Potato steroidal glycoalkaloid levels and the expression of key isoprenoid metabolic genes.

Planta - 1 Dec 2007

Krits Pinchas, Fogelman Edna, Ginzberg Idit

Abstract excerpt

The potato steroidal glycoalkaloids (SGA) are toxic secondary metabolites, and their total content in tubers should not exceed 20 mg/100 g fresh weight. The two major SGA in cultivated potato (Solanum tuberosum) are alpha-chaconine and alpha-solanine. SGA biosynthetic genes and the genetic factors that control their expression have not yet been determined. In the present study, potato genotypes exhibiting...
