A genetically modified Cavendish banana (specifically the QCAV-4 line) has been developed with high resistance to the devastating
Panama disease Tropical Race 4 (TR4) fungus. The resistance is achieved by inserting a specific gene, RGA2, derived from the wild banana Musa acuminata ssp. malaccensis, which helps the plant defend against the soil-borne wilt fungus.
Key details about the resistant gene and modification:
The Gene (RGA2): While the Cavendish already has the RGA2 gene, it is largely inactive or expressed at very low levels in conventional Cavendish bananas. The modified version (QCAV-4) uses a highly active version of this gene from a wild, resistant banana.
Effectiveness: Field trials showed that QCAV-4 was highly resistant to TR4, with only 2% of plants infected, compared to 66% in non-GM control plants.
Development: The modification was developed by researchers from the Queensland University of Technology (QUT).
Future Development: Researchers are also using CRISPR gene-editing technology in partnership with Fresh Del Monte to potentially activate the banana’s own existing RGA2 gene, rather than introducing one from a wild source.
Good, so the bland cavendish will never die and we actually learned something from the first mass-extinction event of more flavorful bananas. (the old more flavorful essence of the dead variety is still fckn. everywhere.)
