BACKGROUND Asia minor bluegrass (Polypogon fugax Nees ex Steud.) is an invasive grass species severely infesting wheat and canola fields in China. In May 2017, a suspected resistant P. fugax population AHHY that survived fenoxaprop‐P‐ethyl applied at its field‐recommended rate was collected from a wheat field in Huaiyuan County, Anhui Province, China. This study aimed to determine the resistance profile of AHHY to acetyl‐CoA carboxylase (ACCase) inhibitors and to investigate its mechanisms of resistance to fenoxaprop. RESULTS Single‐dose testing indicated that the AHHY population had evolved resistance to fenoxaprop. The partial carboxyltransferase domain of ACCase in P. fugax was amplified and compared. Four loci encoding plastidic ACCase were isolated from both the resistant and sensitive individuals. Combining gene sequencing with the derived cleaved amplified polymorphic sequence assay, we found that 100% of the plants of AHHY carried Trp‐1999‐Ser mutation in their ACCase1,1–2 allele. Whole‐plant dose–response bioassay indicated that AHHY was highly resistant to fenoxaprop and pinoxaden (resistance index (RI) ≥ 10) with low resistance to clodinafop‐propargyl, sethoxydim, and clethodim (2 ≤ RI < 5). Pre‐treatment with piperonyl butoxide largely reduced (55%) the weed's resistance to fenoxaprop. Both basal and fenoxaprop‐induced glutathione S‐transferases activities toward 1‐chloro‐2, 4‐dinitrobenzene were significantly higher in resistant plants than in susceptible plants. CONCLUSION This study revealed that P. fugax had multiple alleles encoding plastidic ACCase, and reported for the first time the occurrence of Trp‐1999‐Ser mutation and non‐target‐site resistance in this species. Fenoxaprop resistance in AHHY plants was conferred by target‐site mutation and P450s‐involved enhanced metabolism. © 2019 Society of Chemical Industry

“…In rice, the glucosyltransferase gene was reported to be involved in the glucose conjugation of phenolics and possible quinclorac detoxification [107,108]. A glucosyltransferase was identified and enabled as a potential transcriptional marker for quick diagnosis of metabolic resistance to mesosulfuron in Alopecurus aequalis [18].…”

“…Recent studies on NTSR in many species are generally not fully evaluated (or not at all) because processes that confer NTSR are complex. Either type of mechanism can confer resistance to multiple herbicides; both types of mechanisms can occur in the same population or in the same plant, adding another layer of complexity [18]. Recent NTSR studies sought to elucidate the genetic mechanisms that confer and select resistance through detoxification of xenobiotics, with multi-omics approaches, in species such as Amaranthus palmeri, Conyza bonariensis, E. phyllopogon, E. crus-galli, and E. colona [19][20][21][22][23][24][25].…”

Recurrent Selection by Herbicide Sublethal Dose and Drought Stress Results in Rapid Reduction of Herbicide Sensitivity in Junglerice

et al. 2020

Echinochloa colona (junglerice) is a problematic global weed for many crops, primarily controlled with herbicides. Drought stress alters the overall plant physiology and reduces herbicide efficacy. This research aimed to study the joint effect of drought stress (DS) and recurrent selection with sublethal dose of herbicide on adaptive gene expression and herbicide efficacy on E. colona. Three factors were evaluated: (A) E. colona generation (G0, original population from susceptible standard; G1 and G2, progenies of recurrent selection); (B) herbicide treatment (florpyrauxifen-benzyl, 0.25×; glyphosate, 0.125×; quinclorac, 0.125× the recommended dose; and nontreated check); (C) DS (50% and 100% field capacity). Recurrent exposure to sublethal herbicide dose, combined with drought stress, favors the selection of plants less susceptible to the herbicide. Upregulation of defense (antioxidant) genes (APX: ascorbate peroxidase), herbicide detoxification genes (CYP450 family: cytochrome P450), stress acclimation genes (HSP: heat-shock protein, TPP: trehalose phosphate phosphatase, and TPS: trehalose phosphate synthase), and genes related to herbicide conjugation (UGT: UDP glucosyltransferase) in the G2 population was significant. Recurrent exposure to sublethal herbicide dose under drought stress reduces junglerice sensitivity to herbicide, seemingly due to “imprinted” upregulation of metabolic and protection genes in response to these stresses.

Recurrent Selection with Low Herbicide Rates and Salt Stress Decrease Sensitivity of Echinochloa colona to Imidazolinone

Weeds represent an increasing challenge for crop systems since they have evolved adaptability to adverse environmental conditions, such as salinity stress. Herbicide effectiveness can be altered by the quality of water in which the weed is growing. This research aimed to study the combined effect of salt stress and recurrent selection with a sublethal dose of imidazolinone herbicides in the shifting of the sensitivity of Echinochloa colona (L.) Link (junglerice) to imidazolinone herbicides. This study was divided into two experiments; in experiment I, three recurrent selection cycles were conducted in Pelotas/RS/Brazil with imazapic + imazapyr at 0.125× the field rate; and in experiment II, three recurrent selection cycles were conducted in Fayetteville/AR/USA with imazethapyr, at 0.125× the recommended dose. Salt stress was implemented by irrigation with 120 mM sodium chloride (NaCl) solution. The effective dose for 50% control of the population (ED50) values increased from the field population to the second generation (G2) after recurrent selection with a sublethal dose of imidazolinone combined with salt stress, supporting the hypothesis of reduced susceptibility by the combination of these abiotic factors. Recurrent exposure to a sublethal dose of imazapic + imazapyr or imazethapyr, combined with salt stress, reduced susceptibility of Echinochloa colona (L.) plants to imidazolinone herbicides.
