Journal ArticleDOI
Volatile Signaling in Plant-Plant Interactions: "Talking Trees" in the Genomics Era
TL;DR: This article showed that plants may "eavesdrop" on volatile organic compounds (VOCs) released by herbivore-attacked neighbors to activate defenses before being attacked themselves.
Journal ArticleDOI
A knock-out mutation in allene oxide synthase results in male sterility and defective wound signal transduction in Arabidopsis due to a block in jasmonic acid biosynthesis.
Joon Hyun Park,Rayko Halitschke,Ho Bang Kim,Ian T. Baldwin,Kenneth A. Feldmann,Kenneth A. Feldmann,René Feyereisen +6 more
TL;DR: The results show that AOS is critical for the biosynthesis of all biologically active jasmonates, but that the AOS hydroperoxide substrate levels, controlled by upstream enzymes (lipoxygenase and phospholipase), determine JA levels in unwounded plants.
Journal ArticleDOI
Molecular interactions between the specialist herbivore Manduca sexta (Lepidoptera, Sphingidae) and its natural host Nicotiana attenuata. III. Fatty acid-amino acid conjugates in herbivore oral secretions are necessary and sufficient for herbivore-specific plant responses
TL;DR: It is concluded that the biological activity of R is not related to the supply of FAs to the octadecanoid cascade for endogenous jasmonate biosynthesis, but that FACs elicit the herbivore-specific responses by another mechanism and that the insect-produced modification of plant-derived FAs is necessary for the plant's recognition of this specialized Herbivore.
Journal ArticleDOI
Silencing the Jasmonate Cascade: Induced Plant Defenses and Insect Populations
TL;DR: Results show that lipoxygenase-dependent signaling determines host selection for opportunistic herbivores and that induced defenses influence herbivore community composition.
Journal ArticleDOI
Nicotine's defensive function in nature.
TL;DR: It is demonstrated that silencing pmt inhibits nicotine production, while the excess NA dimerizes to form anatabine, providing strong evidence that nicotine functions as an efficient defense in nature and highlights the value of transgenic techniques for ecological research.
