Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches

Environment International, Journal Year: 2025, Volume and Issue: 195, P. 109257 - 109257

Published: Jan. 1, 2025

Micro-and-nano plastics (MNPs) are pervasive in terrestrial ecosystems and represent an increasing threat to plant health; however, the mechanisms underlying their phytotoxicity remain inadequately understood. MNPs can infiltrate plants through roots or leaves, causing a range of toxic effects, including inhibiting water nutrient uptake, reducing seed germination rates, impeding photosynthesis, resulting oxidative damage within system. The effects complex influenced by various factors size, shape, functional groups, concentration. Recent advancements omics technologies such as proteomics, metabolomics, transcriptomics, microbiomics, coupled with emerging like 4D omics, phenomics, spatial single-cell offer unprecedented insight into physiological, molecular, cellular responses exposure. This literature review synthesizes current findings regarding MNPs-induced phytotoxicity, emphasizing alterations gene expression, protein synthesis, metabolic pathways, physiological disruptions revealed analyses. We summarize how interact structures, disrupt processes, induce stress, ultimately affecting growth productivity. Furthermore, we have identified critical knowledge gaps proposed future research directions, highlighting necessity for integrative studies elucidate pathways toxicity plants. In conclusion, this underscores potential approaches MNPs-phytotoxicity develop strategies mitigating environmental impact on health.

Comparative effects of biocontrol agent and pathogen on Nicotiana tabacum : insights into fungal-plant interactions

Plant Signaling & Behavior, Journal Year: 2025, Volume and Issue: 20(1)

Published: Jan. 16, 2025

Tobacco (Nicotiana tabacum) black shank disease, caused by Phytophthora nicotianae, is a significant threat to tobacco crops, leading severe economic losses. Prolonged use of agrochemicals control this disease has prompted the exploration eco-friendly biological strategies. This study investigated effects Trichoderma harzianum, biocontrol agent, on N. tabacum in comparison P. focusing growth, biomass, root morphology and anatomy, hormonal changes, osmotic regulation. T. harzianum significantly enhanced plant biomass accumulation, system development, physiological attributes such as photosynthetic pigment levels antioxidant enzyme activity. In contrast, nicotianae negatively impacted these parameters, inhibiting growth function. Notably, increased proline content induced resistance mechanisms, mitigating stress promoting overall health. These findings highlight potential sustainable solution for managing while improving crop productivity.

Impact of Pristine and Aged Tire Wear Particles on Ipomoea aquatica and Rhizospheric Microbial Communities: Insights from a Long-Term Exposure Study

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 19, 2024

Tire wear particles (TWPs), generated from tire abrasion, contribute significantly to environmental contamination. The toxicity of TWPs organisms has raised significant concerns, yet their effects on terrestrial plants remain unclear. Here, we investigated the long-term impact pristine and naturally aged water spinach (Ipomoea aquatica) its rhizospheric soil. results indicated that natural aging reduced TWPs, as evidenced by decreased levels polycyclic aromatic hydrocarbons (PAHs) in soil themselves. Consequently, were found enhance plant growth chlorophyll content, whereas increased stress. Furthermore, improved organic matter (SOM) total carbon (TOC), thereby boosting microbial enzymes involved nitrogen cycling. Metabolomic analysis revealed upregulated key pathways related metabolism, enhancing stress responses. Additionally, rhizosphere bacterial diversity was higher under favoring nutrient-cycling taxa such Acidobacteriota Nitrospirota. Pristine may lead overproliferation certain dominant species, reducing soil, which could ultimately compromise health. These findings a deeper understanding mechanisms underlying TWP highlight necessity for further research across various species over different exposure durations comprehensive risk assessment.
