Is there research or a startup working to genetically modify tropical fruit trees into a form that would be easier to cultivate in greenhouses. There doesn't seem to be any good reason why an avocado can't grow on a vine or even on a seaweed. Such fruit could be cheaper and higher quality as it would be local and could reach ripeness on the plant. And it will be less susceptible to anti-gmo activists, because unlike usual GMO that benefits growers, or benefits customers in a non-obvious way (like golden rice), it will benefit directly customers who will be getting delicious tropical fruit which now they can taste only when traveling.
