Arachidonic acid-related elicitors of the hypersensitive response in potato and enhancement of their activities by glucans from Phytophthora infestans (Mont.) deBary.

Logi sisse
The dose response for elicitation of the hypersensitive reaction in potato tuber discs by arachidonic acid (AA) suggested saturation at higher concentrations. Glucans from Phytophthora infestans, inactive themselves as elicitors of the hypersensitive reaction, enhanced sesquiterpene accumulation and
Inhibition of phytoalexin synthesis in arachidonic Acid-stressed potato tissue by inhibitors of lipoxygenase and cyanide-resistant respiration.

Arachidonic acid-stressed potato tuber discs synthesized the phytoalexin rishitin. This synthesis was inhibited by salicylhydroxamic acid (SHAM), and to a lesser extent by tetraethylthiuram disulfide (disulfiram). Disulfiram was less effective apparently because it was inactivated in the tuber
Differential accumulation of potato tuber mRNAs during the hypersensitive response induced by arachidonic acid elicitor.

Accumulation of messenger RNAs in potato tuber discs was analysed during the hypersensitive response induced by treatment with the biotic elicitor arachidonic acid. In vitro translation of polysomal poly(A)(+) RNAs indicated that the accumulation of some sixteen mRNAs varied following treatment with

The oxidative burst has been suggested to be a primary event responsible for triggering the cascade of defense responses in various plant species against infection with avirulent pathogens or pathogen-derived elicitors. The molecular mechanisms of rapid production of active oxygen species (AOS),
Factors affecting the elicitation of sesquiterpenoid phytoalexin accumulation by eicosapentaenoic and arachidonic acids in potato.

Eicosapentaenoic and arachidonic acids in extracts of Phytophthora infestans mycelium were identified as the most active elicitors of sesquiterpenoid phytoalexin accumulation in potato tuber slices. These fatty acids were found free or esterified in all fractions with elicitor activity including
Involvement of de Novo Protein Synthesis, Protein Kinase, Extracellular Ca2+, and Lipoxygenase in Arachidonic Acid Induction of 3-Hydroxy-3-Methylglutaryl Coenzyme A Reductase Genes and Isoprenoid Accumulation in Potato (Solanum tuberosum L.).

The hypothesis that arachidonic acid (AA) induction of sesquiterpene accumulation and browning in potato (Solanum tuberosum) is mediated by a lipoxygenase metabolite of AA was tested using lipoxygenase inhibitors. Salicylhydroxamic acid (SHAM) and 3-amino-1-(3-trifluoromethylphenyl)-2-pyrazoline

Potato (Solanum tuberosum L.) tubers were treated with various concentrations (10(-9) to 10(-4) M) of the biogenic elicitor arachidonic acid during the period of storage (from October to July). The data showed that the resistance-inducing concentration of arachidonic acid was 10(-6) M in autumn and

The activity of lipoxygenase (LOX) in aged potato tuber discs increased by almost 2-fold following treatment of the discs with the fungal elicitor arachidonic acid (AA). Enzyme activity increased above that in untreated discs within 30 min after AA treatment, peaked at 1 to 3 h, and returned to near

Induction of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is essential for the biosynthesis of sesquiterpenoid phytoalexins and steroid derivatives in Solanaceous plants following stresses imposed by wounding and pathogen infection. To better understand this complex step in
Lipid-derived signals that discriminate wound- and pathogen-responsive isoprenoid pathways in plants: methyl jasmonate and the fungal elicitor arachidonic acid induce different 3-hydroxy-3-methylglutaryl-coenzyme A reductase genes and antimicrobial isoprenoids in Solanum tuberosum L.

Mycelial extracts from Phytophthora infestans caused necrosis and elicited the accumulation of antimicrobial stress metabolites in potato tubers. A portion of the material with elicitor activity could be extracted from the mycelium by a mixture of chloroform and methanol. The most active elicitors

We have isolated a full length 5-LOX cDNA clone from potato cDNA library using degenerate primers designed from conserved sequences of LOXs. Sequence analysis and comparison of the deduced amino acid sequence revealed high homology to other plant LOXs. We have expressed the cDNA in Escherichia coli
