Make way for the ‘super spud’! British scientists are altering the DNA of potatoes so they cook as fast as pasta

Experts plan to use the famous gene editing tool CRISPR, which acts like 'molecular scissors' that can cut the two strands of DNA at a specific location

They are a versatile dinner option and are full of fiber.

But waiting for the humble potato to cook must be one of the frustrating experiences for any home chef.

Fortunately, those days could soon be over, as British scientists are working on a “super potato” that cooks as quickly as pasta and rice.

Using gene editing, scientists plan to make adjustments to the part of the potato’s DNA that controls how quickly the plant’s cells soften.

Experts hope that gene-edited potatoes will be grown commercially before ending up on supermarket shelves.

Sales of potatoes in Britain are falling because consumers want carbohydrates that cook much faster, such as rice and pasta.

The new project is led by Lincoln-based agritech company B-hive Innovations, alongside Branston Potatoes and Scotland’s James Hutton Institute.

According to the partners, potato sales in Britain are falling because consumers want carbohydrates that cook much faster, such as rice and pasta.

A key focus will be the Maris Piper potato, known for its pale golden skin and creamy white flesh, considered an “all-rounder” because it is good for making chips, roasts and more.

The project, codenamed TuberGene, will also address another major problem for potato growers: bruising.

Around five million tonnes of potatoes are produced in the UK each year, but a large number do not meet commercial specifications, causing food waste.

“The UK potato industry faces significant challenges and it is vital that we find innovative solutions to ensure its long-term viability,” said Dr Andy Gill, CEO of B-hive Innovations.

“This project represents an important step forward in our efforts to address issues such as bruise-related losses and changing consumer preferences.”

What are gene-edited crops?

Gene editing promises to produce “super crops” by altering or deleting genes found naturally in plants.

Unlike genetically modified (GM) plants, genetically edited (GE) crops do not contain “foreign” DNA from other species.

GM crops are produced using CRISPR, a new tool for making precise edits to DNA.

Scientists use a specialized protein to make small changes to the plant’s DNA that could occur naturally or through selective breeding.

GM crops have had foreign genes added to their DNA, a process that often cannot occur naturally.

Making small changes to a specific gene location within potato DNA can introduce desirable traits that would otherwise take years to develop.

In addition to potatoes cooking faster and being less likely to bruise, these changes could also include greater disease resistance, better nutritional value, or a longer shelf life.

Experts plan to use the famous gene editing tool CRISPR, which acts like “molecular scissors” that can cut the two strands of DNA at a specific location.

“Gene editing and other precision breeding technologies offer unprecedented opportunities to rapidly improve potato traits, meeting the need to respond quickly to changing consumer preferences,” said Dr. Rob Hancock, research scientist at the Institute. James Hutton.

“By focusing on specific genes responsible for traits such as bruising susceptibility and cooking times, we can create varieties that meet the needs of both producers and consumers.”

It follows new legislation passed by the UK government in 2023 allowing the commercial development of gene-edited crops.

Environment Secretary George Eustice has previously insisted that GM products would not need to be advertised as such because they are “fundamentally natural”.

However, gene-edited foods remain controversial because, according to some critics, there is no record of their safe and reliable use.

Although they are two terms that are often confused, genetic editing (GE) is different from genetic modification (GM).

GM is the process of changing the DNA of an organism, such as a bacteria, plant or animal, by introducing DNA elements from a different organism.

Meanwhile, transgenic involves changing an organism’s DNA through alterations to its genetic code, without any “foreign” DNA from other species.

According to the Food Standards Agency, genetically modified foods are only authorized for sale in the UK if they are considered to pose no health risk or mislead consumers.

Additionally, if GM foods have less nutritional value than their non-GM counterparts, they will not be allowed to be sold.

Concerns over gene editing in agriculture

The RSPCA has published a list of issues related to removing the gene editing (GE) ban:

· There is no history of safe and reliable use

· Genetic technologies can cause unpredictable and involuntary changes in the genome

· Not enough is known about the medium and long-term effects on animal health and welfare.

· Current GMO rules and regulations remain essential to regulate GMOs until there is more evidence of their use; Now is not the time to consider changing them.

· Alternative approaches exist to achieve the proposed benefits of genetic technologies, for example reducing food waste (12 percent of all meat and animal products produced globally is lost or wasted each year) and improving animal husbandry. animals.

· Approval of GM products has been withdrawn in the US due to regulator concerns about the transfer of other genes during the GM process.

· GM produced foods could reach supermarket shelves in Scotland and Wales despite those countries opposing their production and sale.
