  There is already a cavendish variety that resists the fungus or what is it attacking it, but it was created using gene manipulation so it’s not allowed in the EU

    Can we do a plague resistant Gros Michel, please?

    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).
    • Approval: In February 2024, the Australian government approved this genetically modified banana for commercial release.
    • 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.)

  Let’s just hope they have a bunch of seeds cryogenically frozen in a lab somewhere.

    There is no such thing as a banana seed. All banana types are singular lineages of clones. All bananas of a certain type (currently cavendish is the one exported to all around the world) are the same genetically, that’s why they are so susceptible to colony-destroying fungal infections.

      There absolutely is. The commercial bananas just had seeds bread out of them

        When talking about the preservation of the Cavendish Banana what they said is relevant.
