Saving Cavendish: Panama Disease-Resistant Bananas

Di: Ava

The first Australian approval for a genetically modified fruit has been granted to a Cavendish ­banana variety developed over the past 20 years that carries the hopes of saving the species from

Dale’s team has focused on altering Cavendish plants by inserting a gene from the wild banana Musa acuminate malaccensis that confers resistance to TR4. As the Gros Michel succumbed to Panama disease, the Cavendish banana emerged as its successor. While not immune, the Cavendish exhibited some resistance to the initial strain of the fungus.

Genetically modified bananas out to stop Cavendish catastrophe

Have you ever wondered why all bananas in supermarkets look alike and taste exactly the same? Because almost all exported bananas (Musa spp) are of a single cultivar, the Cavendish. Every single Cavendish is genetically identical; basically they are all clones! So what? Cavendish bananas are under a threat from a disease called Panama disease, also known as Fusarium

The bananas were given a resistance gene from either a wild relative or a nematode. Queensland University of Technology In 2012, the US-based Elo Life Systems, a biotech company targeting food sustainability, is tapping into gene-editing to save Cavendish bananas from a fungus that could potentially wipe out the species. Delve into banana history and the profound impact of diseases like Panama disease on plantations and global trade. This article examines the economic, social, and cultural consequences, the shift from Gros Michel to Cavendish varieties, and innovative strategies to combat threats like TR4. Discover the resilience of the banana industry and the future of

For more than 20 years, QUT researchers have been developing Cavendish bananas genetically modified to be resistant to Panama Disease TR4. The research has reached a significant milestone where a resistant line, called QCAV-4, has been developed. QUT researchers have developed and grown modified Cavendish bananas resistant to the devastating soil-borne fungus Fusarium wilt tropical race 4 (TR4), also known as Panama disease. Fusarium wilt of banana, popularly known as Panama disease, is a lethal fungal disease caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc). It is the first disease of bananas to have spread globally in the first half of the 20th century.

As a deadly disease spreads, the fight for a banana plantation in Mozambique might hold the key to saving the world’s favourite fruit.

Fusarium wilt is commonly known as Panama disease, the most devastating disease in the banana cultivation sector. It has destroyed banana plantations all over the world. Fusarium wilt (aka Panama Disease) tropical race 4 (TR4) is the greatest threat to the ongoing viability of the commercial Cavendish banana industry in many parts of the world, including Australia, and particularly the export industries based in Central and South America. RALEIGH, N.C. – Bananas are the world’s most popular fruit, but an untreatable fungus is threatening to destroy most of the world’s crop, according to the U.S. Department of Agriculture. Found in lunch boxes and snack bowls all over the world, the Cavendish banana is the most popular fruit and

Luckily, the banana companies realised that another variety of banana known as the “Cavendish”, unlike the “Gros Michel” type grown in Latin America at the time, was almost completely resistant to Panama disease. From the 1950s, plantations of Gros Michel (or “Big Mike”) were systematically cleared and replaced with Cavendish trees. The Cavendish had For decades the most-exported and therefore most important banana in the world was the Gros Michel, but in the 1950s it was practically wiped out by the fungus known as Panama disease or banana Abstract Before 1960, Panama disease (fusarium wilt) was the most important disease in the banana export trades. Although the importance of Panama disease decreased after the Cavendish cultivars replaced Gros Michel, recent outbreaks have renewed interest in

Regulatory appeal: A genetically modified, disease-resistant Cavendish banana plant could soon be commercially approved QUT researchers have developed and grown modified Cavendish bananas resistant to the devastating soil-borne fungus Fusarium wilt tropical race 4 (TR4), also known as Panama disease.

The banana you know and love — specifically, the Cavendish cultivar — faces a deadly threat. Fungal diseases are spreading across the globe, jeopardizing the future of this staple fruit. This Bananas, one of the world’s most beloved and widely consumed fruits, are facing a serious existential threat. The Cavendish banana, which makes up a significant portion of the global banana market, is under attack from a deadly fungal disease called Fusarium wilt, commonly known as Panama disease. This crisis is not just a matter of However, there may be hope. In an attempt to save the banana and the industry that produces it, scientists are in a race to create a new plant resistant to Panama disease.

The fight to save the world’s most popular sweet fruit from a devastating fungal disease has taken on a new dimension today, after food

As a deadly disease spreads, the fight for a banana plantation in Mozambique might hold the key to saving the world’s favourite fruit. Did you know that the bananas you eat today are not the same type as the ones people were eating a few generations ago? The banana you might have had with your breakfast today is a variety called the Cavendish banana, while the one that was in grocery stores up to the 1950s was a variety called Gros Michel, which was wiped out by a disease called Fusarium wilt

While resistant to the fungal disease that wiped out the Gros Michel banana in the 1950s, Cavendish monocultures remain vulnerable to emerging threats like the TR4 strain. Challenges and Considerations Disease Vulnerability: Susceptibility to Panama disease (TR4) threatens global production, with no
