“…Various responses at the molecular, metabolic, and physiological levels are induced in plants when they undergo insect attack, and these responses contribute to plant resistance to those insects (Van Poecke, 2007;Howe and Schaller, 2008). Such resistance is generically termed induced plant resistance.…”

“…Plants exhibit many types of defenses to insect attack, which are classified into two major classes: constitutive defense and induced defense (Kessler and Baldwin, 2002;Howe and Jander, 2008;Howe and Schaller, 2008). Plant defenses have been well analyzed at the molecular, metabolic, and physiological levels (Van Poecke, 2007;Howe and Schaller, 2008). However, we currently understand only some aspects of plant defenses to herbivore attacks.…”

ORCID IDs: 0000-0002-7563-0918 (H.A.); 0000-0003-0802-6208 (M.Y.H.).Here, we analyzed the interaction between Arabidopsis (Arabidopsis thaliana) and the American serpentine leafminer (Liriomyza trifolii), an important and intractable herbivore of many cultivated plants. We examined the role of the immunity-related plant hormone jasmonate (JA) in the plant response and resistance to leafminer feeding to determine whether JA affects host suitability for leafminers. The expression of marker genes for the JA-dependent plant defense was induced by leafminer feeding on Arabidopsis wild-type plants. Analyses of JA-insensitive coi1-1 mutants suggested the importance of JA in the plant response to leafminer feeding. The JA content of wild-type plants significantly increased after leafminer feeding. Moreover, coi1-1 mutants showed lower feeding resistance against leafminer attack than did wild-type plants. The number of feeding scars caused by inoculated adult leafminers in JA-insensitive coi1-1 mutants was higher than that in wild-type plants. In addition, adults of the following generation appeared only from coi1-1 mutants and not from wild-type plants, suggesting that the loss of the JA-dependent plant defense converted nonhost plants to accessible host plants. Interestingly, the glucosinolate-myrosinase defense system may play at most a minor role in this conversion, indicating that this major antiherbivore defense of Brassica species plants probably does not have a major function in plant resistance to leafminer. Application of JA to wild-type plants before leafminer feeding enhanced feeding resistance in Chinese cabbage (Brassica rapa), tomato (Solanum lycopersicum), and garland chrysanthemum (Chrysanthemum coronarium). Our results indicate that JA plays an important role in the plant response and resistance to leafminers and, in so doing, affects host plant suitability for leafminers.

“…2,6 The main pathways leading to VOC biosynthesis include the mevalonate (MVA) pathway (in the cytosol/endoplasmic reticulum; producing sesquiterpenoids) and the 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway (in plastids; liberating mono-and diterpenoids), the shikimic acid pathway (for phenylpropanoid and benzenoid compounds), and the lipoxygenase/hydroperoxide lyase (LOX/HPL) pathway (for green leaf volatiles [GLVs]), along with the myrosinase-catalyzed degradation of glucosinolates (GSs). 1,[7][8][9][10][11] Evidence shows that the abiotic stress factors may change the photochemical or biochemical processes of the photosynthetic cycle. 2 Therefore, VOC emissions might be influenced by changes in biosynthetic pathways (e.g., terpenoids and GLVs).…”

“…2,12 Existing data also indicate that plants respond to biotic stresses by emitting specific blends of volatiles through plant defensive responses regulated by a signaling network, in which salicylate (SA), jasmonate (JA), and ethylene (ET) play key roles. 8,[13][14][15][16][17] Among the various abiotic factors, temperature is a major environmental stressor that directly affects plant inflorescence development, physiological processes and also influences the evaporation and release of VOCs. 2,18 It has been suggested that the release of plant VOCs is frequently associated to an increase or decrease in temperature.…”

The effect of combined abiotic and biotic factors on plant volatile organic compound (VOC) emissions is poorly understood. This study evaluated the VOC emissions produced by Arabidopsis thaliana (L.) Col-0 subjected to 3 temperature regimes (17, 22, and 27°C) in the presence and absence of Plutella xylostella larvae over 2 time intervals (0-4 and 4-8 h), in comparison to control plants. The analyses of VOCs emitted by Arabidopsis plants were made by headspace solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). It was found that certain volatile groups (e.g., alcohols, ketones, aldehydes, and terpenes) are induced by both single factors (temperature or larval infestation) and combined factors (temperature and larvae interactions), whereas other volatile groups (e.g., isothiocyanates [ITCs] and nitrile) were specific to the experimental conditions. ITCs (mainly 4-methylpentyl isothiocyanate) were emitted from plants subjected to larval infestation at 17 and 27°C after the 2 time intervals. The proportions of sulfides (mainly dimethyl disulfide) and 4-(methylthio) butanenitrile were significantly higher on herbivore-infested plants at 22°C compared to the other treatments. Overall, our findings indicate that changes in all experimental conditions caused significant changes to the VOC emissions of Arabidopsis plants. Therefore, the interaction between temperature and larval feeding may represent an important factor determining the variability of volatile emissions by plants subjected to multiple simultaneous factors.

“…Such tools are most abundantly available for molecular model species such as Arabidopsis and are used to investigate mechanisms of induced defense through a molecular genetic approach (for review, see Van Poecke, 2007). However, Arabidopsis is not the ideal plant for investigating the ecology of insect-plant interactions due to its early-season phenology.…”
