Determination of the level of resistance and the induction of defense responses in plants with altered JA components, through mutation or ectopic expression, will unveil novel mechanisms of JA signaling. Jasmonic acid is an oxo monocarboxylic acid that is (3-oxocyclopentyl)acetic acid substituted by a (2Z)-pent-2-en-1-yl group at position 2 of the cyclopentane ring.

Despite the efficacy of aphid resistance in soybean, virulent aphids have overcome this resistance through mostly unknown mechanisms. The shoot fresh mass, root length and root numbers of two potato (Solanum tuberosum L.) cultivars Favorita and Helanwuhua were increased significantly by the application of 0.2 - 2 mg dm-3 jasmonic acid (JA) in the Murashige and Skoog medium. Planta. It is a conjugate acid of a jasmonate (1-). Plant Cell 19(8):2470–2483. Jasmonic acid and methyl jasmonate are now known to be distributed widely among higher plants [6,7], and are assumed to be acting as plant-growth substances.

During the gravitropic response in rice coleoptiles, JA accumulates to a higher level in the upper flank and to a lower level in the lower flank (Gutjahr et al., 2005).

Furthermore, JA signaling is essential in interactions of plants with beneficial microbes that induce systemic resistance to pathogens and insects. Jasmonates are usually quantified by liquid chromatography-mass spectrometry (LC-MS) analysis of precursors and products in the biosynthetic pathway or inferred from the extraction and expression of genes known to respond to elevated levels of JA. Cite as. In addition, we describe pharmacological assays to study the modulation of JA-regulated responses by exogenous application of combinations of hormones, because a simultaneous rise in hormone levels occurs during interaction of plants with other organisms. JA and MeJA are plant lipid derivatives synthesized from [alpha]-linolenic acid by a lipoxygenase-mediated oxygenation leading to 13-hydroperoxylinolenic acid, which is subsequently transformed by the action of allene oxide synthase (AOS) and additional modification steps.

Jasmonic acid and methyl jasmonate have been shown previously to be powerful inducers of proteinase inhibitors in tomato, tobacco, and alfalfa leaves. Phytochemistry 70(13–14):1571–1580. Jasmonic acid is a plant growth inhibitor possessing a relative activity in the wheat seedling bioassay of 1–2.5%, compared to ABA. Feeding by chewing insects induces chemical defenses in plants that are regulated by the jasmonic acid (JA) pathway. Here, we describe a detailed and reproducible protocol for testing feeding behavior of the generalist herbivore Spodoptera littoralis on the model plant Arabidopsis thaliana and hence infer the contribution of JA-mediated plant defense responses to a chewing insect. Jasmonates induce both defense responses and communication in monocotyledonous and dicotyledonous plants. Proceedings of the National Academy of Sciences, USA.

Jasmonic acid (JA) signaling is required for plant resistance to harmful organisms, such as necrotrophic pathogens and herbivorous insects. It is biosynthesized from linolenic acid by the octadecanoid pathway. To lead the discovery of jasmonic acid (JA)‐regulated specialized metabolites with potential in inhibiting human breast cancer cell growth, we ran linear regression models on the normalized (zero mean and unit variance) log 2 ‐transformed abundances of each metabolite (total of 1757) with subsequent tests of a priori defined treatment contrasts (Hothorn et al., 2008). Methods Mol Biol. Annu Rev Entomol 61:373–394. 2001, 214: 171-179. Plant Cell … It has a role as a plant metabolite and a member of jasmonates.
