market and has gotten positive reviews from the food sector.

Experts are adopting gene editing more and more in their studies, particularly to enhance the quality attributes of plants, which also has an impact on the world's food security.
