Figure 4From: Expression of human dopamine receptor in potato (Solanum tuberosum) results in altered tuber carbon metabolismEnzyme activities. The activity of enzymes involved in sucrose and starch metabolism in tubers of control (D) and HD1 plants. Enzyme activities were measured in the same tuber's samples as the one used for carbohydrate, catecholamine and metabolite analysis. Data represent the mean ± SE of determination on three individual plants per line. Asterisks (*) indicate values that are significantly different from the wild type plants. SPS – sucrose phosphate synthase; UGPase – UDPglucose pyrophosphorylase; AGPase – ADPglucose pyrophosphorylase; SuSy – sucrose synthase, PGM – phosphoglucomutase; PGI – phosphoglucoisomerase; SS – starch synthaseBack to article page
