“…Although it is claimed that GLY in the soil should not represent a risk to non-target plants (http://www.glyphosate.eu/glyphosate-safetyprofile-non-target-wildlife-and-plants), growing evidence has been showing the opposite for different species, such as barley (Hordeum vulgare L.), willow (Salix miyabeana), saltmarsh bulrush (Bolboschoenus maritimus L.), pea (Pisum sativum L.) and even tomato (S. lycopersicum L.) (Soares et al, 2019a;Gomes et al, 2017;Spormann et al, 2019;Gomes et al, 2016a;Singh et al, 2017;Mateos-Naranjo and Perez-Martin, 2013). In line with this, and corroborating our previous work (Soares et al, 2019a), the exposure of tomato plants to increased concentrations of the herbicide resulted in a substantial alteration of leaf morphology and shape (Fig.…”

This study aimed to assess the toxicity of glyphosate (GLY; 0, 10, 20 and 30 mg kg −1 ) in Solanum lycopersicum L., particularly focusing on the photosynthetic metabolism. By combining ecophysiological, ultrastructural, biochemical and molecular tools, the results revealed that the exposure of tomato plants to GLY led to alterations in leaf water balance regulation [increasing stomatal conductance (g s ) and decreasing water use efficiency (WUE i ) at higher concentrations] and induced slight alterations in the structural integrity of cells, mainly in chloroplasts, accompanied by a loss of cell viability. Moreover, the transcriptional and biochemical control of several photosynthetic-related parameters was reduced upon GLY exposure. However, in vivo chlorophyll fluorometry and IRGA gas-exchange studies revealed that the photosynthetic yield of S. lycopersicum was not repressed by GLY. Overall, GLY impacts cellular and subcellular homeostasis (by affecting chloroplast structure, reducing photosynthetic pigments and inhibiting photosynthetic-related genes transcription), and leaf structure, but is not

“…Recently, our research group, along with other notable studies [ 12 , 40 , 41 , 42 ], has provided important findings concerning GLY non-target phytotoxicity in important plant species, such as barley ( Hordeum vulgare L.) [ 43 ], alfafa ( Medicago sativa L.) [ 44 ] and tomato ( Solanum lycopersicum L.) [ 10 , 45 ]. However, as well as understanding GLY-associated environmental risks, it is also essential to develop new approaches to increase plant tolerance to this herbicide [ 11 ].…”

“…Often, plant responses to abiotic stress factors, including xenobiotic exposure, result in differentially activated/inhibited players. Pro stimulation as a consequence of GLY is a common response of different plant species [ 10 , 11 , 12 , 42 , 44 ]. Accordingly, one of the most recurrent symptoms of GLY at the cellular level is the overaccumulation of this proteinogenic amino acid, whose involvement in stress tolerance has been recurrently highlighted [ 79 ].…”

Silicon Improves the Redox Homeostasis to Alleviate Glyphosate Toxicity in Tomato Plants—Are Nanomaterials Relevant?

Given the widespread use of glyphosate (GLY), this agrochemical is becoming a source of contamination in agricultural soils, affecting non-target plants. Therefore, sustainable strategies to increase crop tolerance to GLY are needed. From this perspective and recalling silicon (Si)’s role in alleviating different abiotic stresses, the main goal of this study was to assess if the foliar application of Si, either as bulk or nano forms, is capable of enhancing Solanum lycopersicum L. tolerance to GLY (10 mg kg−1). After 28 d, GLY-treated plants exhibited growth-related disorders in both shoots and roots, accompanied by an overproduction of superoxide anion (O2•−) and malondialdehyde (MDA) in shoots. Although plants solely exposed to GLY have activated non-enzymatic antioxidant mechanisms (proline, ascorbate and glutathione), a generalized inhibition of the antioxidant enzymes was found, suggesting the occurrence of great redox disturbances. In response to Si or nano-SiO2 co-application, most of GLY phytotoxic effects on growth were prevented, accompanied with a better ROS removal, especially by an upregulation of the main antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX). Overall, results pointed towards the potential of both sources of Si to reduce GLY-induced oxidative stress, without major differences between their efficacy.

“…Glyphosate is a non-selective herbicide and it affects not only weeds but crop plants as well. A number of articles documented that it substantially altered germination and physiological responses of different crops such as pea [4,[6][7][8][9], faba bean and common bean [10], soybean [11], tomato [12,13], maize [14,15], sorghum [10], wheat [6,7], etc. That is why the modulation of the herbicide action by application of ecologically safe plant growth regulators, which are capable to reduce the negative effects of the herbicide on non-target plants, gives rise to interest of fundamental and applied outlook.…”

“…Exogenously applied SA has potential to increase the stress tolerance of economically important crops. SA could regulate, directly or indirectly, the activities of the enzymes of antioxidant defense system and modulate plant responses to various stresses [17][18][19], including those caused by herbicide application [12,20,21]. It can also inhibit the accumulation in plants of different plant protection products such as insecticides, fungicides and herbicides [22][23][24][25].…”

Glyphosate is an extensively used herbicide because of its non-selective action for weed control. Salicylic acid (SA) is a phenolic compound that has the potential to increase plant tolerance to diverse stresses. To test SA ability to modulate plant responses to glyphosate we used young wheat (Triticum aestivum L.) seedlings grown as a water culture. Plants were sprayed with 1 mM SA, and 24 h later with 0.5 mM glyphosate. All measurements were performed 14 days after herbicide treatment. Wheat growth was reduced by glyphosate. Stress markers (proline and malondialdehyde) were significantly increased by glyphosate showing oxidative damages. Incapacity of wheat to cope with the oxidative stress was evidenced by reduction in thiols and phenolics content, accompanied by slight induction of superoxide dismutase and catalase activities. Enhanced activities of peroxidase, glutathione reductase and glutathione-S-transferase were expected to participate in glyphosate detoxification. SA applied alone had no important effects on measured parameters. SA pretreatment decreased stress markers and caused additional amplification of antioxidant defense systems in glyphosate-treated plants. Growth was partially restored in combine-treated plants due to SA application. SA probably triggered antioxidant defense to cope with the herbicide stress.
