Hey, our ancestors made two changes when selecting tomatoes over an extended time frame. In doing so, they created those big tasty beasts we have today.
A recent study, which builds on the first tomato genome sequence completed just two years ago, shows in great detail how the processes of early domestication and modern breeding influenced the genetic makeup of cultivated tomatoes.
Analysis of the genome sequences of 360 modern varieties, plus a number of wild strains shows which regions of the genome were under selection during domestication and breeding.
The study identified two independent sets of genes responsible for making the fruit of modern commercial tomatoes 100 times larger,
---- than their wild ancestors!
