General description

Salicylic acid (SA) is a phenolic compound produced in plants.


Salicylic acid has been used:
  • to study its effects on glandular trichomes in Artemisia annua
  • to study its effects on DNA methylation in Taraxacum alatum andTaraxacum hemicyclum
  • to study its effects on parasite epidemics in Lolium arundinaceum

Biochem/physiol Actions

Salicylic acid (SA) plays a major role in the growth and development of plants. It also plays a role in endogenous signaling for plant disease resistance. SA is also involved in mediating thermogenesis and symptom development.

Glandular trichomes (GT) of Artemisia annua produce valuable compounds for pharmaceutical and industrial uses, most notably the anti-malarial artemisinin. Our aim was to find out whether the density, number and size of GT can be manipulated to advantage by environmental...

DNA methylation is one of the mechanisms underlying epigenetic modifications. DNA methylations can be environmentally induced and such induced modifications can at times be transmitted to successive generations. However, it remains speculative how common such environmentally induced transgenerational DNA methylation...

Acetylsalicylic acid (Aspirin) is rapidly metabolized to salicylic acid (salicylate) and other compounds, including gentisic acid and salicyluric acid. Monitoring of salicylate and its metabolites is of toxicological, pharmacological and biomedical interest. Three capillary electrophoresis (CE) methods featuring alkaline aqueous...
