Tweaking Carotenoid Genes Helps Tomatoes Bring Their A-Game
Published:02 Dec.2020    Source:University of Tsukuba

Researchers led by the University of Tsukuba demonstrated that Target-AID gene editing technology can be used to simultaneously introduce single-base changes into multiple genes in tomatoes. Using this technique, the researchers altered three genes associated with carotenoid accumulation, resulting in elevated levels of carotenoids, particularly lycopene, in the resulting tomato lines. This technology will allow tomato breeders to introduce multiple advantageous gene changes into elite commercial cultivars, bypassing lengthy back-crossing steps between generations.

 
Cooked, fresh, sun-dried, or juiced, whichever way you prefer them, tomatoes are arguably one of the most versatile fruits on the planet -- and yes, despite mainly being used in savory dishes, tomatoes really are a fruit.
