“…Microbes with such a C−P lyase can only obtain phosphorus from glyphosate or AMPA. 200 Plants can also metabolize glyphosate. 201 Plants can engage in both GOX and C−P lyase-mediated biological activities, but GOX metabolic glyphosate degradation is more common.…”

“…The greater persistence of AMPA than glyphosate in soil may suggest that microorganisms that employ this breakdown route are less prevalent than those with GOX if this is the case for other microbes with C–P lyase.

With a growing global population, agricultural scientists are focusing on crop production management and the creation of new strategies for a higher agricultural output. However, the growth of undesirable plants besides the primary crop poses a significant challenge in agriculture, necessitating the massive application of herbicides to eradicate this problem. Several synthetic herbicides are widely utilized, with glyphosate emerging as a potential molecule for solving this emerging issue; however, it has several environmental and health consequences. Several weed species have evolved resistance to this herbicide, therefore lowering agricultural yield. The persistence of glyphosate residue in the environment, such as in water and soil systems, is due to the misuse of glyphosate in agricultural regions, which causes its percolation into groundwater via the vertical soil profile. As a result, it endangers many nontarget organisms existing in the natural environment, which comprises both soil and water. The current Review aims to provide a systemic analysis of glyphosate, its various effects on the environment, its subsequent impact on human health and animals, which will lead us toward a better understanding of the issues about herbicide usage and aid in managing it wisely, as in the near the future glyphosate market is aiming for a positive forecast until 2035.

“…However, the role of dissolved organic matter (DOM) derived from EWCs (EWC-DOM) remains an open question. Given the above information, this paper (1) investigates the response of citrus seedlings to glyphosate in soil in the presence or absence of EWC-DOM and the potential regulatory capacity of EWC-DOM in this process, (2) explores competent indicators for the level of glyphosate pollution in soil-crop systems, and (3) decodes the role of enzymes in living fruit trees in response to pesticide stress in soil culture systems, hoping to inspire the formulation of strategies to mitigate the negative effects of soil glyphosate on crop growth.…”

Dissolved Organic Matter from Earthworm Casts Restrained the Phytotoxicity of Soil Glyphosate to Citrus (Poncirus trifoliata (L.) Raf.) Plants

A large amount of glyphosate enters the soil at a high frequency, forming “pseudo-persistent” pollutants that, in turn, threaten soil ecological function and crop growth. Earthworm casts (EWCs) are a sound organic alternative to chemical fertilizers to promote crop growth. Dissolved organic matter from EWCs (EWC-DOM) is supposed to be a more mobile and bioavailable fraction. However, the effect of EWC-DOM on the phytotoxicity of glyphosate remains largely unknown. This study examines glyphosate-induced oxidative stress and its impact on antioxidant and detoxification enzymes in citrus plants grown in soils with and/or without EWC-DOM. The results suggest that EWC-DOM could reduce the membrane lipid peroxidation level, thus slowing down the aging of plants in order to maintain stronger resilience, with more active antioxidant enzymes (including SOD, POD, and CAT) and detoxification enzymes (including GST, laccase, CPR, and UGTs) that could effectively remove reactive oxygen species (ROS) caused by glyphosate stress, thereby alleviating the damage of ROS accumulation on plant tissues. Our data indicate that incorporating EWC-DOM should be a sound way to protect citrus plants from the phytotoxicity caused by using glyphosate for orchard weeding. This has major implications for the sustainable and healthy development of citrus production.

The increasing amount of weeds surviving herbicide represents a very serious problem for crop management. The interaction between microbial community of soil and herbicide resistance, along with the potential evolutive consequences, are still poorly known and need to be investigated to better understand the impact on agricultural management. In our study, we analyzed the microbial composition of soils in 32 farms, located in the Northern Italy rice-growing area (Lombardy) with the aim to evaluate the relationship between the microbial composition and the incidence of resistance to acetolactate synthase (ALS) and acetyl-CoA carboxylase (ACCase) inhibiting herbicides in Echinochloa species. We observed that the coverage of weeds survived herbicide treatment was higher than 60% in paddy fields with a low microbial biodiversity and less than 5% in those with a high microbial biodiversity. Fungal communities showed a greater reduction in richness than Bacteria. In soils with a reduced microbial diversity, a significant increase of some bacterial and fungal orders (i.e. Lactobacillales, Malasseziales and Diaporthales) was observed. Interestingly, we identified two different microbial profiles linked to the two conditions: high incidence of herbicide resistance (H-HeR) and low incidence of herbicide resistance (L-HeR). Overall, the results we obtained allow us to make hypotheses on the greater or lesser probability of herbicide resistance occurrence based on the composition of the soil microbiome and especially on the degree of biodiversity of the microbial communities.
