Steroidal glycoalkaloids in Solanum chacoense.
Potato (Solanum tuberosum L.), a domesticated species that is the fourth most important world agricultural commodity, requires significant management to minimize the effects of herbivore and pathogen damage on crop yield. A wild relative, Solanum chacoense Bitt., has been of interest to plant breeders because it produces an abundance of novel steroidal glycoalkaloid compounds, leptines and lept...
متن کاملSterol side chain reductase 2 is a key enzyme in the biosynthesis of cholesterol, the common precursor of toxic steroidal glycoalkaloids in potato.
Potatoes (Solanum tuberosum) contain α-solanine and α-chaconine, two well-known toxic steroidal glycoalkaloids (SGAs). Sprouts and green tubers accumulate especially high levels of SGAs. Although SGAs were proposed to be biosynthesized from cholesterol, the biosynthetic pathway for plant cholesterol is poorly understood. Here, we identify sterol side chain reductase 2 (SSR2) from potato as a ke...
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 کاملReduction 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 کاملSteroidal Glycoalkaloids and Molluscicidal Activity of Solanum asperum Rich. Fruits
Solanum L. (Solanaceae) is distributed mainly throughout the tropical and subtropical regions of the world and is the largest and most complex genus of the family Solanaceae. In Brazil, Solanum is represented by about 350 species. In this region, many species of Solanum are widely used in popular medicine and are commonly known as ‘yubeba’, the word derived from Tupi Guarani that refers to the ...
