16 May 2019 --- Scientists at the Agricultural Research Service (ARS) and the Boyce Thompson Institute (BTWI) have completed mapping the pan-genome (the entire gene set of all strains of a species) for the cultivated tomato and its wild relatives. In the process, they have identified almost 5,000 previously undocumented genes. With the availability of this vast array of specific genetic information, the researchers say breeders should be able to increase the flavor of store bought, mass-produced tomatoes while preserving the traits that make them an economically advantageous crop.
