“…To date, its presence has also been reported in Solanum demissum (38) and in the fungus B. theobromae (30). The glucoside of 12-OHJA has also been detected in Helianthus tuberosus (39) and Astragalus complanatus (40). The presence of 12-OHJA in A. thaliana indicates that its distribution can no longer be considered to be restricted to tuber-producing plants and it raises interesting questions about its function in plants that do not produce tubers.…”

12-Hydroxyjasmonate, also known as tuberonic acid, was first isolated from Solanum tuberosum and was shown to have tuber-inducing properties. It is derived from the ubiquitously occurring jasmonic acid, an important signaling molecule mediating diverse developmental processes and plant defense responses. We report here that the gene AtST2a from Arabidopsis thaliana encodes a hydroxyjasmonate sulfotransferase. The recombinant AtST2a protein was found to exhibit strict specificity for 11-and 12-hydroxyjasmonate with K m values of 50 and 10 M, respectively. Furthermore, 12-hydroxyjasmonate and its sulfonated derivative are shown to be naturally occurring in A. thaliana. The exogenous application of methyljasmonate to A. thaliana plants led to increased levels of both metabolites, whereas treatment with 12-hydroxyjasmonate led to increased level of 12-hydroxyjasmonate sulfate without affecting the endogenous level of jasmonic acid. AtST2a expression was found to be induced following treatment with methyljasmonate and 12-hydroxyjasmonate. In contrast, the expression of the methyljasmonate-responsive gene Thi2.1, a marker gene in plant defense responses, is not induced upon treatment with 12-hydroxyjasmonate indicating the existence of independent signaling pathways responding to jasmonic acid and 12-hydroxyjasmonic acid. Taken together, the results suggest that the hydroxylation and sulfonation reactions might be components of a pathway that inactivates excess jasmonic acid in plants. Alternatively, the function of AtST2a might be to control the biological activity of 12-hydroxyjasmonic acid.

“…Four tuber-forming substances were isolated from the leaves: jasmonic acid, methyl β-Dglucopyranosyl tuberonate and two new polyacetylene compounds, methyl 10-O -glucopyranosyl helianthenate A and methyl 8-O -glucopyranosyl helianthenate B (Matsuura et al 1993b ); four polyacetylenic glucosides were characterised as methyl 10-β-D -glucopyranosyloxy -3-hydroxy-11-dodecene-6,8-dynoate, the aglycone part named helianthenic acid C; methyl 9-β-Dglucopyranosyloxy-10-undecen-5,7-diynoate, the aglycone part named helianthenic acid D; (4 E ) methyl 10-β-D -glucopyranosyloxy -3-hydroxy-4,11-dodecadiene-6,8-diynoate, the aglycone part named helianthenic acid E and (8 Z ) 10-β-Dglucopyranosyloxy -8-decene-4,6-diynoate the aglycone part named helianthenic F (Matsuura et al 1993a ); six sesquiterpenoids, α-acetoxypinnatifi din; α-hydroxypinnatifi din; budlein A; 17, 18-dehydroviguiepinin; 4,15-isoatriplicolide angelate and 4,15-isoatriplicolide methacrylate (Baba et al 2005 ) were isolated from the leaves. Two Jerusalem artichoke chemotypes were found: one was characterised by dominance of 1,10-epoxidised heliango lides and the other by 1-keto-2,3-unsaturated-furanoheliangolides; a total of 19 such sesquiterpene lactones were found in the leaf capitate glandular trichomes (Spring 1991 ); 7 chlorogenic acids comprise three caffeoylquinic acids, one feruloylquinic acid and three dicaffeoylquinic acids (Yuan et al 2008c (Choi et al 2012 ).…”

“…The second resistance system is classified as wound induced systemic resistance, and jasmonic acid (JA) is associated with this resistance system. JA and related cyclopentanones are also known as important signaling molecules to control other biological processes such as senescence, potato-tuber formation, and anther development (Koda et al 1998;McConn and Browse 1996;Yoshihara et al 1989;Matsuura et al 1993). Another kind of JA-dependent response is known and named as induced systemic resistance, which is the systematic resistance induced by root colonizing bacteria, such as nonpathogenic rhizobacteria, that enhances the plant defense system.…”

Jasmonic acid (JA) and salicylic acid (SA) are plant hormones involved in plant growth and development. Recent studies demonstrated that presence of a complex interplay between JA and SA signaling pathways to response to pathogenesis attack and biotic stresses. To our best knowledge, no method has existed for simultaneous analyses of JA, SA, and their related compounds. Especially, the glucosides are thought to be the storages or the inactivated compounds, but their contribution should be considered for elucidating the amount of the aglycons. It is also valuable for measuring the endogenous amount of phenylalanine, cinnamic acid, and benzoic acid that are the biosynthetic intermediates of SA due to the existence of isochorismate pathway to synthesize SA. We established this method using deuterium labeled compounds as internal standards. This is the first report of simultaneous analysis of endogenous JA, SA, and their related compounds. Measuring the endogenous JA, SA, and their related compounds that had been accumulated in tobacco plants proved the practicality of the newly developed method. It was demonstrated that accumulation of JA, SA and their related compounds were induced in both case of TMV infection and abiotic stresses.
