Rudus, I.; Kepczynska, E.; Kepczynski, J.; Wasternack, C.; Miersch, O.; Changes in jasmonates and 12-oxophytodienoic acid contents of Medicago sativa L. during somatic embryogenesis Acta Physiol. Plant. 27, 497-504, (2005) DOI: 10.1007/s11738-005-0055-x

Jasmonic acid (JA), its methyl ester (MeJA) and the biosynthetic precursor 12-oxophytodienoic acid (OPDA) were detected quantitatively during somatic embryogenesis of Medicago sativa L. Using GC-MS analysis, these compounds were found in initial explants, in calli and in somatic embryos in the nanogram range per gram of fresh weight. In distinct stages of somatic embryogenesis, JA and 12-OPDA accumulated preferentially in cotyledonary embryos. Initial explants exhibited about five-fold higher JA content than OPDA content, whereas in other stages OPDA accumulated predominantly. These data suggest that also in embryogenic tissues OPDA and JA may have individual signalling properties.

In plants, the oxylipin pathway gives rise to several oxygenated fatty acid derivatives such as hydroxy- and keto fatty acids as well as volatile aldehydes and cyclic compounds, which are, in part, physiologically active [1]. Among these, jasmonic acid is discussed as signalling molecule during several stress responses, wounding, senescense and plant pathogen interactions [2].
