Glutathione and glucoside conjugation in herbicide selectivity

TLDR
The conjugation of herbicides with glutathione or glucose are frequently species specific reactions that result in herbicide detoxification and selectivity, and the role that these reactions play in the selectivity of specific herbicides is reviewed.
Abstract
The conjugation of herbicides with glutathione or glucose are frequently species specific reactions that result in herbicide detoxification Therefore, glutathione and glucoside conjugation play an important role in herbicide detoxification and selectivity Phase 1 activation reactions are sometimes necessary before glutathione or glucoside conjugation can occur In these cases, the Phase 1 reaction rather than conjugation may be responsible for herbicide selectivity This appears to be particularly true in the metabolism of herbicides to 0-glucoside conjugates The glutathione-S-transferases and glucosyltransferases that catalyze these conjugation reactions, the role that these reactions play in the selectivity of specific herbicides, factors that affect these reactions, and the secondary metabolism of glutathione and glucoside conjugates are reviewed

Glutathione Metabolic Genes Coordinately Respond to Heavy Metals and Jasmonic Acid in Arabidopsis

TL;DR: Feeding experiments suggested that neither oxidative stress, as results from exposure to H2O2, nor oxidized or reduced glutathione levels were responsible for activating transcription of these genes, but Jasmonic acid treatment increased mRNA levels and the capacity forglutathione synthesis but did not alter the glutATHione content in unstressed plants, which supports the idea that the glutathion concentration is controlled at multiple levels.

Pathways and regulation of sulfur metabolism revealed through molecular and genetic studies

TL;DR: This review focuses on recent advances in the field of plant sulfur metabolism and emphasizes areas about which little is known, including transport and recycling/degradation of sulfur compounds.

Detoxification of xenobiotics by plants: chemical modification and vacuolar compartmentation

TL;DR: The vacuolar glutathione-conjugate transporter shows functional similarities with an ATP-binding cassette transporter, the multidrug resistance-associated protein, present in drug-tolerant human cancer cells.

Glycosyltransferases in secondary plant metabolism: tranquilizers and stimulant controllers

TL;DR: This work describes how a large number of glycosyltransferases with broad, rather than narrow, substrate specificity can be constrained in order to avoid interfering with other pathways of primary and secondary metabolism.
Journal ArticleDOI

Pesticide metabolism in plants and microorganisms

TL;DR: Pesticide biotransformation may occur via multistep processes known as metabolism or cometabolism as discussed by the authors, which is not used as an energy source or as a constitutive element of the organism.

Glutathione metabolism and possible biological roles in higher plants

TL;DR: Synthesis of glutathione in plants seems to proceed in the same series of enzyme catalysed reactions observed in animal cells; the pathway ofglutathione may be the same as that of animal cells.

Purification and characterization of corn glutathione S-transferase.

TL;DR: Two glutathione S-transferase activities have been identified and purified from etiolated corn tissue, and both catalyze the formation of a glutathion-herbicide conjugate in vitro when the herbicide alachlor is used as a substrate.

A review of the activity, fate and mode of action of sulfonylurea herbicides

TL;DR: The sulfonylurea herbicides are a relatively new group of compounds which control broad-leaved weeds and some grasses in cereal crops as discussed by the authors, and their mode of action is discussed.

Metabolism of chlorsulfuron by plants: Biological basis for selectivity of a new herbicide for cereals

TL;DR: This metabolite has been characterized as the O -glycoside of chlorsulfuron in which the phenyl ring has undergone hydroxylation followed by conjugation with a carbohydrate moiety.

Biosynthesis of S-(4-ethylamino-6-isopropylamino- 2-s-triazino) glutathione: Partial purification and properties of a glutathione S-transferase from corn☆

TL;DR: In this article, a corn S-transferase was reported to catalyze the conjugation of several substituted 2-chloro-s-triazine herbicides with reduced glutathione.
