α-Solanine and α-chaconine, steroidal glycoalkaloids (SGAs) found in potato (Solanum tuberosum), are among the best-known secondary metabolites in food crops. At low concentrations in potato tubers, SGAs are distasteful; however, at high concentrations, SGAs are harmful to humans and animals. Here, we show that POTATO GLYCOALKALOID BIOSYNTHESIS1 (PGA1) and PGA2, two genes that encode cytochrome...

As one of the world’s major agricultural crops, the cultivated potato (Sohum tuberosum L.) is consumed daily by millions of people from diverse cultural backgrounds. Potatoes are grown in -80% of all countries, and worldwide production stands in excess of 300 million tonnes per annum, a figure exceeded only by wheat, maize and rice’. Although the success of the potato as a starchy staple has be...

Only a small percentage of insect species are pests. However, pest species cause significant losses in agricultural and forest crops, and many are vectors of diseases. Currently, many scientists are focused on developing new tools to control insect populations, including secondary plant metabolites, e.g., alkaloids, glycoalkaloids, terpenoids, organic acids and alcohols, which show promise for ...

The accumulation of chlorophyll and antinutritional glycoalkaloids in potato tubers resulting from exposure to light has been widely recognized as a cause unpredictable quality loss tuber. While transcriptional regulation light-induced extensively investigated, the mechanisms post-transcriptional through miRNA remain largely unexplored. An experimental model, Solanum chacoense, were used identi...

Steroidal glycoalkaloids (SGAs), the nitrogen-containing compounds produced primarily by Liliaceae and Solanaceae species, are toxic to animals humans have putative roles in defense against pests. UDP-glycosyltransferases (UGTs) catalyze final glycosylation steps of SGA biosynthesis. Although previously published studies focused on effect UGT proteins biosynthesis, research understand effects c...

Composed of various native and non-native plants, the Brazilian flora in its biodiversity remains a potential food source. In this context, plant species known Brazil as unconventional plants (UFP) deserve to be highlighted. Moreover, information concerning safety consuming UFP their natural toxins is still scarce. Thus, we explore current literature (2010–2020) obtain on toxicity, toxins, unde...

Exposure to invasive weeds in pasturelands may result significant losses and toxicity forage crops. These species also contain a compound that be toxic as well beneficial depending upon the effect induced. The Ministry of Environment Republic Korea has now recognized Solanum carolinense (Horsenettle)—an weed species—as potential threat crops entire agro-ecosystem. As crop, Festuca arundinacea (...

metabolites found in many plants, such as potatoes. Glycoalkaloids are produced in leaves, roots, tubers and sprouts of the potato plant, and are involved in host plant resistance to bacteria, fungi, viruses, and insects. Several reports have showed that glycoalkaloids suppress the growth of cancer cells in human skin, liver, prostate, breast and colon. aChaconine, a trisaccharide glycoalkaloid...
