TranscriptomicsThe maize death acids, 10-oxo-11-phytoenoic acid and derivatives, are rapidly induced phytoalexins with multiple biological activities
Plant cellular damage promotes the interaction of lipoxygenases (LOX) with free fatty acids to yield 9- and 13-hydroperoxides which are further metabolized into diverse oxylipins. The enzymatic action of 13-LOX on linolenic acid enables production of 12-oxo-phytodienoic acid (12-OPDA) and its downst...

TranscriptomicsTranscription profiling of Arabidopsis male-sterile opr3 mutant stamens treated with jasmonate or its precursor, 12-oxophytodienoic acid
In Arabidopsis, jasmonate is required for stamen and pollen maturation. Mutants deficient in jasmonate synthesis, such as opr3, are male-sterile but become fertile when jasmonate is applied to developing flower buds. We have used ATH1 oligonucleotide arrays to follow gene expression in opr3 stamens...

TranscriptomicsMaize death acids, 9-lipoxygenase derived cyclopente(a)nones, display activity as cytotoxic phytoalexins and transcriptional mediators
Plant damage promotes the interaction of lipoxygenases (LOX) with fatty acids yielding 9-hydroperoxides, 13-hydroperoxides and complex arrays of oxylipins. The action of 13-LOX on linolenic acid enables production of 12-oxo-phytodienoic acid (12-OPDA) and its downstream products, termed jasmonates. ...

TranscriptomicsMicroarray analysis of rice ZH11 and OPR3 overexpression plants
The plant hormone jasmonic acid (JA) plays a central role in plant defense responses.12-oxo-phytodienoic acid (OPDA) reductase 3 (OPR3) is a key enzyme in the JA synthesis pathway.To discover what facilitates defense functions in the JA pathway, we conducted a microarray analysis of OPR3 overexpress...

TranscriptomicsTranscription profiling of Arabidopsis defective in the expression of TGA2, TGA5, and TGA6
12-oxo-phytodienoic acid (OPDA) and phytoprostane A1 (PPA1) are cyclopentenone oxylipins that are formed via the enzymatic; jasmonate pathway and a nonenzymatic, free radical–catalyzed pathway, respectively. Both types of cyclopentenone oxylipins; induce the expression of genes related to detoxifi...

TranscriptomicsConjugation of dn-OPDA with amino acids inhibits its hormonal bioactivity in Marchantia polymorpha
Jasmonates are important phytohormones activating plant tolerance to biotic and abiotic stress, as well as different development processes. These responses are mediated by a conserved signalling pathway activated by different hormones in different plants: dinor-12-oxo-phytodienoic acid (dn-OPDA) iso...

TranscriptomicsResponse of Arabidopsis cell culture to phytoprostane A1
12-Oxo-phytodienoic acid (OPDA) and several phytoprostanes are structurally related cyclopentenone oxylipins that can be formed via the enzymatic jasmonate pathway and a non-enzymatic, free radical-catalyzed pathway, respectively. To elucidate the biological activities of phytoprostanes in compariso...
