Now you can design tubers with a more attractive color
The color of the peel of the potato is one of the main signs for consumers, which is often determining when choosing and buying.
In a new study, scientists at the James Hutton Institute identified a genetic molecule that regulates the production of anthocyanin, a natural pigment that in turn affects the skin color of potato tubers.
Researchers also identified previously unknown anthocyanin production inhibitors, which enabled potato breeders to use these genes in new breeding programs to create attractive color combinations.
“MicroRNA molecules regulate many potato genes and can detect traits, including disease resistance or tuberization. For the first time, we identified a specific potato microRNA closely related to the purple color of the peel and pulp. Using molecular biology methods, we characterized this microRNA and revealed the presence of another short RNA molecule in potatoes, which has not been previously described, ”the scientific work says,” the scientific work says.
This study shows the difficulty of creating a specific color in potato tubers and gives breeders an idea of the regulation of key attributes that influence consumer preferences.
The study was supported by the Scottish Government Environmental, Agriculture, and Food Strategic Research Program.
