“…Originally, it was inferred that safeners only induce detoxifying enzymes in large grained cereals (Davies and Caseley 1999). However, recent studies have shown that safeners also induce xenome enzymes, notably GSTs, in wild grasses (Del Buono et al 2007), including problem weed species (Cummins et al 2009). Various theories have been expounded as to the mode of action of safeners, with a respective binding protein apparently isolated from maize (Scott-Craig et al 1998).…”

In attempting to understand the mechanisms by which plants process synthetic compounds we have developed the concept of the 'Xenome', which we define as 'the biosystem responsible for the detection, transport and detoxification of xenobiotics.' In particular the last 10 years have given us unprecedented insights into the proteins responsible for the metabolism and transport of xenobiotics within plant cells and how these systems are regulated. In this review we identify recent advances in our understanding of the xenome and its role in the detoxification and processing of pollutants and pesticides. In particular, we focus on the role of the phase 1 (oxidoreductase/ hydrolytic), phase 2 (bioconjugation), phase 3 (transport) and phase 4 (metabolic recycling) stages of xenobiotic metabolism and the biosensing systems which control their expression. Ultimately, by understanding the capability of the plant xenome to detoxify xenobiotics, we may be able to predict the likely fate and environmental risk of new synthetic compounds entering the environment and food chain.

“…Neste sentido, a avaliação de múltiplos protetores é limitada devido à indisponibilidade de vários compostos que possam ocasionar resultados promissores em determinadas espécies. Por exemplo, o protetor benoxacor induz enzimas GST (glutationa S transferase) em Festuca arundinacea, favorecendo a metabolização do compostos 1-chloro-2,4-dinitrobenzene (DEL BUONO et al, 2007). Este mesmo protetor proporciona seletividade ao herbicida terbutilazine em milho (SCARPONI & DEL BUONO, 2005).…”

“…Assim sendo, o efeito dos protetores pode ser diferenciado quando aplicado em pré ou em pós-emergência como avaliado neste estudo, ou até mesmo quando utilizado em mistura com a semente da planta cultivada a ser protegida. A especificidade da associação protetor, herbicida, planta daninha, planta cultivada, e a determinadas partes da planta está relacionada ao mecanismo de ação de cada protetor que é atribuído genericamente a participação de enzimas do grupo das citocromo P450 monoxigenases (P450), GST e ATP binding-cassete (ABC) (DEL BUONO et al, 2007). O aumento da atividade de GST em Festuca arundinacea foi obtido em resposta aos protetores benoxacor, cloquintocet-mexyl, fenchlorazol-ethyl, fenclorim, fluxofenim e oxabetrinil em mistura com os compostos 1-chloro-2,4-dinitrobenzene (CDNB), terbuthylazine e butachlor (SCARPONI & DEL BUONO, 2009).…”

“…An atrazine-resistant biotype of Abutilon theophrasti was reported to have 4-fold higher GST activities toward the herbicide than those found in the susceptible biotype [77]. The role of GSTs in the selectivity of chloroacetanilide herbicides has been well described in numerous monocot and dicot weed species [78][79][80][81][82][83].…”

The metabolic detoxication/bioactivation pathways, the levels and activity of enzymes, and endogenous cofactors mediating these reactions in crops have been well documented; however, much less evidence has been accumulated in weed species. The herbicide metabolism as a selectivity factor is summarized with special attention to acetyl-CoA carboxylases (ACCase)-inhibiting aryloxyphenoxypropionate, protoporphyrinogen IX oxidase (PPO) inhibitor, carotenoid biosynthesis inhibitor clomazone, and acetolactate synthase (ALS) inhibitor imidazolinone and sulfonylurea herbicides in various weed species. The metabolism-based herbicide resistance related to these herbicide classes is also discussed along with the role and level of metabolizing enzymes and cofactors in weed species.
