On the specificity of lipid hydroperoxide fragmentation by fatty acid hydroperoxide lyase from Arabidopsis thaliana.

Only registered users can translate articles

Fatty acid hydroperoxide lyase (HPL) is a membrane associated P450 enzyme that cleaves fatty acid hydroperoxides into aldehydes and omega-oxo fatty acids. One of the major products of this reaction is (3Z)-hexenal. It is a constituent of many fresh smelling fruit aromas. For its biotechnological

E-2-hexenal promotes susceptibility to Pseudomonas syringae by activating jasmonic acid pathways in Arabidopsis.

Green leaf volatiles (GLVs) are C6-molecules - alcohols, aldehydes, and esters - produced by plants upon herbivory or during pathogen infection. Exposure to this blend of volatiles induces defense-related responses in neighboring undamaged plants, thus assigning a role to GLVs in regulating plant

Variations in CYP74B2 (hydroperoxide lyase) gene expression differentially affect hexenal signaling in the Columbia and Landsberg erecta ecotypes of Arabidopsis.

Only registered users can translate articles

The CYP74B2 gene in Arabidopsis (Arabidopsis thaliana) ecotype Columbia (Col) contains a 10-nucleotide deletion in its first exon that causes it to code for a truncated protein not containing the P450 signature typical of other CYP74B subfamily members. Compared to CYP74B2 transcripts in the

Identification of a Hexenal Reductase That Modulates the Composition of Green Leaf Volatiles.

Green leaf volatiles (GLVs), including six-carbon (C6) aldehydes, alcohols, and esters, are formed when plant tissues are damaged. GLVs play roles in direct plant defense at wound sites, indirect plant defense via the attraction of herbivore predators, and plant-plant communication. GLV components

Volatile C6-aldehydes and Allo-ocimene activate defense genes and induce resistance against Botrytis cinerea in Arabidopsis thaliana.

Green leafy volatiles or isoprenoids are produced after mechanical wounding or pathogen/herbivore attacks in higher plants. We monitored expression profiles of the genes involved in defense responses upon exposing Arabidopsis thaliana to the volatiles. Among the genes investigated, those known to be

Forward genetic screens identify a role for the mitochondrial HER2 in E-2-hexenal responsiveness.

UNASSIGNED This work adds a new player, HER2, downstream of the perception of E-2-hexenal, a green leaf volatile, and shows that E-2-hexenal specifically changes the redox status of the mitochondria. It is widely accepted that plants produce and respond to green leaf volatiles (GLVs), but the

The Arabidopsis her1 mutant implicates GABA in E-2-hexenal responsiveness.

When wounded or attacked by herbivores or pathogens, plants produce a blend of six-carbon alcohols, aldehydes and esters, known as C6-volatiles. Undamaged plants, when exposed to C6-volatiles, respond by inducing defense-related genes and secondary metabolites, suggesting that C6-volatiles can act

WRKY40 and WRKY6 act downstream of the green leaf volatile E-2-hexenal in Arabidopsis.

Plants are known to be responsive to volatiles, but knowledge about the molecular players involved in transducing their perception remains scarce. We study the response of Arabidopsis thaliana to E-2-hexenal, one of the green leaf volatiles (GLV) that is produced upon wounding, herbivory or

The impact of alteration of polyunsaturated fatty acid levels on C6-aldehyde formation of Arabidopsis thaliana leaves.

Only registered users can translate articles

C6-aldehydes are synthesized via lipoxygenase/hydroperoxide lyase action on polyunsaturated fatty acid (PUFA) substrates in plant leaves. The source pools and subcellular location of the processes are unknown. A close relationship is found between the composition of PUFA and the composition of

Transcriptome analysis of Arabidopsis thaliana treated with green leaf volatiles: possible role of green leaf volatiles as self-made damage-associated molecular patterns.

Only registered users can translate articles

Green leaf volatiles (GLVs), which include C6 aldehydes, alcohols, and their esters, are emitted by damaged plants and are, therefore, thought to be involved in stress responses. However, the effects of GLVs on gene expression are not fully understood. Thus, the aim of the present study was to

Molecular cloning and expression of Arabidopsis fatty acid hydroperoxide lyase.

Fatty acid hydroperoxide lyase (HPOL), an enzyme of the octadecanoid pathway that forms carbon-6 aldehydes such as n-hexanal or (Z)-3-hexenal, was cloned from Arabidopsis thaliana as a full-length cDNA. The HPOL activity obtained by expressing the cDNA in Escherichia coli formed n-hexanal from

The involvement of lipid peroxide-derived aldehydes in aluminum toxicity of tobacco roots.

Only registered users can translate articles

Oxidative injury of the root elongation zone is a primary event in aluminum (Al) toxicity in plants, but the injuring species remain unidentified. We verified the hypothesis that lipid peroxide-derived aldehydes, especially highly electrophilic alpha,beta-unsaturated aldehydes (2-alkenals),

The NADPH:quinone oxidoreductase P1-zeta-crystallin in Arabidopsis catalyzes the alpha,beta-hydrogenation of 2-alkenals: detoxication of the lipid peroxide-derived reactive aldehydes.

P1-zeta-crystallin (P1-ZCr) is an oxidative stress-induced NADPH:quinone oxidoreductase in Arabidopsis thaliana, but its physiological electron acceptors have not been identified. We found that recombinant P1-ZCr catalyzed the reduction of 2-alkenals of carbon chain C(3)-C(9) with NADPH. Among these

Identification of oxidatively modified proteins in salt-stressed Arabidopsis: a carbonyl-targeted proteomics approach.

In plants, environmental stresses cause an increase in the intracellular level of reactive oxygen species (ROS), leading to tissue injury. To obtain biochemical insights into this damage process, we investigated the protein carbonyls formed by ROS or by the lipid peroxide-derived α,β-unsaturated

On the induction of volatile organic compound emissions by plants as consequence of wounding or fluctuations of light and temperature.

Only registered users can translate articles

Among the volatile organic compounds (VOCs) emitted by plants, some are characteristic of stress conditions, but their biosynthesis and the metabolic and environmental control over the emission are still unclear. We performed experiments to clarify whether (1) the emission following wounding can
