Cis-(+)-12-oxo-phytodienoic acid (OPDA) is likely to play signaling roles in plant defense that do not depend on its further conversion to the phytohormone jasmonic acid. To elucidate the role of OPDA in Solanum lycopersicum (tomato) plant defense, we have silenced the 12-oxophytodienoate reductase 3 (OPR3) gene. Two independent transgenic tomato lines (SiOPR3-1 and SiOPR3-2) showed significantly reduced OPR3 expression upon infection with the necrotrophic pathogen Botrytis cinerea. Moreover…

Oxylipins Other Than Jasmonic Acid Are Xylem-Resident Signals Regulating Systemic Resistance Induced by Trichoderma virens in Maize

A model that differential regulation of 12-OPDA and JA in response to T. virens colonization results in ISR induction is proposed, which shows that a maize 13-lipoxygenase mutant, lox10, colonized by the wild-type T. Virens (TvWT) lacked ISR response against Colletotrichum graminicola but instead displayed induced systemic susceptibility.

Hexanoic Acid Treatment Prevents Systemic MNSV Movement in Cucumis melo Plants by Priming Callose Deposition Correlating SA and OPDA Accumulation

The basal response of melon to Melon necrotic spot virus (MNSV) is studied and the efficacy of hexanoic acid (Hx) priming is demonstrated, which prevents the virus from systemically spreading.

Role of Jasmonic Acid Pathway in Tomato Plant-Pseudomonas syringae Interaction

It is suggested that a complete jasmonic acid pathway is necessary for the susceptibility of tomato plants to Pseudomonas syringae and treatments with JA restore the susceptibility as well as activate the expression of bacterial pathogenicity genes.

OPDAT1, a plastid envelope protein involved in 12-oxo-phytodienoic acid export for jasmonic acid biosynthesis in Populus.

Plastid inner envelope-localized protein OPDAT1 was identified and shown to potentially be involved in OPDA export from plastids, in Populus trichocarpa, and this has potential implications for JA biosynthesis in poplar under environmental stresses.

The cell-wall-localised BETA-XYLOSIDASE 4 contributes to immunity of Arabidopsis against Botrytis cinerea

It is suggested that remodelling or degradation of one or more cell wall polysaccharides is important for plant immunity against B. cinerea and plays a role in pathogen-induced JA-Ile and camalexin accumulation.

Genome-Wide Analysis of OPR Family Genes in Cotton Identified a Role for GhOPR9 in Verticillium dahliae Resistance

The results provided the evolution and potential functions of the OPR genes in cotton and suggested that GhOPR9 might play an important role in cotton resistance to V. dahliae.



Plant defense in the absence of jasmonic acid: The role of cyclopentenones

It is concluded that the jasmonate family cyclopentenone OPDA regulates gene expression in concert with JA to fine-tune the expression of defense genes.

The Arabidopsis male-sterile mutant, opr3, lacks the 12-oxophytodienoic acid reductase required for jasmonate synthesis.

Results indicate that JA and not OPDA is the signaling molecule that induces and coordinates the elongation of the anther filament, the opening of the stomium at anthesis, and the production of viable pollen, and demonstrate that OPR3 is the only isoform of OPR capable of reducing the correct stereoisomer of OPDA to produce JA required for male gametophyte development.

An octadecanoid pathway mutant (JL5) of tomato is compromised in signaling for defense against insect attack.

Results show that octadecanoid metabolism plays an essential role in the transduction of upstream would signals to the activation of antiherbivore plant defenses.

Resistance to Botrytis cinerea in sitiens, an Abscisic Acid-Deficient Tomato Mutant, Involves Timely Production of Hydrogen Peroxide and Cell Wall Modifications in the Epidermis1[C][W][OA]

Although, in general, plant defense-related reactive oxygen species formation facilitates necrotrophic colonization, data indicate that timely hyperinduction of H2O2-dependent defenses in the epidermal cell wall can effectively block early development of B. cinerea.

The Tomato Homolog of CORONATINE-INSENSITIVE1 Is Required for the Maternal Control of Seed Maturation, Jasmonate-Signaled Defense Responses, and Glandular Trichome Development Online version contains Web-only data. Article, publication date, and citation information can be found at

It is demonstrated that the tomato homolog of CORONATINE-INSENSITIVE1 (COI1), an F-box protein that is required for JA-signaled processes in Arabidopsis, regulates distinct developmental processes in different plants and suggests a role for JA in the promotion of glandular trichome–based defenses.

Oxylipin Signaling: A Distinct Role for the Jasmonic Acid Precursor cis-(+)-12-Oxo-Phytodienoic Acid (cis-OPDA)

A novel role for cis-OPDA in seed germination regulation has recently been uncovered based on evidence from double mutants and feeding experiments showing that cis-opDA interacts with abscisic acid (ABA), inhibits seed gernation, and increases ABA INSENSITIVE5 (ABI5) protein abundance.

Intronic T-DNA Insertion Renders Arabidopsis opr3 a Conditional Jasmonic Acid-Producing Mutant1[C][W][OA]

Data are reinforced to reinforce the primary role JAs play in plant defense against insects and necrotrophic fungi, argue for a reassessment of signaling activities ascribed to OPDA, and provide evidence that mutants with intron insertions can retain gene function.

12-Oxo-Phytodienoic Acid Triggers Expression of a Distinct Set of Genes and Plays a Role in Wound-Induced Gene Expression in Arabidopsis1[w]

Microarray analysis of Arabidopsis genes revealed that an OPDA signaling pathway functions independently of JA/MeJA signaling and is required for the wounding response inArabidopsis.

Hexanoic acid is a resistance inducer that protects tomato plants against Pseudomonas syringae by priming the jasmonic acid and salicylic acid pathways.

It is observed that Hx seems to inhibit stomatal opening in Planta in the presence of COR, which suggests that, on infection in tomato, this treatment suppresses effector action to prevent bacterial entry into the mesophyll.

Pathogen-induced systemic activation of a plant defensin gene in Arabidopsis follows a salicylic acid-independent pathway.

The results indicate that systemic pathogen-induced expression of the plant defensin gene in Arabidopsis is independent of salicylic acid but requires components of the ethylene and jasmonic acid response.
