(2009) Velocity estimates for signal propagation leading to systemic jasmonic acid accumulation in wounded Arabidopsis. J. Biol. Chem. 284, 34506-34513. At the time of this publication groups studying long distance (systemic) defense signaling in Arabidopsis did not take interleaf vascular architecture (parastichies) into account. Doing so allowed us to improve on velocity estimates for JA accumulation in distal leaves (Glauser et al., 2008) and provide the first constrained estimate of signal velocity for a systemic wound response in plants.

J. Biol. Chem. 283, 16400-16407 *corresponding author. This paper demonstrated that JA synthesis in leaves distal to the wounded leaf is rapid, in the region of 2-5 min after wounding and we proposed that a signal travels at at least 3 cm per min to stimulate JA synthesis distal to wounds. We also identified a new oxylipin: a highly oxidized form of jasmonoyl-isoleucine.

Confirms that the oxylipin signature concept is correct and shows that OPDA and dinor-OPDA are the key compounds necessary for resistance to an insect and a pathogen. Suggests that cyclopentenone jasmonates might have some electrophilic properties in vivo.

(2000) Differential gene expression in response to mechanical wounding and insect feeding in Arabidopsis. Plant Cell 12, 707-719. Details This microarray analysis of responses to herbivory in Arabidopsis suggested an important role for jasmonates in gene expression following insect damage. Interestingly, genes that are strongly upregulated in mechanically crushed tissues and also induced during dehydration were less activated by insects. The implication is that insect feeding strategies might minimise the cut leaf surface exposed to the air. This, of course, might help explain why insects often cut circles and semi-circles in leaves.
Weber, H., Chételat, A., Caldelari, D. and Farmer, E.E. (1999) Divinyl ether fatty acid synthesis in late blight diseased potato leaves. Plant Cell 11, 485-493. Many studies on antibiotics (phytoalexins) made in potato in response to the devastating pathogen Phytophora infestans have concentrated on tubers. We looked at the primary infection sites, leaves, and were surprised to find very high levels of fatty acid divinyl ethers which we describe as "phytoalexin-like compounds". Introduces the term "late-phase oxylipins" for oxylipins made or accumulating at late stages in pathogenesis.
