Weichert, H.; Kohlmann, M.; Wasternack, C.; Feussner, I.; Metabolic profiling of oxylipins upon sorbitol treatment in barley leaves Biochem. Soc. Trans. 28, 861-862, (2001) DOI: 10.1042/bst0280861

In barley leaves 13-lipoxygenases (LOXs) are induced by salicylate and jasmonate. Here, we analyse by metabolic profiling the accumulation of oxylipins upon sorbitol treatment. Although 13-LOX-derived products are formed and specifically directed into the reductase branch of the LOX pathway, accumulation is much later than in the cases of salicylate and jasmonate treatment. In addition, under these conditions only the accumulation of jasmonates as additional products of the LOX pathway has been found.

Weichert, H.; Kolbe, A.; Wasternack, C.; Feussner, I.; Formation of 4-hydroxy-2-alkenals in barley leaves Biochem. Soc. Trans. 28, 850-851, (2000) DOI: 10.1042/bst0280850

In barley leaves 13-lipoxygenases are induced by jasmonates. This leads to induction of lipid peroxidation. Here we show by in vitro studies that these processes may further lead to autoxidative formation of (2E)-4-hydroxy-2-hexenal from (3Z)-hexenal.

O'Donnell, P. J.; Calvert, C.; Atzorn, R.; Wasternack, C.; Leyser, H. M. O.; Bowles, D. J.; Ethylene as a Signal Mediating the Wound Response of Tomato Plants Science 274, 1914-1917, (1996) DOI: 10.1126/science.274.5294.1914

Plants respond to physical injury, such as that caused by foraging insects, by synthesizing proteins that function in general defense and tissue repair. In tomato plants, one class of wound-responsive genes encodes proteinase inhibitor (pin) proteins shown to block insect feeding. Application of many different factors will induce or inhibit pin gene expression. Ethylene is required in the transduction pathway leading from injury, and ethylene and jasmonates act together to regulate pin gene expression during the wound response.
