A novel hydroxycinnamoyl transferase for synthesis of hydroxycinnamoyl spermine conjugates in plants.

Background: Hydroxycinnamoyl-spermine conjugates (HCSpm) are a class of hydroxycinnamic acid amides (HCAAs), which not only are instrumental in plant development and stress response, but also benefit human health. However, HCSpm are not commonly produced in plants, and the mechanism of their biosynthesis remains unclear. In previous investigations of phenolics in Solanum fruits related to eggplant (Solanum melongena L.

Enhanced Expression of Pullulanase in by New Strong Promoters Mined From Transcriptome Data, Both Alone and in Combination.

Pullulanase plays an important role as a starch hydrolysis enzyme in the production of bio-fuels and animal feed, and in the food industry. Compared to the methods currently used for pullulanase production, synthesis by would be safer and easier. However, the current yield of pullulanase from is low to meet industrial requirements.

Characterization of spermidine hydroxycinnamoyl transferases from eggplant ( L.) and its wild relative Dunal.

Eggplant produces a variety of hydroxycinnamic acid amides (HCAAs) that have an important role in plant development and adaptation to environmental changes. In this study, we identified and characterized a spermidine hydroxycinnamoyl transferase (SHT) from eggplant () and its wild relative , designated as and , respectively. was abundant in flowers and fruits, whereas the level of was remarkably low in all tissues.
