  Ectopic Expression of Anthocyanin 5-O-Glucosyltransferase in Potato Tuber Causes Increased Resistance to Bacteria

  摘要：

  The principal goal of this paper was to investigate the significance of anthocyanin 5-O-glucosyltransferase (5-UGT) for potato tuber metabolism. The ectopic expression of a 5-UGT cDNA in the tuber improved the plant's defense against pathogen infection. The resistance of transgenic lines against Erwinia carotovora subsp. carotovora was about 2-fold higher than for nontransformed plants. In most cases the pathogen resistance was accompanied by a significant increase in tuber yield. To investigate the molecular basis of transgenic potato resistance, metabolic profiling of the plant was performed. In tuber extracts, the anthocyanin 3,5-O-substituted level was significantly increased when compared to that of the control plant. Of six anthocyanin compounds identified, the highest quantity for pelargonidin 3-rutinoside-5-glucoside acylated with p-coumaric acid and peonidin 3-rutinoside-5-glucoside acylated with p-coumaric acid was detected. A significant increase in starch and a decrease in sucrose level in transgenic tubers have been detected. The level of all other metabolites (amino acids, organic acids, polyamines, and fatty acids) was quite the same as in nontransformants. The plant resistance to bacterial infection correlates with anthocyanin content and sucrose level. The properties of recombinant glucosyltransferase were analyzed in in vitro experiments. The enzyme kinetics and its biochemical properties were similar to those from other sources.

  Separation and elucidation of anthocyanins in the fruit of mockstrawberry (Duchesnea indica Focke)

  摘要：

  Anthocyanin pigments in the fruit of mockstrawberry (Duchesnea indica Focke), were extracted with 0.1% HCl in ethanol, and the crude anthocyanin extract was purified by a C18 Sep-Pak cartridge open-column chromatography. High-performance liquid chromatography (HPLC) with photodiode array detection and mass spectrometry (MS) was applied for the isolation and composition analysis of anthocyanins in the fruit of mockstrawberry and their aglycones from acid hydrolysis. Three anthocyanins were found in the fruit of mockstrawberry and they were identified as cyanidin 3-O-rutinoside (61%), peonidin 3-O-rutinoside (34%), and petunidin 3-O-rutinoside (5%), respectively, by spectroscopic methods (UV-vis and MS). The two major anthocyanins were isolated by preparative HPLC, and their chemical structures were further characterised by H (1) NMR. On the basis of chromatographic data, the total anthocyanin content was 205 mg g(-1) of the fresh fruit of mockstrawberry.
