Kiwifruit Duplicated Its Vitamin C Genes Twice
Wednesday, 2018/10/03 | 08:16:57

Today's kiwifruit contains about as much vitamin C as an orange. Its genome revealed that this extra boost in vitamin C is the result of the fruit's ancestors' spontaneously duplicating their DNA in two separate evolutionary events approximately 50-57 million and 18-20 million years ago.

 

The kiwifruit genome has been affected by polyploidization events, and to find out traces of these vents, the researchers compared the kiwi genome to the well-characterized coffee and grape genomes. Kiwis, coffee, and grapes share a common ancestor and thus share large swaths of genetic information. They found that the kiwi's genome often contained four or five copies of a gene in places where the coffee or grape had only one. The kiwi's extra genes included the biological instructions for creating and recycling vitamin C.

 

Vitamin C is not only for healthy for people, but also for plant growth and resistance to damage. The kiwifruit's superior vitamin C production gave it a leg up in the evolutionary game. In contrast, the coffee bean's advantage was probably its ability to produce caffeine, a natural pesticide that can also kill neighboring plant competition, whereas the chemical producing the grape's purple pigment most likely evolved to protect the plant from extreme temperatures.
