Difference between light- and wound-induced biosynthesis of α-solanine and α-chaconine in potato tubers

Brief communications


Potato tuber tissues can incorporate mevalonic acid-2-14C into glycoalkaloids, namely α-chaconine and α-solanine. The percent incorporation of this labeled precursor into α-chaconine in light exposed tubers is more than that of mechanically injured tubers.
