Pyrethrins are natural insecticides, which accumulate to high concentrations in pyrethrum (Chrysanthemum cinerariaefolium) flowers. Synthetic pyrethroids are more stable, more efficacious and cheaper, but contemporary requirements for safe and environmentally friendly pesticides encourage a return

Arabidopsis thaliana contains a large number of genes encoding carboxylic acid-activating enzymes, including long-chain fatty acyl-CoA synthetase (LACS), 4-coumarate:CoA ligases (4CL), and proteins closely related to 4CLs with unknown activities. The function of these 4CL-like proteins was

A valuable strategy to improve crop yield consists in the use of plant growth-promoting rhizobacteria (PGPRs). However, the influence of PGPR colonization on plant physiology is largely unknown. PGPR Burkholderia phytofirmans strain PsJN (Bp PsJN) colonized only Arabidopsis thaliana roots after seed

The final steps of jasmonic acid (JA) biosynthesis are thought to involve peroxisomal beta-oxidation, but this has not been directly demonstrated. The last and key step in fatty acid beta-oxidation is catalyzed by 3-ketoacyl-CoA thiolase (KAT) (EC 2.3.1.16). A mutant of Arabidopsis thaliana ecotype

Jasmonates (JAs) are fatty acid derivatives that mediate many developmental processes and stress responses in plants. Synthetic jasmonate derivatives (commonly isotopically labeled), which mimic the action of the endogenous compounds are often employed as internal standards or probes to study

In addition to OPR1 and OPR2, two isoenzymes of 12-oxophytodienoate reductase, a third isoform (OPR3) has recently been identified in Arabidopsis thaliana (L.) Heynh. The expression of the OPR3 gene is induced not only by a variety of stimuli, such as touch, wind, wounding, UV-light and application

Enzyme 12-oxophytodienoate (OPDA) reductase (EC1.3.1.42), which is involved in the biosynthesis of jasmonic acid (JA), catalyses the reduction of 10, 11-double bonds of OPDA to yield 3-oxo-2-(2'-pentenyl)-cyclopentane-1-octanoic acid (OPC-8:0). The rice OsOPR1 gene encodes OPDA reductase (OPR)
