“…Pro197 can be substituted by many different types of amino acids in different species, such as Pro197Thr in Bassia scoparia (L.) A. J. Scott (Guttieri et al 1995), Pro197His in Papaver rhoeas L. (Yu et al 2003), Pro197Ser in Bromus japonicus Thunb. (Lan et al 2022) etc. In our case, for MATIN-2, we found Pro197Ser, and for MATIN-4, we detected Pro197Gln, all plants tested were heterozygous.…”

Scentless mayweed (Tripleurospermum inodorum (L.) Sch. Bip.) is a competitive weed in the disturbed and agricultural areas of Europe, including the Czech Republic (Štrobach and Mikulka 2019). This weed is difficult to manage, particularly in cereals such as winter wheat and winter rape (Nadtochii 2009, Reiss et al. 2018. Since this weed germinates at almost the same time to that of the crop and produces high biomass, it significantly affects the yield of these crops (Adamczewski et al. 2014). The prevalence of this weed is mostly due to minimum or no-tillage systems. In general, scentless mayweed is well controlled by the most widely used herbicides in cereals, especially inhibitors of enzyme acetolactate synthase (ALS) such as active ingredients tribenuron, pyroxsulam or florasulam (Majcen et al. 2013, Jursík et al. 2018. Some herbicides, such as carfentrazone, pendimethalin, and growth regulator-inhibiting herbicides, were found to be less effective against this weed. Pre-emergence herbicides containing metazachlor, dimetachlor and pethoxamide usually give the most effective scentless mayweed control in winter rape. In case of control failure or the absence of preemergent treatment, herbicides containing clopyralid, picloram and halauxifen (synthetic auxins) can be applied after emergence during autumn or spring (Jursík et al. 2018).Acetolactate synthase is a vital enzyme involved in the synthesis of the branched-chain amino acids valine, leucine and isoleucine (Duggleby and Pang 2000). Since the first cases of resistance against ALSinhibiting herbicides, there has been a continuous rise

“…Herbicide resistance in B. japonicus was first reported in the United States in 2007 (Heap 2022) and in China in 2022 (Lan et al 2022; Table 1). In both cases, the reported populations were ALS resistant with broad-spectrum cross-resistance patterns.…”

“…In both cases, the reported populations were ALS resistant with broad-spectrum cross-resistance patterns. The population identified in China exhibited a 120-fold increase in flucarbazone-sodium resistance (Lan et al 2022). The DNA sequence analyses of the ALS gene revealed a single nucleotide substitution of CCC to TCC at codon 197, resulting in a Pro-197-Ser mutation.…”

This review summarizes what is currently known about herbicide resistance in Bromus spp. worldwide. Additional information on the biology and genetics of Bromus spp. is provided to further the understanding of resistance evolution and dispersal of the different species. Cases of herbicide resistance have been confirmed in Bromus catharticus Vahl., Bromus commutatus Schrad.; syn. Bromus racemosus L., Bromus diandrus Roth, Bromus japonicus Thunb.; syn. Bromus arvensis L., Bromus madritensis L., Bromus rigidus Roth; syn. Bromus diandrus Roth ssp. diandrus, Bromus rubens L., Bromus secalinus L., Bromus sterilis L., and Bromus tectorum L. in 11 countries. Bromus spp. populations have evolved cross and multiple-resistance to six herbicide sites of action: acetyl-coenzyme A carboxylase, acetolactate synthase, photosystem II, very long-chain fatty acid, 5-enolpyruvylshikimate-3-phosphate synthase, and 4-hydroxyphenylpyruvate dioxygenase inhibitors. Resistance mechanisms varied from target-site to non-target-site or a combination of both. Bromus spp. are generally highly self-pollinated, but outcrossing can occur at low levels in some species. Bromus spp. have different ploidy levels, ranging from diploid (2n = 2x = 14) to duodecaploid (2n = 12x = 84). Herbicide resistance in Bromus spp. is a global issue, and the spread of herbicide resistance alleles primarily occurs via seed-mediated gene flow. However, the transfer of herbicide resistance alleles via pollen-mediated gene flow is possible.

Ammannia auriculata is a troublesome broadleaf weed, widely distributed in the paddy fields of southern China. In this study, 10 biotypes of A. auriculata were sampled from Yangzhou City, China, where the paddy fields were seriously infested with A. auriculata, and their resistance levels to acetolactate synthase (ALS) inhibitor bensulfuron-methyl were determined. The whole-plant response assays showed that nine A. auriculata biotypes were highly resistant (from 16.4- to 183.1-fold) to bensulfuron-methyl in comparison with a susceptible YZ-S biotype, and only one YZ-6 biotype was susceptible. ALS gene sequencing revealed that three ALS gene copies existed in A. auriculata, and four different amino acid substitutions (Pro197-Leu, -Ala, -Ser, and -His) at site 197 in the AaALS1 or 2 genes were found in eight resistant biotypes. In addition, no amino acid mutations in three ALS genes were found in the YZ-3 biotype. These results suggested that target-site mutations or non-target-site resistance mechanisms were involved in tested resistant A. auriculata biotypes. Finally, a cleaved amplified polymorphic sequence (CAPS) marker was identified to rapidly detect the Pro197 mutations in A. auriculata.
