Wasternack, C.; Hause, B. OPDA-Ile – a new JA-Ile-independent signal? Plant Signal Behav 11, e125364600, (2016) DOI: 10.1080/15592324.2016.1253646

AbstractExpression takes place for most of the jasmonic acid (JA)-induced genes in a COI1- dependent manner via perception of its conjugate JA-Ile in the SCFCOI1-JAZ co-receptor complex. There are, however, numerous genes and processes, which are preferentially induced COI1-independently by the precursor of JA, 12-oxo-phytodienoic acid (OPDA). After recent identification of the Ile-conjugate of OPDA, OPDA-Ile, biological activity of this compound could be unequivocally proven in terms of gene expression. Any interference of OPDA, JA, or JA-Ile in OPDA-Ile-induced gene expression could be excluded by using different genetic background. The data suggest individual signaling properties of OPDA-Ile. Future studies for analysis of an SCFCOI1-JAZ co-receptor-independent route of signaling are proposed.
