Abstract: The present invention relates to key genes in the biosynthesis of steroidal alkaloids and saponins, including regulatory genes and enzyme-encoding genes, and to use thereof for altering the content of steroidal (glyco)alkaloids or phytosterols in plants. The present invention provides genetically modified plants or gene edited plants with altered content of steroidal (glyco)alkaloids, particularly to Solanaceous crop plants with reduced content of antinutritional steroidal glycoalkaloids and to the increase in phytosterols, including cholesterol or cholestanol in these plants. The present invention also provides methods of altering gene expression.

Abstract: Provided herein are genetically modified cells and genetically modified plants having increased or decreased expression of a cellulose synthase like G (CSLG) enzyme. These cells and plants may have an increased or decreased content a steroidal alkaloid, a steroidal saponin, or a triterpenoid saponin, compared to a corresponding unmodified cell or plant. Also provided herein are methods of producing a steroidal alkaloid, a steroidal saponin, or a triterpenoid saponin in a genetically modified cell, as well as methods of reducing the content of a steroidal alkaloid, a steroidal saponin, or a triterpenoid saponin in a cell of a plant or a plant part, and methods of increasing the content of a steroidal alkaloid, a steroidal saponin, or a triterpenoid saponin in a cell of a plant or a plant part.

Abstract: Disclosed herein are genetically modified plants having altered biological activity of 3-?-hydroxysteroid dehydrogenase/isomerase (GAME25), or 2-oxoglutarate-dependent dioxygenase (GAME31), or a combination thereof, wherein the genetically modified plants have an altered content of at least one cholesterol derived compound selected from the group including a steroidal alkaloid or a glycosylated derivative thereof and an unsaturated or saturated steroidal saponin or a glycoside derivative thereof. Further disclosed herein are genetically modified plants having altered expression of a gene encoding a 3-?-hydroxysteroid dehydrogenase/isomerase (GAME25), or a 2-oxoglutarate-dependent dioxygenase (GAME31), or a combination thereof, wherein the genetically modified plant has an altered content of at least one cholesterol derived compound selected from the group including a steroidal alkaloid or a glycosylated derivative thereof and an unsaturated or saturated steroidal saponin or a glycoside derivative thereof.
