How might the Cavendish varieties Be Saved From Extinction?
If successful, CRISPR techniques which confer TR4 resistance to the Cavendish could also be applied to domestic cultivars threatened by the fungus, providing greater food security to millions of people. It might even resurrect extinct banana species. “I hope we can bring back the Gros Michel,” says Tripathi wistfully.
Are bananas in danger of extinction?
Similar to humans, bananas are facing a pandemic. Nearly all of the bananas sold globally are just one kind called the Cavendish, which is susceptible to a deadly fungus called Tropical Race 4, or Panama Disease. If not stopped, Tropical Race 4 could wipe out the $25 billion banana industry.
What are scientists doing to prepare for the possible spread of Panama disease to the banana plantations of Latin America?
Researchers in Australia have found that adding two different genes to the genetic code of Cavendish bananas protects the plants from TR4. The first was taken from a wild banana resistant to TR4 and is one of a large family of genes that recognize invading diseases so that the plants can protect themselves.
Can the Cavendish banana be saved?
The most common banana variety is at risk of going extinct. But researchers have discovered a potential way to save it—and many other plants. The Cavendish accounts for about 99 percent of the world’s commercially produced bananas.
How do you preserve bananas?
6 easy hacks to keep bananas from ripening too fast
- Hang them, away from other produce.
- Wrap the stems in plastic wrap.
- Once they ripen, pop them in the fridge.
- If the bananas are peeled, add citrus.
- Give the bananas a vinegar bath.
- For longer periods of time, freeze.
How was the banana modified?
Most of the genetic modification methods commonly used in bananas were developed in the 1990s, including protoplast electroporation (Sági et al., 1994), particle bombardment (Sági et al., 1995), and Agrobacterium-mediated transformation (May et al., 1995).
How did bananas almost go extinct?
Here’s how it went down. In the 1950s, a strain of fungus fusarium wilt (aka Tropical Race 1), a strain of the fungal Panama Disease) spread throughout the Gros Michel population. The disease quickly distributed itself across banana plantations around the world.
Why are bananas becoming extinct?
Panama Disease Changes an Industry But problems with Panama disease, a fungus that causes the banana plant to wilt, showed up in the late 1800s and spread.
How do you control the wilt of bananas in Panama?
Intercropping and rotating banana (Musa spp.) with Chinese chive (Allium tuberosum Rottler) has been used as an effective method to control Panama disease (Fusarium wilt) of banana in South China.
What is the best way to avoid the banana bunchy top virus?
The most important factors in controlling banana bunchy top virus are killing the aphid vector (disease carrier) and rogueing (removing and destroying) infected ba- nana plants. By killing the aphids on the banana plant, dispersal of virus-carrying aphids to nearby, healthy ba- nana plants is avoided.
What will replace the Cavendish banana?
They replaced the Gros Michel banana (commonly known as Kampala banana in Kenya and Bogoya in Uganda) after it was devastated by Panama disease. They are unable to reproduce sexually, instead being propagated via identical clones….Cavendish banana.

How do you revive a banana plant?
Shake the soil from the roots and lay the plant on its side on top of a tarp or newspaper in your chosen location. Replant when all danger of frost has passed. You’ll want to give your tree plenty of water to revive it.
How do you prolong the life of a banana?
Why did bananas go extinct?
Why was the banana modified?
A field trial in Australia has shown that genetically modified banana trees can resist the deadly fungus that causes Panama disease, which has devastated banana crops in Asia, Africa, and Australia and is a major threat for banana growers in the Americas.
What are the benefits of genetically modified bananas?
Transgenic bananas appear to successfully resist a bacterial wilting disease and pest species that are devastating the critical food crop in tropical regions across the planet, according to a newly published scientific paper.
Will bananas survive?
Bananas on the brink. Facing this dire prognosis, can we bring bananas back from the brink? Well, it’s not really bananas, in general, that need saving. Several hundred varieties of this fruit thrive successfully around the world, and some are even resistant to fusarium wilt.
