Synthesis of pterodontic acid derivatives and the study of their anti-influenza A virus (H1N1) activity.

Laggera pterodonta (DC.) Benth, a folk herb widely distributes in southwest China, especially in Yunnan Province, demonstrates anti-pathogenic microorganisms, anti-inflammatory, inhibition of Helicobacter pylori activities in vitro et al. Interestingly, previous studies have shown that pterodontic acid (1), a eudesmane-type sesquiterpene isolated from L.

Yellow nutsedge WRI4-like gene improves drought tolerance in Arabidopsis thaliana by promoting cuticular wax biosynthesis.

Background: Cuticular wax plays important role in protecting plants from drought stress. In Arabidopsis WRI4 improves drought tolerance by regulating the biosynthesis of fatty acids and cuticular wax. Cyperus esculentus (yellow nutsedge) is a tough weed found in tropical and temperate zones as well as in cooler regions.

Transcriptomic analysis of Eruca vesicaria subs. sativa lines with contrasting tolerance to polyethylene glycol-simulated drought stress.

Background: Eruca vesicaria subsp. sativa is one of the Cruciferae species most tolerant to drought stress. In our previous study some extremely drought-tolerant/sensitive Eruca lines were obtained.
