Potato toxin, α-solanine, was evolutionally diverged from a bitter-taste constituent of tomato

February 26, 2021

A research group including Kobe University, Kyoto University, RIKEN CSRS and Osaka University has clarified that a toxin containing in sprouts of potato, α-solanine, was diverged from bitter compounds such as α-tomatine in tomato.

The findings of this study may allow breeding that can control the biosynthesis of the toxic compoundin potato in the future.
