“…4,12 An intriguing and potentially related initiator of NTSR was recently proposed: microbial plant endophytes that either directly metabolize xenobiotics or prime host plant stress responses that include NTSR. 13 When exposed to sublethal herbicide doses by improper applications or environmental constraints, susceptible plants respond in much the same as they do to other abiotic stresses (reviewed in Alberto et al 14 ). Stress resulting from abiotic sources including several herbicides 15,16 induces rapid ROS generation, which in turn impacts multiple pathways and cellular components.…”

Herbicide-resistant weeds, especially those with resistance to multiple herbicides, represent a growing worldwide threat to agriculture and food security. Natural selection for resistant genotypes may act on standing genetic variation, or on a genetic and physiological background that is fundamentally altered because of stress responses to sublethal herbicide exposure. Stress-induced changes include DNA mutations, epigenetic alterations, transcriptional remodeling, and protein modifications, all of which can lead to herbicide resistance and a wide range of pleiotropic effects. Resistance selected in this manner is termed systemic acquired herbicide resistance, and the associated pleiotropic effects are manifested as a suite of constitutive transcriptional and post-translational changes related to biotic and abiotic stress adaptation, representing the evolutionary signature of selection. This phenotype is being investigated in two multiple herbicide-resistant populations of the hexaploid, self-pollinating weedy monocot Avena fatua that display such changes as well as constitutive reductions in certain heat shock proteins and their transcripts, which are well known as global regulators of diverse stress adaptation pathways. Herbicide-resistant populations of most weedy plant species exhibit pleiotropic effects, and their association with resistance genes presents a fertile area of investigation. This review proposes that more detailed studies of resistant A. fatua and other species through the lens of plant evolution under stress will inform improved resistant weed prevention and management strategies. © 2018 Society of Chemical Industry.

“…Herbicides are obviously designed to control weeds, but they can also merely cause injury, often due to sublethal dosages (improper applications or equipment problems), adverse environmental conditions that reduce efficacy, or delayed applications on older, more tolerant plants . Under these conditions, susceptible plants respond much the same as they do to other abiotic stresses . For example, suites of genes and enzymes of redox maintenance, xenobiotic metabolism and other protective pathways are recruited, likely as a result of signal transduction changes involving abiotic stress‐specific and other transcription factors (TFs).…”

Repeated exposure to heat, cold, salt or other abiotic stresses can lead to systemic acquired acclimation (SAA), in which plants evolve enhanced stress resistance due to constitutive, enhanced expression of the genes noted above and others.…”

The extent of residual contaminations of pesticides through drift, run-off and leaching is a potential threat to non-target plant communities. Arabidopsis thaliana responds to low doses of the herbicide atrazine, and of its degradation products, desethylatrazine and hydroxyatrazine, not only in the long term, but also under conditions of short-term exposure. In order to investigate underlying molecular mechanisms of low-dose responses and to decipher commonalities and specificities between different chemical treatments, parallel transcriptomic studies of the early effects of the atrazine-desethylatrazine-hydroxyatrazine chemical series were undertaken using whole-genome microarrays. All of the triazines under study produced coordinated and specific changes in gene expression. Hydroxyatrazine-responsive genes were mainly linked to root development, whereas atrazine and desethylatrazine mostly affected molecular signaling networks implicated in stress and hormone responses. Analysis of signaling-related genes, promoter sites and shared-function interaction networks highlighted the involvement of energy-, stress-, abscisic acid- and cytokinin-regulated processes, and emphasized the importance of cold-, heat- and drought-related signaling in the perception of low doses of triazines. These links between low-dose xenobiotic impacts and stress-hormone crosstalk pathways give novel insights into plant-pesticide interactions and plant-pollution interactions that are essential for toxicity evaluation in the context of environmental risk assessment.
