TLDR
Data indicate that the inhibition of the plasma membrane H + -ATPase, and more specifically the proton efflux, may be a key step in the signalling pathway leading to the activation of phytoalexin and isoflavone excretion in chickpea seedlings.About:

Elicitor signal transduction leading to production of plant secondary metabolites.
TL;DR: Progress made on several aspects of elicitor signal transduction leading to production of plant secondary metabolites are summarized, including the integration of multiple signaling pathways into or by transcription factors, as well as the linkage of the above signal components in eliciting network through protein phosphorylation and dephosphorylation.
Journal Article
Plant cell elicitation for production of secondary metabolites: A review
TL;DR: The classification of elicitors, their mechanism of action, and applications for the production of phyto-pharmaceuticals from medicinal plants are discussed.

Enhancement of ginsenoside biosynthesis in cell cultures of Panax ginseng by N,N'-dicyclohexylcarbodiimide elicitation.
TL;DR: The results suggest that DCCD may induce the ginsenoside biosynthesis via NO signaling in the P. ginseng cells by up-regulated NO generation and transcription levels of sqs, se and ds.

Intracellular pH signals in the induction of secondary pathways--The case of Eschscholzia californica
Werner Roos,Katrin Viehweger,Batsuch Dordschbal,Brigitte Schumann,Sven Evers,Jörg Steighardt,Wieland Schwartze +6 more
TL;DR: Accumulated data support the existence of a signal path that includes the following steps: links between the above events that connect them within a distinct signal path are substantiated by the phenotypes of transformed cell lines that either display lowered Galpha levels due to antisense transformation or express Galpha-binding antibodies in the cytoplasm.

The Gα Protein Controls a pH-Dependent Signal Path to the Induction of Phytoalexin Biosynthesis in Eschscholzia californica
TL;DR: It is concluded that Gα mediates the stimulation of PLA2 by low elicitor concentrations and that the resulting peak of LPC initiates a transient efflux of vacuolar protons, generating an acidic peak of the cytoplasmic pH that causes the expression of enzymes of phytoalexin production independent of the hypersensitive response.

Stress-Induced Phenylpropanoid Metabolism.
Richard A. Dixon,Nancy L. Paiva +1 more
TL;DR: Limiting discussion to stress-induced phenylpropanoids eliminates few of the structural classes, because many compounds that are constitutive in one plant species or tissue can be induced by various stresses in another species or in another tissue of the same plant.
Journal ArticleDOI
Oxidative burst: an early plant response to pathogen infection
TL;DR: The chemistry of ROS (superoxide radical, hydrogen peroxide and hydroxyl radical) is described and the role of ROS in defence responses is demonstrated, and some important issues are considered, such as: which of the ROS is a major building element of the oxidative burst.

The Plasma Membrane H+-ATPase (A Highly Regulated Enzyme with Multiple Physiological Functions)
Baudouin Michelet,Marc Boutry +1 more
TL;DR: The proton-pump ATPase of the plant plasma membrane acts as a primary transporter by pumping protons out of the cell, thereby creating pH and electrical potential differences across the plasmalemma and promoting more specialized physiological functions.
Journal ArticleDOI
Plant Defense Response to Fungal Pathogens (Activation of Host-Plasma Membrane H+-ATPase by Elicitor-Induced Enzyme Dephosphorylation)
TL;DR: Effects of guanidine nucleotide analogs and mastoparan on the ATPase activity suggested the role of GTP-binding proteins in mediating the putative elicitor-receptor binding, resulting in activation of a phosphatase(s), which in turn stimulates the plasma membrane H+-ATPase by dephosphorylation.
