In response to insect feeding, corn plants (Zea mays cv. Delprim) release elevated levels of volatile organic compounds (VOCs), including the C6-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… Expand
Volatile C6-aldehydes and Allo-ocimene activate defense genes and induce resistance against Botrytis cinerea in Arabidopsis thaliana.
TLDR
It was suggested that both the jasmonate-dependent and -independent pathways were operative upon perception of the volatiles, while the ETR1-dependent pathway was not directly involved. Expand
Metabolomics Reveal Induction of ROS Production and Glycosylation Events in Wheat Upon Exposure to the Green Leaf Volatile Z-3-Hexenyl Acetate
TLDR
Data indicate that GLV Z-3-HAC is taken up by leaves and incites oxidative stress, which subsequently results in the modulation of the phenylpropanoid pathway and an induction of glycosylation processes. Expand
Characterization of a BAHD acyltransferase responsible for producing the green leaf volatile (Z)-3-hexen-1-yl acetate in Arabidopsis thaliana.
TLDR
A member of the BAHD acyltransferase gene family At3g03480 is characterized which catalyzes the formation of (Z)-3-hexen-1-yl acetate from acetyl-CoA and (Z), which has the ability to accept several medium-chain-length aliphatic and benzyl-derived alcohols, but has highest catalytic efficiency with (Z). Expand
Conversion of volatile alcohols into their glucosides in Arabidopsis
TLDR
Exposure of tomato plants to volatile chemicals emitted from common cutworm (Spodoptera litura)-infested conspecifics led to accumulation of the glycoside, (Z)-3-hexenyl vicianoside, suggesting that Arabidopsis might convert a broad range of volatile alcohols into the corresponding glucosides. Expand
The role of E-2-hexenal and γ-amino butyric acid in plant defense responses
It is widely accepted that plants produce and respond to green leaf volatiles (GLVs), but the molecular components involved in transducing their perception are largely unknown. We have previouslyExpand
Enhanced transcriptome responses in herbivore-infested tea plants by the green leaf volatile (Z)-3-hexenol
TLDR
Green leaf volatiles (GLVs) play a vital role in enhancing herbivore-associated defense responses, but the mechanism by which they precisely regulate such responses is not well understood, so RNA-Sequencing was employed to investigate the effect of z3HOL on transcriptome responses to TG in tea plants. Expand
Priming defense genes and metabolites in hybrid poplar by the green leaf volatile cis-3-hexenyl acetate.
TLDR
Woody plants can detect and use z3HAC as a signal to prime defenses before actually experiencing damage, and GLVs may have important ecological functions in arboreal ecosystems. Expand
E-2-hexenal promotes susceptibility to Pseudomonas syringae by activating jasmonic acid pathways in Arabidopsis
TLDR
Green leaf volatiles may have multiple effects on plant–pathogen interactions, in this case reducing resistance to Pseudomonas syringae via JA and ORA59. Expand
Plant–Plant Signaling: Ethylene Synergizes Volatile Emission In Zea mays Induced by Exposure to (Z)-3-Hexen-1-ol
TLDR
It is demonstrated that HI-VOC induction by Z-3-ol is synergized by the phytohormone ethylene, and it is suggested that ethylene plays a synergistic role in plant–plant signaling mediated by green leaf volatiles. Expand
Distinct Roles of Jasmonates and Aldehydes in Plant-Defense Responses
TLDR
This study conclusively establishes that jasmonates and C6-aldehydes play distinct roles in plant defense responses, and characterized the volatiles emitted by these plants upon aphid infestation or mechanical wounding and identified hexenyl acetate as the predominant compound in these volatile blends.

C6-volatiles derived from the lipoxygenase pathway induce a subset of defense-related genes.
TLDR
Trans-2-hexenal induction closely mimics the group of genes induced by methyl jasmonate (MeJA), but the inductive effect seemed to be limited to C6-related volatiles, as C8-, C9- and other related volatile did not induce LOX mRNA levels. Expand
Formation of lipoxygenase-pathway-derived aldehydes in barley leaves upon methyl jasmonate treatment.
TLDR
The first proof that (2E)-4-hydroxy-2-hexenal is formed in plants under physiological conditions is formed, thereby raising the question of whether it functions in the degradation of chloroplast membrane constituents, which takes place after methyl jasmonate treatment. Expand
An herbivore elicitor activates the gene for indole emission in maize.
TLDR
Gene-sequence analysis indicates that Igl and Bx1 are evolutionarily related to the tryptophan synthase alpha subunit, and IGL's enzymatic properties are similar to BX1, a maize enzyme that serves as the entry point to the secondary defense metabolites DIBOA and DIMBOA. Expand
Nitrogen Deficiency Increases Volicitin-Induced Volatile Emission, Jasmonic Acid Accumulation, and Ethylene Sensitivity in Maize1
TLDR
N availability influences plant responses to insect-derived elicitors through changes in E sensitivity and E-independent JA kinetics, and alters volicitin-E interactions. Expand
Differential induction of plant volatile biosynthesis in the lima bean by early and late intermediates of the octadecanoid-signaling pathway.
TLDR
The differential induction of volatiles resembles previous findings on signal transduction in mechanically stimulated tendrils of Bryonia dioica. Expand
EXOGENOUS METHYL JASMONATE INDUCES VOLATILE EMISSIONS IN COTTON PLANTS
TLDR
The results indicate that treatment of cotton with MeJA can directly and systemically induce the emission of volatiles that may serve as odor cues in the host-search behavior of natural enemies. Expand
Volatile Products of the Lipoxygenase Pathway Evolved from Phaseolus vulgaris (L.) Leaves Inoculated with Pseudomonas syringae pv phaseolicola
TLDR
Results demonstrate that during plant defense responses against microbial attack, several lipid-derived compounds are produced by the plant, some of which possess antimicrobial activity and conceivably are involved in plant disease resistance. Expand
Involvement of Jasmonate-signaling pathway in the herbivore-induced rice plant defense
TLDR
The expression patterns of eight defenserelated genes in the herbivore-infested and jasmonatetreated rice leaves were analyzed using RT-PCR and indicated that in rice leaves, the JA-related signaling pathway was involved in the S. litura-induced chemical defense. Expand
Expression of allene oxide synthase determines defense gene activation in tomato.
TLDR
The kinetics of AOS induction in response to wounding and elicitors, in parallel with that of the wound-inducible PIN II (proteinase inhibitor II) gene, are examined and an updated model for defense gene activation in tomato is proposed. Expand
C6-Green leaf volatiles trigger local and systemic VOC emissions in tomato.
TLDR
Labeling studies showed that de novo synthesis was not required for monoterpene or sesquiterpene release immediately following chemical treatment or insect feeding, and comparative measurements were made between aldehyde doses applied to the plant and levels naturally released from leaves with insect damage.
