Tastier tomatoes may soon be available in the market after a team of scientists from different countries has successfully analyzed the genome of the fruit, making it possible to produce tomatoes with richer flavor. 
Scientists in the
  past worked on lengthening the shelf-life
  of tomatoes to prevent tomatoes from quickly ripening. Since then, many
  varieties of tomatoes with long shelf-lives have been produced and marketed. 
However, long shelf-life
  has compromised the color and
  flavor of the tomatoes. Since ripening is slowed down, the tomatoes’ color
  and flavor do not completely develop, and they no longer look or taste as
  good as home-grown tomatoes. 
Now that the
  scientists have analyzed the tomato genome, they can work on finding which
  specific genes dictate only the
  flavor and color of the tomato.  They can
  then produce a variety of tomatoes that can last for a long time but is full
  of phytochemicals, has a dark red color and has richer taste. 
With information
  about the genome now available, scientists and tomato producers can also use traditional
  breeding techniques to produce precise results more quickly. 
These techniques
  are different from genetic modification. Scientists tried making a genetically modified
  tomato called “Flavr Savr” in the 1990s. Although it was considered safe to
  eat, the public worried about the effect of genetic modification. The product
  did not last long on the market. 
The new, more
  flavorful varieties of tomatoes, on the other hand, are expected to have major
  impact in the global tomato industry, which is worth of $30 to $40 billion
  yearly.
