“…Instances of multiple resistance to two SOAs include resistance to ACCase and ALS inhibitors (Bobadilla et al 2021;Chandi et al 2011;Kuk et al 2000Kuk et al , 2008Rauch et al 2010;Singh et al 2020), ACCase and EPSPS inhibitors (Bobadilla et al 2021;Dickson et al 2011), ALS and EPSPS inhibitors (Bobadilla et al 2021;Henckes et al 2019), and EPSPS and glutamine synthetase inhibitors (Avila-Garcia and Mallory-Smith 2011; Fernández et al 2017;Karn et al 2018;Kurata et al 2017). Italian ryegrass populations with resistance to three herbicide SOAs have been confirmed (Bobadilla et al 2021;Brunharo and Hanson 2018;Ghanizadeh et al 2015;Liu et al 2014Liu et al , 2016Rauch et al 2010;Singh et al 2020;Vázquez-García et al 2020a;Tehranchian et al 2018). Italian ryegrass populations with resistance to four herbicide SOAs include resistance to ACCase, ALS, PS II, and VLCFA inhibitors (Bobadilla et al 2021;Liu et al 2016); ACCase, ALS, EPSPS, and PS II inhibitors (Tehranchian et al 2019); and ALS, EPSPS, PS II, and VLCFA inhibitors (Bobadilla et al 2021).…”

The objective of this paper was to review the reproductive biology, herbicide-resistant (HR) biotypes, pollen-mediated gene flow (PMGF), and potential for transfer of alleles from HR to susceptible grass weeds including barnyardgrass, creeping bentgrass, Italian ryegrass, johnsongrass, rigid (annual) ryegrass, and wild oats. The widespread occurrence of HR grass weeds is at least partly due to PMGF, particularly in obligate outcrossing species such as rigid ryegrass. Creeping bentgrass, a wind-pollinated turfgrass species, can efficiently disseminate herbicide resistance alleles via PMGF and movement of seeds and stolons. The genus Agrostis contains about 200 species, many of which are sexually compatible and produce naturally occurring hybrids as well as producing hybrids with species in the genus Polypogon. The self-incompatibility, extremely high outcrossing rate, and wind pollination in Italian ryegrass clearly point to PMGF as a major mechanism by which herbicide resistance alleles can spread across agricultural landscapes, resulting in abundant genetic variation within populations and low genetic differentiation among populations. Italian ryegrass can readily hybridize with perennial ryegrass and rigid ryegrass due to their similarity in chromosome numbers (2n=14), resulting in interspecific gene exchange. Johnsongrass, barnyardgrass, and wild oats are self-pollinated species, so the potential for PMGF is relatively low and limited to short distances; however, seeds can easily shatter upon maturity before crop harvest, leading to wider dispersal. The occurrence of PMGF in reviewed grass weed species, even at a low rate is greater than that of spontaneous mutations conferring herbicide resistance in weeds and thus can contribute to the spread of herbicide resistance alleles. This review indicates that the transfer of herbicide resistance alleles occurs under field conditions at varying levels depending on the grass weed species.

“…Introducing a C2186R substitution in the rice ACCase gene via ABEs resulted in the production of haloxyfop-R-methyl-tolerant rice strains [135] (Table S1). Other amino acid substitutions in ACCase confer resistance to rice haloxyfop, such as P1927F and W2125C, also identified through CRISPR-based screens [136,137]. In addition, editing PPO [138], EPSPS [139,140], TubA2 [127], and SF3B1 [141] has been reported to afford resistance to butafenacil, glyphosate, trifluralin, and herboxidiene (GEX1A) Other amino acid substitutions in ACCase confer resistance to rice haloxyfop, such as P1927F and W2125C, also identified through CRISPR-based screens [138,139].…”

“…ACCase is a key enzyme in lipid biosynthesis. It represents the site of action for several commercially important herbicides, such as those of the aromatic phenoxy propionate (APP) class and the cyclohexanone (CHD) class [136].

The clustered regularly interspaced short palindromic repeats (CRISPR)/associated protein 9 system (Cas9) has been used at length to optimize multiple aspects of germplasm resources. However, large-scale genomic research has indicated that novel variations in crop plants are attributed to single-nucleotide polymorphisms (SNPs). Therefore, substituting single bases into a plant genome may produce desirable traits. Gene editing by CRISPR/Cas9 techniques frequently results in insertions–deletions (indels). Base editing allows precise single-nucleotide changes in the genome in the absence of double-strand breaks (DSBs) and donor repair templates (DRTs). Therefore, BEs have provided a new way of thinking about genome editing, and base editing techniques are currently being utilized to edit the genomes of many different organisms. As traditional breeding techniques and modern molecular breeding technologies complement each other, various genome editing technologies have emerged. How to realize the greater potential of BE applications is the question we need to consider. Here, we explain various base editings such as CBEs, ABEs, and CGBEs. In addition, the latest applications of base editing technologies in agriculture are summarized, including crop yield, quality, disease, and herbicide resistance. Finally, the challenges and future prospects of base editing technologies are presented. The aim is to provide a comprehensive overview of the application of BE in crop breeding to further improve BE and make the most of its value.

“…On a chemical basis, the only way to control these biotypes at the seedling stage is the use of ACCase-inhibiting herbicides (Group 1, HRAC legacy group A), such as propaquizafop, which implies that the selection pressure on this SoA will be very high. In fact, resistance to ACCase inhibitors is the most common case in European winter cereals for L. rigidum [ 2 ], stressing the facility to evolve resistance to this SoA in these species [ 21 ]. The evolution of multiple herbicide resistance with respect to glyphosate, ACCase inhibitors, and other SoAs (oxyfluorfen and ALS inhibitors) is expected in Mediterranean countries such as Spain.…”

Herbicide-resistant weeds currently challenge sustainable food production in almost all cropping systems in Europe. Herbicide resistance is increasing, and some European countries are among the most affected globally, such as Spain and France. This situation is worsening not only due to herbicide use restrictions but also due to climate change, rendering Mediterranean countries such as Spain particularly susceptible. Therefore, focus should be aimed at preventive measures, which include those not only based on integrated weed management strategies but also based on a very good knowledge of the biology and ecology of each weed species. The main objective of this review is to provide an overview of potential future herbicide-resistant cases that can evolve in the near future in Europe. We use Spain as the case study, as it is the most affected country in Europe and because it is at risk due to global warming. For different resistant cases detailed on a crop basis, adequate prevention and management measures will be provided in order to avoid resistance evolution relative to the sites of action that are most likely to generate resistant biotypes due to expected high selection pressures.
