“…It is important to note that, even if they are not presented in this figure, oxylipin pathways exist in other members of the Plantae reign (mosses, algae, etc.) [1,8,9]. FA, fatty acid; LOX, lipoxygenase; α-DOX, α-dioxygenase; AOC, allene oxide cyclase; AOS, allene oxide synthase; DES, divinyl ether synthase; EAS, epoxy alcohol synthase; HPL, hydroperoxide lyase.…”

Almost 30 years ago, the term 'oxylipin' (see Glossary) appeared in the literature and since then, publications on the topic have increased steadily. Oxylipins are found in almost all organisms and are present in free forms, esterified to phospholipids or galactolipids, or combined with other compounds (e.g., methyl groups, isoleucine) [1-10]. The precursors of oxylipin synthesis vary among organisms, as do the enzymes that will oxidise them. Because aerobic biological systems are continuously subject to autooxidation, oxylipins (e.g., phytoprostanes) are also produced through nonenzymatic routes in the presence of singlet oxygen or reactive oxygen species (ROS) [3,11-15]. Both pathways have been extensively reviewed. Figure 1 summarises the enzymatic production pathways of oxylipins (free forms) in mammals, fungi, and flowering plants (for detailed information see [8,13-21]).

“…Numerous JA derivatives occur also in the fungus Fusarium oxysporum [ 20 ] with the allene oxide 12,13( S )-epoxy-octadecatrienoic acid and OPDA as key intermediates [ 21 ], which indicates similarity of JA formation between fungi and plants. The JA precursor OPDA, but not JA, have been detected in Marchantia polymorpha [ 22 ], in the moss Physcomitrella patens [ 23 ] and in one of the oldest vascular plants, the spikemoss Selaginella martensii [ 24 ], whereas in S. moellendorffii OPDA and JA were detected [ 25 ]. Even though no JA occurs in M. polymorpha , essential components of JA signaling have been found suggesting occurrence of another ligand than JA-Ile [ 11 ].…”

Jasmonic acid (JA) and its related derivatives are ubiquitously occurring compounds of land plants acting in numerous stress responses and development. Recent studies on evolution of JA and other oxylipins indicated conserved biosynthesis. JA formation is initiated by oxygenation of α-linolenic acid (α-LeA, 18:3) or 16:3 fatty acid of chloroplast membranes leading to 12-oxo-phytodienoic acid (OPDA) as intermediate compound, but in Marchantia polymorpha and Physcomitrella patens, OPDA and some of its derivatives are final products active in a conserved signaling pathway. JA formation and its metabolic conversion take place in chloroplasts, peroxisomes and cytosol, respectively. Metabolites of JA are formed in 12 different pathways leading to active, inactive and partially active compounds. The isoleucine conjugate of JA (JA-Ile) is the ligand of the receptor component COI1 in vascular plants, whereas in the bryophyte M. polymorpha COI1 perceives an OPDA derivative indicating its functionally conserved activity. JA-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.

“…Importantly, not all land plants produce jasmonic acid and its derivatives, but where jasmonates are absent their AOS-derived precursors such as OPDA are present. As an example, the aerial parts (microphylls) of the lycopod Selaginella martensii produce various isomers of OPDA and dinor-OPDA (Ogorodnikova et al , 2015) while no JA or JA-Ile are detected in this plant. The even more ancient liverwort Marchantia polymorpha produces biologically active AOS-derived dinor-OPDA isomers that regulate defense and growth (Monte et al , 2018) through a signaling pathway remarkably similar to the jasmonate pathway in angiosperms (Howe et al , 2018).…”
