“…However, such resistance has also been identified in populations of at least 12 other weed species (Owen et al, 2012;Ma et al, 2013;Iwakami et al, 2014c; for review, see Preston, 2004;Powles and Yu, 2010;Beckie and Tardif, 2012). A very recent development is the discovery of metabolic resistance to atrazine and 4-hydroxyphenylpyruvate dioxygenaseinhibiting herbicides in Amaranthus tuberculatus (Ma et al, 2013).…”

“…Similarly, cross-resistance was early evident in A. myosuroides populations in the United Kingdom (Moss and Cussans, 1985). Since then, metabolic resistance and cross-resistance have been reported in some other resistant weed species (Coupland et al, 1990;Anderson and Gronwald, 1991;Gimenez-Espinosa et al, 1996;Preston, 1997, 2001;Maneechote et al, 1997;Singh et al, 1998;Fischer et al, 2000b;Veldhuis et al, 2000;Cocker et al, 2001;Fraga and Tasende, 2003;Park et al, 2004;Menendez et al, 2006;Owen et al, 2012;Ahmad-Hamdani et al, 2013;Ma et al, 2013;Iwakami et al, 2014c; for review, see De Prado and Franco, 2004;Preston, 2004;Yuan et al, 2007;Powles and Yu, 2010;Beckie and Tardif, 2012;Yu and Powles, 2014). As most research on metabolic resistance has focused on L. rigidum, A. myosuroides, and E. phyllopogon, we review metabolic resistance and cross-resistance in these three species while recognizing that metabolic resistance also occurs in other weedy species and is an increasingly observed phenomenon.…”

Metabolism-Based Herbicide Resistance and Cross-Resistance in Crop Weeds: A Threat to Herbicide Sustainability and Global Crop Production

Weedy plant species that have evolved resistance to herbicides due to enhanced metabolic capacity to detoxify herbicides (metabolic resistance) are a major issue. Metabolic herbicide resistance in weedy plant species first became evident in the 1980s in Australia (in Lolium rigidum) and the United Kingdom (in Alopecurus myosuroides) and is now increasingly recognized in several crop-weed species as a looming threat to herbicide sustainability and thus world crop production. Metabolic resistance often confers resistance to herbicides of different chemical groups and sites of action and can extend to new herbicide(s). Cytochrome P450 monooxygenase, glycosyl transferase, and glutathione S-transferase are often implicated in herbicide metabolic resistance. However, precise biochemical and molecular genetic elucidation of metabolic resistance had been stalled until recently. Complex cytochrome P450 superfamilies, high genetic diversity in metabolic resistant weedy plant species (especially cross-pollinated species), and the complexity of genetic control of metabolic resistance have all been barriers to advances in understanding metabolic herbicide resistance. However, next-generation sequencing technologies and transcriptome-wide gene expression profiling are now revealing the genes endowing metabolic herbicide resistance in plants. This Update presents an historical review to current understanding of metabolic herbicide resistance evolution in weedy plant species.

“…Non-target-site resistance to ACCase-and ALS-inhibiting herbicides is now recognized to be widespread in several weed species, including A. myosuroides , Bromus rigidus (Owen et al, 2012), and Lolium rigidum (Han et al, 2016). Metabolic resistance is a leading member in NTSR, and it can enhance metabolic capacity of the plant to detoxify herbicides, which reduces the amount of active ingredient of herbicide reaching target site.…”

Alopecurus aequalis Sobol. is a common grass weed, which has become increasingly troublesome to control in China wheat fields. One A. aequalis population, collected from Anhui Province China, was suspected to be resistant to fenoxaprop-P-ethyl and mesosulfuron-methyl. This study aimed to establish the cross-resistance pattern using the purified subpopulation and explore the potential targetsite and non-target-site based resistance mechanisms. Sequencing results showed that a single nucleotide change of ATT to AAT was present in acetyl-CoA carboxylase (ACCase) gene of the resistant (R) plants, resulting in an Ile2041Asn amino acid substitution. Besides, another single nucleotide change of CCC to CGC was present in acetolactate synthase (ALS) gene of the R plants, resulting in a Pro197Arg amino acid substitution. The homozygous resistant plants were isolated and the seeds were used in whole-plant herbicide bioassays. Compared with the susceptible (S) population, R population displayed high level resistance to fenoxaprop-P-ethyl and mesosulfuronmethyl. Cross resistance patterns showed that the R population was highly resistant to clodinafop-propargyl, moderately resistant to pyroxsulam and flucarbazoncsodium, lowly resistant to pinoxaden, and susceptible to tralkoxydim, sethoxydim, and isoproturon. The pretreatment of piperonyl butoxide reduced the 50% growth reduction (GR50) value of fenoxaprop-P-ethyl, suggesting that target-site resistance and non-target-site resistance mechanisms were both present in fenoxaprop-P-ethyl-resistance of A. aequalis. This is the first report of ACCase Ile2041Asn and ALS Pro197Arg mutation in A. aequalis.
