The Hydroperoxide Lyase Branch of the Oxylipin Pathway and Green Leaf Volatiles in Plant/Insect Interaction
Author(s): Marco Taurino, Stefania De Domenico, Stefania Bonsegna and Angelo Santino*
The lipoxygenase (LOX) catalysed peroxidation of polyunsaturated fatty acids (PUFA) is a key starting point in
defence mechanisms common to plant, animal and at least some microorganisms. In human, the peroxidation of
arachidonic acid finally leads to the biosynthesis of important defence effectors such as leukotrienes and lipoxins.
In plant, the most common substrates of lipoxygenases are represented by linoleic (C18:2) and linolenic (C18:3)
acids. Differently from auto-oxidation reactions which produce a huge number of hydroperoxide derivatives, the
oxidation reaction catalysed by LOXs is positional and stereo-specific. Indeed, only 9- or 13-hydroperoxides (with
a prevalence of the S steroisomers) are produced from these substrates. PUFA hydroperoxides are per se signal
molecules or c.. View More»
