Scientists Are Using Gene Editing To Create the Perfect Tomato For Your Salad (qz.com)

An anonymous reader shares an article: Geneticists are now using technology to isolate the precise genes responsible for excessive branching and flowering, characteristics which lead to less fruit and thus less yield for farmers. In a study published in the journal Cell last week, geneticist Zachary Lippman of Cold Spring Harbor Laboratory explains his research team's efforts to fix mutated tomatoes using CRISPR gene editing technology. By identifying the genes associated with undesired mutations, Lippman was able to edit them and suppress their effects. After playing with the plant architecture, Lippman's team was ultimately able to engineer highly productive plants that yielded more of the desired fruit and less of the unwanted flowers and branches.

    Commercial tomatoes are no better in Europe. In both places, the only ripe commercial tomatoes are in cans or roadside stands.

    The stories about Monsanto suing innocent farmers are myths or more complicated than some narratives portray them. Popular Monsanto myths have been debunked over and over, yet they keep being brought up:

    Yeah, I was hoping to read how they created the most delicious tomato possible. I guess that's harder than just increasing yields.

    Efficient mass production, not flavor and nutritional content, are the goals of this research. The focus is more tomatoes per acre and higher yields on the grocer's shelf. Obviously the resulting tomato replica has to look like a tomato, act like a tomato, taste kinda like a tomato and be more-or-less non-toxic. If it fails the last 2 criteria we'll see if marketing spin it. The tomato, like the consumer, is a product to be manipulated for the profitability of the corporation.

    Tomatoes are harvested green and shipped. They don't develop the sugars that make them sweet because they're not ripened on the vine. Were they vine-ripened, shipping them to remote states would land you with rotting tomatoes.

    In practice, tomato flavor is related to the distance shipped from the harvesting operation. The logistics to get tomatoes to your table with less time between picking and purchasing are responsible for providing better flavor.
