The results of methanol‐trapping experiments demonstrate that both 12‐oxo‐PEA and α‐ketol are formed through the unstable allene oxide intermediate, (9Z)‐12,13‐epoxyoctadeca‐9,11‐dienoic acid, which is the primary product of allenes oxide synthase.
Screening of divinyl ether synthase activity in nonphotosynthetic tissue of asparagales
The finding of a novel divinyl ether synthase in nonphotosynthetic tissues of some plants of the order Asparagales is reported, indicating a new role for lipoxygenase metabolic signalling in plants with unstudied or poorly studied genomes.

Gene Expression Analysis of Potato (Solanum tuberosum L.) Lipoxygenase Cascade and Oxylipin Signature under Abiotic Stress
The metabolism of polyunsaturated fatty acids through the lipoxygenase-catalyzed step and subsequent reactions is referred to as the lipoxygenase (LOX) pathway. The components of this system, such as…

Abstract —The activity of divinyl ether synthase (EC: 126.96.36.199), an enzyme involved in the lipoxygenase cascade of unsaturated fatty acids in plants, has been found in the roots and stalks of…
Differential modulation of the lipoxygenase cascade during typical and latent Pectobacterium atrosepticum infections.
The obtained data demonstrate that when compared to the typical infection, latent asymptomatic P. atrosepticum infection is associated with decreased levels of 9-lipoxygenase branch products and jasmonic acid and increased level of cis-12-oxo-10,15-phytodienoic acid, contributing to the hypothesis of the oxylipin signature.

Young roots of wheat, barley, and sorghum, as well as methyl jasmonate pretreated rice seedlings, undergo an unprecedented allene oxide synthase pathway targeted to previously unknown oxylipins 1–3, indicating that conversion of the allenes oxide into the cyclopropanone is controlled by soluble cyclase.
