Reduction of Total Steroidal Glycoalkaloids in Potato Tubers Using Antisense Constructs of a Gene Encoding a Solanidine Glucosyl Transferase
Accumulation of steroidal glycoalkaloid (SGA) toxicants in potatoes affects food quality and safety. High levels of SGAs hamper breeding efforts to develop new varieties of potatoes with improved agronomic and post harvest properties. To speed breeding efforts for reducing SGAs in breeding lines and correcting flawed selections we are taking a molecular genetic approach to reduce SGAs. A cDNA e...
متن کاملPotato Glycoalkaloids, Past Present and Future
The steroidal glycoalkaloids are naturally occurring specialty metabolites of questionable desirability in the vegetable crop, potato. Although glycoalkaloids undoubtedly originated under selection as feeding deterrents against herbivorous pests, they no longer function as the primary feeding deterrent. Moreover, due to their potential toxicity, guidelines persist as to the maximal allowable co...
متن کاملRecovery of steroidal alkaloids from potato peels using pressurized liquid extraction.
A higher yield of glycoalkaloids was recovered from potato peels using pressurized liquid extraction (1.92 mg/g dried potato peels) compared to conventional solid-liquid extraction (0.981 mg/g dried potato peels). Response surface methodology deduced the optimal temperature and extracting solvent (methanol) for the pressurized liquid extraction (PLE) of glycoalkaloids as 80 °C in 89% methanol. ...
متن کاملGlycoalkaloids as biomarkers for recognition of cultivated, wild, and somatic hybrids of potato.
Cultivated and wild potato species synthesize a wide variety of steroidal glycoalkaloids (GAs). During breeding programs, species genomes are often put together through either sexual or somatic hybridization. Therefore, the determination of the GA composition of hybrids is very important in that it may affect either human consumption, or resistance to pathogen and pests. Here, we report the res...
متن کاملPotato- An Important Source of Nutritional Kynurenic Acid
Kynurenic acid (KYNA) is a metabolite of tryptophan which is formed along the kynurenine pathway. KYNA may possess neuroprotective, anti-inflammatory, antioxidant and antiproliferative properties. This study measured the concentration of KYNA in various varieties of potatoes and products made from potatoes. KYNA content was determined by means of the high-performance liquid chromatography with ...
