High impact information on Xanthium

  • We have investigated the molecular basis of imidazolinone tolerance of two field isolates of cocklebur (Xanthium sp.) from Mississippi and Missouri. In both cases, tolerance was conferred by a form of ALS that was less sensitive to inhibitors than the wild type [1].
  • Ethylene at 1.0 and 10.0 cubic centimeters per cubic meter decreased the rate of gravitropic bending in stems of cocklebur (Xanthium strumarium L.) and tomato (Lycopersicon esculentum Mill), but 0.1 cubic centimeter per cubic meter ethylene had little effect [2].
  • Acidic ethephon solutions applied to one side of young seedlings of cocklebur, tomato, sunflower (Helianthus annuus L.), and soybean (Glycine max [L.] Merr.) caused bending away from that side, but neutral ethephon solutions did not cause bending [2].
  • However, when Ca(2+) ions are present during polymerization, cocklebur morphologies are disrupted [3].
  • Two cytotoxic sesquiterpene lactones from the leaves of Xanthium strumarium and their in vitro inhibitory activity on farnesyltransferase [4].

Biological context of Xanthium

  • There were no statistically significant differences between Uni-Dur and Xanthium regarding bioavailability, Css(max), Css(av) as well as % FI [5].
  • Using single dose data for simulation of steady state pharmacokinetics, we found that a once-a-day dosage regimen with either Theo-24 or Xanthium would maintain serum levels within the therapeutic range for average non-smoking young adults whereas more frequent dosing intervals with Theo-Dur would be more appropriate [6].

Anatomical context of Xanthium

  • As an attempt to identify bioactive natural products with anti-inflammatory activity, we evaluated the effects of the methanol extract of the semen of Xanthium strumarium L [7].
