Salicylic acid (SA), an essential secondary messenger for plant defence responses, plays a role in maintaining a balance (trade-off) between plant growth and resistance induction, but the detailed mechanism has not been explored. Because the SA mimic benzothiadiazole (BTH) is a more stable inducer

UNASSIGNED This study identifies six UGT73Cs all able to glucosylate sapogenins at positions 3 and/or 28 which demonstrates that B. vulgaris has a much richer arsenal of UGTs involved in saponin biosynthesis than initially anticipated. The wild cruciferous plant Barbarea vulgaris is resistant to

Cultured plant cells of Eucalyptus perriniana glucosylated taxifolin to its 3'- and 7-O-beta-D-glucosides and 3',7-O-beta-D-diglucoside. On the other hand, taxifolin was converted into 3'- and 7-O-beta-D-glucosides by cultured cells of Nicotiana tabacum and Catharanthus roseus.

A pair of sesquiterpene glucosides, 3-hydroxysolavetivone-beta-D-glucoside A (1) and 3-hydroxysolavetivone-beta-D-glucoside B (2), have been isolated from the leaves of Nicotiana tabacum. The former is a new compound, while the latter is a known one. Their structures were established by

beta-Thujaplicin (hinokitiol) is a tropolone derivative present in the heartwood of cupressaceous plants and is used as a medicine, a food additive, and a preservative, and in cosmetics as hair tonic. The cultured plant cells of Nicotiana tabacum glycosylated beta-thujaplicin to two glucosides,

The fraction containing glycosidic components was separated from flue-cured tobacco (Nicotiana tabacum L.) leaves by a facile method. Some components of the fraction were isolated and elucidated to be syringin, coniferin, cichoriin, benzyl-beta-D-glucoside, Blumenol A-beta-D-glucoside, and

Tea possesses a distinctive flavor profile and can have health benefits owing to the high levels of flavonoids in its leaves. However, the mechanism of the flavonoid glycosylation hasn't been well studied in tea plants, especially glycosylation at the 7-OH site has rarely been reported. In this

ABSTRACT Salicylic acid (SA) is a key regulatory component of disease resistance in plants. In tobacco mosaic virus (TMV)-inoculated tobacco (Nicotiana tabacum cv. Xanthi-nc NN genotype), newly synthesized SA is converted primarily to SA 2-O-beta-D-glucoside (SAG) and glucosyl salicylate (GS), a
