“…These different accumulation patterns suggest the existence of different regulatory mechanisms for their synthesis or different metabolic fluxes as well as different physiological roles during senescence in plants. Reports suggesting that indole-GLSs, especially 1MI3M and 4MI3M, were more responsive to induction than Met-GLSs by wounding, insects, and JAs (Bodnaryk, 1992(Bodnaryk, , 1994Doughty et al, 1995) fit with the high accumulation of 1MI3M and 4MI3M in senescent leaves, where cellular damage and JA accumulation occur (BuchananWollaston et al, 2003). Although the temporal accumulation patterns of Met-GLSs and indole-GLSs were different, they were similarly distributed within a single leaf.…”

Developmental senescence is a coordinated physiological process in plants and is critical for nutrient redistribution from senescing leaves to newly formed sink organs, including young leaves and developing seeds. Progress has been made concerning the genes involved and the regulatory networks controlling senescence. The resulting complex metabolome changes during senescence have not been investigated in detail yet. Therefore, we conducted a comprehensive profiling of metabolites, including pigments, lipids, sugars, amino acids, organic acids, nutrient ions, and secondary metabolites, and determined approximately 260 metabolites at distinct stages in leaves and siliques during senescence in Arabidopsis (Arabidopsis thaliana). This provided an extensive catalog of metabolites and their spatiotemporal cobehavior with progressing senescence. Comparison with silique data provides clues to source-sink relations. Furthermore, we analyzed the metabolite distribution within single leaves along the basipetal sink-source transition trajectory during senescence. Ceramides, lysolipids, aromatic amino acids, branched chain amino acids, and stressinduced amino acids accumulated, and an imbalance of asparagine/aspartate, glutamate/glutamine, and nutrient ions in the tip region of leaves was detected. Furthermore, the spatiotemporal distribution of tricarboxylic acid cycle intermediates was already changed in the presenescent leaves, and glucosinolates, raffinose, and galactinol accumulated in the base region of leaves with preceding senescence. These results are discussed in the context of current models of the metabolic shifts occurring during developmental and environmentally induced senescence. As senescence processes are correlated to crop yield, the metabolome data and the approach provided here can serve as a blueprint for the analysis of traits and conditions linking crop yield and senescence.

cis-Jasmone, or (Z)-jasmone, is well known as a component of plant volatiles, and its release can be induced by damage, for example during insect herbivory. Using the olfactory system of the lettuce aphid to investigate volatiles from plants avoided by this insect, (Z)-jasmone was found to be electrophysiologically active and also to be repellent in laboratory choice tests. In field studies, repellency from traps was demonstrated for the damson-hop aphid, and with cereal aphids numbers were reduced in plots of winter wheat treated with (Z)-jasmone. In contrast, attractant activity was found in laboratory and wind tunnel tests for insects acting antagonistically to aphids, namely the seven-spot ladybird and an aphid parasitoid. When applied in the vapor phase to intact bean plants, (Z)-jasmone induced the production of volatile compounds, including the monoterpene (E)-␤-ocimene, which affect plant defense, for example by stimulating the activity of parasitic insects. These plants were more attractive to the aphid parasitoid in the wind tunnel when tested 48 h after exposure to (Z)-jasmone had ceased. This possible signaling role of (Z)-jasmone is qualitatively different from that of the biosynthetically related methyl jasmonate and gives a long-lasting effect after removal of the stimulus. Differential display was used to compare mRNA populations in bean leaves exposed to the vapor of (Z)-jasmone and methyl jasmonate. One differentially displayed fragment was cloned and shown by Northern blotting to be up-regulated in leaf tissue by (Z)-jasmone. This sequence was identified by homology as being derived from a gene encoding an ␣-tubulin isoform.

“…A possible reason for this pattern could be an increase in the secondary plant metabolites and especially the glucosinolates which are characteristic of the Brassicaceae. Herbivory, mechanical damage (Porter et al, 1991;Koritsas et al, 1991;Birch et al, 1992;Bartlet et al, 1999), other forms of stress, and abiotic elicitors (Doughty et al, 1995) are known to induce glucosinolate production in leaves as part of the plants stress response. Ozone is known to induce increased levels of secondary plant metabolites (Bolsinger et al, 1991;Trumble et al, 1987) although this is not always the case (Kainulainen et al, 1994(Kainulainen et al, , 1998.…”

Elevated levels of tropospheric ozone and their effects on plants have been studied for a great number of years. Ozone is a gaseous pollutant and acts as a phytotoxin. Even though ozone is known to change the physiology of plants, little attention has been given to the indirect effects of ozone on plant-insect interactions. This paper addresses this question by investigating the interactive effects of ozone and plant genotype on insects. Lines of rapid-cycling Brassica rapa (L.) selected for their contrasting sensitivity to ozone and Pieris brassicae (L.) (Lepidoptera: Pieridae) were used as a model system. The effect of differences in ozone sensitivity and ozone fumigation on the plant's carbon and nitrogen pools, the feeding preference, and behaviour of P. brassicae larvae were investigated. The results show that the plant's susceptibility to ozone interacts in a complex way with ozone induced alterations in the suitability of the plant for the insect. Only the larval performance on the sensitive line was affected by ozone exposure. Biochemical changes in the resistant B. rapa line made the plant a better food source for the insects, since the digestibility of this plant was significantly higher than that of the sensitive line, and the larvae pupated more quickly and were heavier.
