The function of the oxylipin 12-oxophytodienoic acid in cell signaling, stress acclimation, and development.

The properties of OPDA that are linked to the activities of PGs, which are derived from arachidonic acid and act as tissue hormones in animals, including humans are described.

Jasmonates: News on Occurrence, Biosynthesis, Metabolism and Action of an Ancient Group of Signaling Compounds

Jasmonic acid-induced gene expressions in the numerous biotic and abiotic stress responses and development are initiated in a well-studied complex regulation by homeostasis of transcription factors functioning as repressors and activators.

Jasmonate: A Versatile Messenger in Plants

This chapter presents a summary of recent advances in the understanding of JA synthesis and signaling along with its role in regulating physiology of plant in presence or absence of biotic stress.

Lipoxygenase Inhibition Activity of Coumarin Derivatives—QSAR and Molecular Docking Study

QSAR and molecular docking studies elucidated the structural features important for the enhanced inhibitory activity of the most active compounds, such as the presence of the benzoyl ring at the 3-position of coumarin’s core.

Lipoxygenase Inhibition by Plant Extracts

This review summarized recent research on plant families and species that can inhibit lipoxygenase activity that play an important role in stimulation of inflammatory reactions.



Divinyl ether synthesis in garlic bulbs.

Data indicate that the product pattern of this DES from garlic depends on the substrate availability and that the enzyme is the first member in the group of 9/13-DES, which is a member of the CYP74C subfamily of cytochrome P-450 enzymes.

Biosynthesis of new divinyl ether oxylipins in Ranunculus plants

Analysis by reversed-phase high-performance liquid radiochromatography demonstrated the formation of a new divinyl ether FA, i.e., 12-[1′(E), 3′(Z)-hexadienyloxy]-9(Z), 11-Z)-dodecadienoic acid [11(Z-etherolenic acid] as well as a smaller proportion of ω5(Z)etheroleic acid previously identified in terrestrial Ranunculus plants.

A pathway for biosynthesis of divinyl ether fatty acids in green leaves

Incubations of isomeric hydroperoxides derived from α-linolenic and linoleic acids with the enzyme preparation from R. acris showed that 13(S)-hydroperoxy-9(Z), 11(E)-octadecadienoic acid was transformed into the divinyl ether 12-[1′(Z)-hexenyloxy]-9-Z, 11-E-dodecadienOic acid.

Biosynthesis of C9-aldehydes in the moss Physcomitrella patens.

On the mechanism of biosynthesis of divinyl ether oxylipins by enzyme from garlic bulbs.

Experiments with linoleic acid (13R,S)-hydroperoxide demonstrated that the S enantiomer was a much better substrate for the divinyl ether synthase compared to the R enantiomers.

Isolation and structures of two divinyl ether fatty acids from Clematis vitalba

Separate incubation of the 9- and 13-hydroperoxides of linolenic acid demonstrated that the first hydroperoxide served as the precursor of 8(Z)-colnelenic acid and indicated the presence in C. vitalba of a new divinyl ether synthase acting on 9-lipoxygenase-generated hydroperoxide.
