Characterization of two key flavonoid 3-O-glycosyltransferases involved in the formation of flower color in Rhododendron delavayi.

Flower color, largely determined by anthocyanin, is one of the most important ornamental values of <i>Rhododendron delavayi</i>. However, scant information of anthocyanin biosynthesis has been reported in <i>R. delavayi</i>. We found that anthocyanidin 3-<i>O</i>-glycosides were the predominant anthocyanins detected in <i>R. delavayi</i> flowers accounting for 93.68-96.31% of the total anthocyanins during its development, which indicated the key role of flavonoid 3-<i>O</i>-glycosyltransferase (3GT) on <i>R. delavayi</i> flower color formation. Subsequently, based on correlation analysis between anthocyanins accumulation and <i>Rd3GTs</i> expressions during flower development, <i>Rd3GT1</i> and <i>Rd3GT6</i> were preliminarily identified as the pivotal <i>3GT</i> genes involved in the formation of color of <i>R. delavayi</i> flower. Tissue-specific expressions of <i>Rd3GT1</i> and <i>Rd3GT6</i> were examined, and their function as 3GT <i>in vivo</i> was confirmed through introducing into <i>Arabidopsis UGT78D2</i> mutant and <i>Nicotiana tabacum</i> plants. Furthermore, biochemical characterizations showed that both <i>Rd3GT1</i> and <i>Rd3GT6</i> could catalyze the addition of UDP-sugar to the 3-OH of anthocyanidin, and preferred UDP-Gal as their sugar donor and cyanidin as the most efficient substrate. This study not only provides insights into the biosynthesis of anthocyanin in <i>R. delavayi</i>, but also makes contribution to understand the mechanisms of its flower color formation. << Less

Purification and characterization of glycosyltransferases involved in anthocyanin biosynthesis in cell-suspension cultures of Daucus carota L.
Rose A., Glassgen W.E., Hopp W., Seitz H.U.
The major anthocyanins accumulated by an Afghan cultivar of Daucus carota L. are cyanidin 3-(xylosylglucosylgalactosides) acylated with sinapic or ferulic acid. The formation of the branched triglycoside present as a common structural element requires an ordered sequence of glycosylation events. T ... >> More
The major anthocyanins accumulated by an Afghan cultivar of Daucus carota L. are cyanidin 3-(xylosylglucosylgalactosides) acylated with sinapic or ferulic acid. The formation of the branched triglycoside present as a common structural element requires an ordered sequence of glycosylation events. Two of these enzymic glycosylation reactions have been detected in protein preparations from carrot cell-suspension cultures. The first step is a galactosyl transfer catalyzed by UDP-galactose: cyanidin galactosyltransferase (CGT) resulting in cyanidin 3-galactoside. The putative second step is the formation of cyanidin 3-(xylosylgalactoside) catalyzed by UDP-xylose: cyanidin 3-galactoside xylosyltransferase (CGXT). Both enzyme activities were characterized from crude protein preparations. The CGT was purified 526-fold from the cytosolic fraction of UV-irradiated cell cultures by ion-exchange chromatography on diethylaminoethyl (DEAE)-Sephacel, affinity chromatography on Blue Sepharose CL-6B, gel permeation chromatography on Sephadex G-75 and elution from the gel matrix after non-dissociating PAGE. Its molecular mass was estimated by SDS-PAGE and by calibrated gel permeation chromatography on Sephadex G-75. In both cases a molecular mass of 52 kDa was determined, indicating that the native protein is a monomer of 52 kDa. The galactosyl transfer and the xylosyl transfer are presumed to be catalyzed by separate enzymes. << Less
