(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.

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.

(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 supported 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.

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".
