Virus resistance breaks down in Chinese GM papaya
Published: 07 August 2018
Ringspot virus-resistant GM papayas are often cited as a genetic engineering success. But a new study (abstract below) reports that in China, the virus resistance in GM papaya has broken down under pressure from a new lineage of the virus.
The study reports that the GM virus-resistant papaya planted in Hawaii retains its virus resistance. But this has not saved the Hawaiian papaya industry, since many countries don't want GM papaya and up to a third of the crop is thrown away because it's bruised or mis-shapen. As a result, USDA scientists have been looking at ways to make the unwanted GM papayas into biofuel.
In addition, a non-GM virus-resistant papaya has been developed, suggesting that the GM version is not needed.
