Journal ArticleDOI
Differential Gene Expression in Response to Mechanical Wounding and Insect Feeding in Arabidopsis
TL;DR: A feeding strategy of P. rapae is revealed that may minimize the activation of a subset of water stress–inducible, defense-related genes that contribute to tissue defense and repair.
Journal ArticleDOI
Auxin response factors ARF6 and ARF8 promote jasmonic acid production and flower maturation

TL;DR: Arf6 and arf8 single mutants and sesquimutants had delayed stamen development and decreased fecundity, indicating that ARF6 and ARF8 gene dosage affects timing of flower maturation quantitatively.
Journal ArticleDOI
Fatty acid-derived signals in plants
TL;DR: The jasmonate biosynthesis mutant opr3 allowed the dissection of cyclopentanone and Cyclopentenone signalling, thus defining specific roles for these molecules.
Journal ArticleDOI
Dinor-oxo-phytodienoic acid: a new hexadecanoid signal in the jasmonate family.
TL;DR: Treatment of Arabidopsis with micromolar levels of dinor-oxo-phytodienoic acid increased the ability of leaf extracts to transform linoleic acid into the alpha-ketol 13-hydroxy-12-Oxo-9(Z) octadecenoic acid indicating that the compound can regulate part of its own biosynthetic pathway.
Journal ArticleDOI
Selective and powerful stress gene expression in Arabidopsis in response to malondialdehyde.
TL;DR: Genetic confirmation of the hypothesis that MDA originates from fatty acids containing more than two methylene-linked double bonds is provided, showing that tri-unsaturated fatty acids are the in vivo source of up to 75% of MDA.
