Phytochelatins, the heavy-metal-binding peptides of plants, are synthesized from glutathione by a specific gamma-glutamylcysteine dipeptidyl transpeptidase (phytochelatin synthase).
An enzyme has been discovered and characterized from Silene cucubalus cell suspension cultures that catalyzes the transfer of the gamma-glutamylcysteine dipeptide moiety of glutathione to an acceptorExpand
Jasmonic acid is a signal transducer in elicitor-induced plant cell cultures.
It is shown that endogenous jasmonic acid and its methyl ester accumulate rapidly and transiently after treatment of plant cell suspension cultures of Rauvolfia canescens and Eschscholtzia californica with a yeast elicitor. Expand
Phytochelatins, a class of heavy-metal-binding peptides from plants, are functionally analogous to metallothioneins.
It is shown that all plants tested synthesized phytochelatins upon exposure to heavy metal ions, and no evidence for the occurrence of metallothionein-like proteins was found. Expand
Heavy metal detoxification in higher plants--a review.
The isolation of a Cd(2+)-sensitive cadl mutant of Arabidopsis thaliana, that is deficient in PC synthase, demonstrates conclusively the importance of PC for heavy metal tolerance. Expand
Phytochelatins: The Principal Heavy-Metal Complexing Peptides of Higher Plants
These peptides appear upon induction of plant cells with heavy metals and represent the principal metal-binding activities in the cells and are proposed as phytochelatin for this new class of natural products. Expand
The deoxyxylulose phosphate pathway of terpenoid biosynthesis in plants and microorganisms.
Recent studies have uncovered the existence of an alternative, non-mevalonate pathway for the formation of isopentenyl pyrophosphate and dimethylallyl pyrophosphate, the two building blocks ofExpand
The octadecanoic pathway: signal molecules for the regulation of secondary pathways.
Experiments with synthetic trihomojasmonate demonstrated that beta-oxidation is not a prerequisite for biological activity and that 12-oxophytodienoic acid and derivatives are most likely fully active as signal transducers. Expand
Prenylation of olivetolate by a hemp transferase yields cannabigerolic acid, the precursor of tetrahydrocannabinol
A new enzyme, geranylpyrophosphate:olivetolate geranyltransferase (GOT), the first enzyme in the biosynthesis of cannabinoids could be detected in extracts of young leaves of Cannabis sativa. TheExpand
Signaling in the elicitation process is mediated through the octadecanoid pathway leading to jasmonic acid.
It is demonstrated in this study that cis-jasmonic acid is rapidly synthesized in plant cell cultures of diverse taxonomic origin after challenge with a fungal elicitor preparation. Expand
Chemical Syntheses and Properties of Hydroxycinnamoyl- Coenzyme A Derivatives
The cinnamyol-CoA thiol esters were characterized by their chromatographic behaviour and UV spectra and the molar extinction coefficients of these important intermediates in plant phenylpropane metabolism have been unequivocally determined. Expand
