Kramell, R., Miersch, O., Atzorn, R., Parthier, B. & Wasternack, C. Octadecanoid-derived alteration of gene expression and the 'oxylipin signature' in stressed barley leaves - implications for different signalling pathways Plant Physiol. 123, 177-186, (2000)

Stress-induced gene expression in barley (Hordeum vulgare cv. Salome) leaves has been correlated with temporally changing levels of octadecanoids and jasmonates, quantified by means of gas chromatography/mass spectrometry-single ion monitoring. Application of sorbitol-induced stress led to a low and transient rise of jasmonic acid (JA), its precursor 12-oxophytodienoic acid (OPDA) and the methyl esters JAME and OPDAME, respectively, followed by a large increase in their levels. JA and JAME peaked between 12 and 16 h, about 4 hours before OPDA and OPDAME. However, OPDA accumulated up to a 2.5-fold higher level than the other compounds. Dihomo-jasmonic acid and 9,13-didehydro-12- oxophytoenoic acid were identified as minor components. Kinetic analyses revealed that a transient threshold of jasmonates or octadecanoids is necessary and sufficient to initiate JA responsive gene expression. Although OPDA and OPDAME applied exogenously were metabolized to JA in considerable amounts, both of them can induce gene expression per se as evidenced by those genes which do not respond to endogenously formed JA. Also, coronatine induces JA-responsive genes independently from endogenous JA. As evidenced by application of deuterated JA, endogenous synthesis of JA is not induced by JA treatment. The data are discussed in terms of distinct signalling pathways.
