Banana with
delayed ripening trait is being developed by DNA Plant Technology Corporation
(US) similar to the technology used in the Endless Summer™ Tomato.
The technology is called Transwitch®. It involves the
insertion of an anti-sense copy of ACC synthase gene into the banana
plant thereby regulating the expression of the enzyme. This gene regulation
prevents the production of ethylene, the hormone that triggers the
ripening process of fruits. The advantage of using the anti-sense method
is that, no novel protein is generated in the plant.
