Abstract:
α-Solanine and α-chaconine are the major glycoalkaloids (SGAs) in potatoes, but up to now the biosynthesis of these saponins is not fully understood. In planta13CO2 labeling experiments monitored by nuclear magnetic resonance spectroscopy (NMR) and high-resolution mass spectrometry (HRMS) unraveled the SGA biosynthetic pathways from CO2 photosynthates via early precursors to the SGAs. After a pulse of ~ 700 ppm 13CO2 for four hours, followed by a chase period for seven days, specific 13C-distrib...     »
