“…An up-regulation of the allene oxide synthase (AOS) branch producing JA involves induction of lox and aos (Harms et al 1998), with JA or MeJA acting as a positive feedback regulator of its own biosynthesis, as observed in rice and tomato (Sivasankar et al 2000;Ha et al 2002;Xu et al 2003). Such a positive feedback loop was not observed in maize with C 6 -volatile treatment.…”

In response to insect feeding, corn plants (Zea mays cv. Delprim) release elevated levels of volatile organic compounds (VOCs), including the C(6)-volatile (Z)-3-hexenol. The level of mRNA accumulation for a series of defense genes was monitored in response to application of (Z)-3-hexenol (50 nmol) to undamaged plants. The induction of transcripts for hpl (hydroperoxide lyase), fps (farnesyl pyrophosphate synthase), pal (phenylalanine ammonia-lyase), lox (lipoxygenase), igl (indole-3-glycerol phosphate lyase) and mpi (maize proteinase inhibitor) were compared with metabolites generated from the respective pathways. While headspace VOC analysis showed an increase in (Z)-3-hexenyl acetate and methyl salicylate with lox and pal induction, respectively, MPI accumulation was not observed with an increase in mpi transcripts. Moreover, (Z)-3-hexenol treatment did not elevate sesquiterpene emissions or activate fps transcription. Chemical labeling and bioassay experiments established that exogenous (Z)-3-hexenol can be taken up and converted to a less active acetylated form. These data indicate that (Z)-3-hexenol can serve as a signaling molecule that triggers defense responses in maize and can rapidly be turned over in planta.

“…Increased endogenous jasmonate contents have been found in wounded plants, in plants suffering from drought and osmotic stress (Creelman et al 1992, Baldwin et al 1997, after treatment with fungal elicitors (Gundlach et al 1992, Farmer andRyan 1992) or upon pathogen attack (Xu et al 2003). In recent years jasmonates have been the focus of much attention because of their ability to provide protection to salinity stress (Tsonev et al 1998), UV irradiation (Mackerness et al 1999), or to increased freezing tolerance of bromegrass (Wilen et al 1994) which led to the suggestion that jasmonate could mediate the defense response to various environmental stresses.…”

Protein pattern, ammonia content, glutamine synthetase activity, lipid peroxidation, superoxide dismutase, catalase, peroxidase and peroxidase isoforms were studied in the leaves and roots of 7-d-old peanut (Arachis hypogaea L. cv. JL-24) seedlings treated by 25, 100 and 250 μM jasmonic acid (JA). SDS-PAGE protein profile of leaves and roots after JA application showed a significant increase in 18, 21, 30, 45, 47 and 97.4 kDa proteins and significant decrease in 22 and 36 kDa proteins. Pathogenesis related PR-18 was specific in leaves at 250 μM JA and PR-21 have cross reacted differently with 21 and 30 kDa proteins in leaves and roots treated by all JA concentrations. Further, the immunoblot analysis with glutamine synthetase, GS-45 antibodies revealed a specific cross reaction with 45 and 47 kDa proteins of both control and JA treated leaves, however, higher at 100 and 250 μM JA treated leaves than control ones. Further, the malondialdehyde (MDA) content significantly increased in leaves and roots treated with JA, indicated membrane damage with JA treatments that led to the generation of peroxidation products. The peroxidase isozymic pattern showed two specific isoforms. Besides, the activities of SOD and catalase were significantly elevated in JA treated leaves.

“…The rice-FAW interaction is a host-herbivore system where frass does not accumulate in close proximity to feeding sites, but falls off from the leaves during herbivory. Jasmonic acid biosynthesis-related lipoxygenase gene (Os-RCI-1) expression is induced by Spodoptera litura feeding in rice and JA treatment (Schaffrath et al 2000;Xu et al 2003).We observed that Os-RCI-1 had higher transcript abundance in frass protein-treated plants only at 24 h after application (Fig. 3a).…”
