Arabidopsis harbors four UDP-glycosyltransferases that convert hydroxycinnamates (HCAs) to 1-O-beta-glucose esters, UGT84A1 (encoded by At4g15480), UGT84A2 (At3g21560), UGT84A3 (At4g15490), and UGT84A4 (At4g15500). To elucidate the role of the individual UGT84A enzymes in planta we analyzed gene
In oilseed rape (Brassica napus), the glucosyltransferase UGT84A9 catalyzes the formation of 1-O-sinapoyl-beta-glucose, which feeds as acyl donor into a broad range of accumulating sinapate esters, including the major antinutritive seed component sinapoylcholine (sinapine). Since down-regulation of
Laminarin, a beta-1,3 glucan with single beta-glucose branches at position 6, was chemically sulfated to produce PS3 with a degree of sulfation of 2.4. PS3 has previously been shown to activate the salicylic acid (SA) signaling pathway in infiltrated tobacco and Arabidopsis thaliana leaf tissues.
