Scientists are now able to accelerate the development of plant varieties for high productivity urban farming.
The genetic engineering (by gene editing) of such plants is focused on faster maturity, compact, dense and short plants, and higher yield.
We are already seeing that some urban agriculture companies are able to deliver 300X more productivity in vertical farms as compared to traditional farms. And that is with plant varieties that are not genetically engineered to deliver more.
Here is an article that gives us the example of tomatoes engineered for urban agriculture.
