Meals Scientists Are Growing a "Tremendous Potato" to Save the World

As the worldwide menace of local weather change continues to jeopardize sustainable meals provides, a brand new initiative led by scientists from McGill College in Montreal, QC is ready to probably change the way forward for potatoes. 

Professor Martina Strömvik and her staff have unveiled a cutting-edge “tremendous potato” pangenome geared toward figuring out genetic traits that might usher within the period of the subsequent tremendous spud.

“Our tremendous pangenome sheds mild on the potato’s genetic variety and what sorts of genetic traits might probably be bred into our modern-day crop to make it higher,” Strömvik stated in an announcement. 


“It represents 60 species and is probably the most intensive assortment of genome sequence knowledge for the potato and its kin thus far,” Strömvik provides.

A genome, sometimes called an organism’s full set of genetic directions, is the muse of this venture. A pangenome seeks to embody the complete genetic variety inside a species, whereas an excellent pangenome ambitiously incorporates a number of species.

Local weather-adaptive potatoes

The common-or-garden potato is a dietary staple for billions worldwide and performs a pivotal function within the world meals provide, rating solely behind rice and wheat by way of human consumption. Many specialists agree that plant-based meals are pivotal in decreasing food-related greenhouse fuel emissions and adapting to extra sustainable consuming practices. 

And if a “tremendous potato” is developed that’s climate-adaptive and extra nutritious, it could be an enormous step ahead in enhancing the world’s meals safety. 

“Wild potato species can educate us quite a bit about what genetic traits are essential in adapting to local weather change and excessive climate, enhancing dietary high quality, and enhancing meals safety,” Strömvik says.

To assemble the potato pangenome, the analysis staff harnessed the facility of supercomputers, meticulously analyzing knowledge from public knowledge banks, together with gene banks in Canada, the USA, and Peru.

In line with the researchers, the pangenome has the potential to reply profound questions concerning the evolution of this very important crop, which was domesticated by Indigenous peoples within the mountains of southern Peru practically 10,000 years in the past. It might additionally function a priceless useful resource in figuring out particular genes for creating an excellent spud by means of conventional breeding strategies or superior gene enhancing expertise.


“Scientists hope to develop one thing that may defend in opposition to numerous types of illnesses and higher face up to excessive climate like extreme rain, frost, or drought,” Strömvik emphasizes.

Can potatoes save the world?

The disclosing of the potato tremendous pangenome represents a monumental leap ahead within the quest for climate-resilient and nutritionally enhanced potatoes, providing a glimmer of hope for making certain sustainable meals provides in an more and more difficult world. 

“Potatoes are an necessary meals crop for people for a number of causes, particularly vitamin,” Noah Praamsma, MS, RDN, Vitamin Training Coordinator for the Physicians Committee for Accountable Medication, tells VegNews.

Regardless of generally being seen as a meals to keep away from, potatoes are literally a terrific supply of carbohydrates. “Carbohydrates come within the type of starch, which releases vitality at a gradual price and is nice for intestine well being, in addition to fiber, which helps hold you feeling full and helps coronary heart well being,” Praamsma says.


“Potatoes additionally comprise many micronutrients, like vitamin C and potassium. Candy potatoes are wealthy in vitamin A and nice for eye and immune system well being, and potatoes that come in several colours (like purple potatoes) are particularly excessive in antioxidants,” Praamsma provides.

Along with their dietary worth, potatoes may also be grown nearly wherever and may be saved for a number of months after being harvested. 

In earlier years, the potato has already been genetically modified to make them simpler for us to develop and eat. But when they’re already so nice, why make them higher?

“These small modifications will assist extra potatoes keep good to promote and eat, decreasing meals waste, and can stop carcinogens from forming when potatoes are cooked at excessive warmth,” Praamsma  says.

“Different genetic modifications might make potatoes nonetheless extra nutritious than they already are,” Praamsma provides. 

Praamsma factors to earlier many years, when scientists developed a rice breed that accommodates vitamin A. “Golden rice was an enormous win for the billion or so folks worldwide who eat quite a lot of rice and that suffer from vitamin A deficiency, and related modifications to potatoes may very well be in our future.”
