“…JA and its methyl ester have been reported to induce a number of wound-or pathogen-responsive plant defense genes (Andresen et al, 1992;Creelman et al, 1992;Dittrich et al, 1992;Gundlach et al, 1992). Furthermore, octadecanoid precursors of JA strongly induced proteinase inhibitors in tomato .…”

“…This hypothesis is based on the observation that exogenously applied jasmonate induces wound-responsive (Creelman et al, 1992;Hildmann et al, 1992) and pathogen-responsive (Dittrich et al, 1992;Gundlach et al, 1992) genes in several plants and secondary metabolites in suspension-cultured cells of 36 monocot and dicot species (Gundlach et al, 1992). Moreover, wounding (Creelman et al, 1992) and elicitor treatment (Gundlach et al, 1992) have been reported to cause a rapid increase of the endogenous JA pool.…”

“…Other groups extended these results using additional plant cell cultures, e.g. parsley (Petroselinum crispum; Dittrich et al, 1992), Taxus cuspidata (Mirjalili and Linden, 1996), rice (Norjiri et al, 1996) or Lithospermum erythrorhizon (Mühlenweg et al, 1998). Remarkably, the treatment with JA did not result for all species in the production of phytoalexins, inducible low molecular weight compounds with antimicrobial properties correlating with plant defense.…”

Oxylipins of the jasmonate pathway and synthetic functional analogs have been analyzed for their elicitor-like activities in an assay based on the induced accumulation of glyceollins, the phytoalexins of soybean (Glycine max L.), in cell suspension cultures of this plant. Jasmonic acid (JA) and its methyl ester showed weak phytoalexin-inducing activity when compared to an early jasmonate biosynthetic precursor, 12-oxo-phytodienoic acid (OPDA), as well as to the bacterial phytotoxin coronatine and certain 6-substituted indanoyl-L-isoleucine methyl esters, which all were highly active. Interestingly, different octadecanoids and indanoyl conjugates induced the accumulation of transcripts of various defense-related genes to different degrees, indicating distinct induction competencies. Therefore, these signaling compounds and mimics were further analyzed for their effects on signal transduction elements, such as the transient enhancement of the cytosolic Ca 2 + concentration and MAP kinase activation, which are known to be initiated by a soybean pathogen-derived ␤-glucan elicitor. In contrast to the ␤-glucan elicitor, none of the other compounds tested triggered these early signaling elements. Moreover, endogenous levels of OPDA and JA in soybean cells were shown to be unaffected after treatment with ␤-glucans. Thus, OPDA and JA, which are functionally mimicked by coronatine and a variety of 6-substituted derivatives of indanoyl-L-isoleucine methyl ester, represent highly efficient signaling compounds of a lipid-based pathway not deployed in the ␤-glucan elicitor-initiated signal transduction.

“…In Arabidopsis, OPDA can activate wound-induced gene expression in the absence of JA (Taki et al, 2005). In parsley (Petroselinum crispum), soybean (Glycine max), and bean, either OPDA or JA promotes the synthesis of flavonoids and the expression of their biosynthetic genes (Franceschi and Grimes, 1991;Dittrich et al, 1992;García-Ponce and Rocha-Sosa, 2000). In addition to oxylipins, ethylene has also been implicated in the activation of systemic plant defenses in response to pathogens (Penninckx et al, 1998) and wounding (O'Donnell et al, 1996).…”

Hormonal and Stress Induction of the Gene Encoding Common Bean Acetyl-Coenzyme A Carboxylase

Regulation of the cytosolic acetyl-coenzyme A carboxylase (ACCase) gene promoter from common bean (Phaseolus vulgaris) was studied in transgenic Arabidopsis (Arabidopsis thaliana) plants using a β-glucuronidase (GUS) reporter gene fusion (PvACCase∷GUS). Under normal growth conditions, GUS was expressed in hydathodes, stipules, trichome bases, flowers, pollen, and embryos. In roots, expression was observed in the tip, elongation zone, hypocotyl-root transition zone, and lateral root primordia. The PvACCase promoter was induced by wounding, Pseudomonas syringae infection, hydrogen peroxide, jasmonic acid (JA), ethylene, or auxin treatment. Analysis of PvACCase∷GUS expression in JA and ethylene mutants (coronatine insensitive1-1 [coi1-1], ethylene resistant1-1 [etr1-1], coi1-1/etr1-1) suggests that neither JA nor ethylene perception participates in the activation of this gene in response to wounding, although each of these independent signaling pathways is sufficient for pathogen or hydrogen peroxide-induced PvACCase gene expression. We propose a model involving different pathways of PvACCase gene activation in response to stress.
