A consortium of scientists from the United States, China and Europe has published the complete genome of the domesticated¹ watermelon—one of the top five consumed fresh fruits—in the journal Nature Genetics. 

 

The group compared the genomes of 20 different watermelons across three different subspecies and found it takes roughly the same number of genes³ to make the sweet summer fruits as it does to make us.

 

They researchers also found that, in the process of being selected for color, size and taste, domestic watermelon lost many of the genes that helped their wild ancestors resist disease. They hope that breeders can now use the genetic² info to recover some of those natural disease defenses—as well as bringing a more nutritious⁴, and tastier fruit to your table. Without the seeds, of course.
