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.

Microplastics pose a serious ecological threat to agricultural soils, as they are very persistent in nature. can enter the soil system different ways and present shapes concentrations. However, little is known about how plants react microplastics with concentrations shapes. To this end, we conducted factorial pot experiment wheat (Triticum aestivum L.) which mixed polystyrene (PS) (bead, fiber powder) at of 0, 1, 3 5%. Although all PS significantly reduced morphological growth traits, powder shape was microplastic that plant height (by 58–60%), fresh biomass 54–55%) dry 61–62%) most, especially 3% 5% compared 0% PS. Similar negative effects were also observed for root length weight concentrations, regardless shape. A concentration-dependent reduction leaf area index (LAI) observed. Interestingly, increasing concentration tended up-regulate activity antioxidant enzymes shapes, indicating potential complexity highly time-dependent response related various reactive oxygen species (ROS). Importantly, caused significant chlorophyll pigmentation photosynthetic rate. For transpiration rate, stomatal conductance intercellular CO2 concentration, on increased increase Overall, concluded higher potentially more devastating physiological biochemical attributes wheat, evidenced by pigments gas exchange parameters We recommend further research experiments not only translocation but tissue-specific retention sizes crops fully understand their impact food safety.

Phytochrome Alleviates Cadmium Toxicity by Regulating Gibberellic Acid and Brassinolide in Nicotiana Tabacum . L

Published: Jan. 1, 2024

Soil cadmium (Cd) pollution has emerged as a substantial environmental challenge globally, hampering crop production and endangering human health. Here, we found that photoreceptor phytochromes (PHYs) were involved in regulating Cd tolerance tobacco. Compared to wildtype (WT) plants, phytochrome-defective mutants (phyA, phyB, phyAB) displayed sensitive phenotype, had higher reactive oxygen species (ROS) accumulation malondialdehyde content. However, differences concentration among phyA mutants, phyB phyAB WT plants not observed. Consequently, the promoted biomass of thereby increasing accumulation. Furthermore, stress altered levels gibberellin (GA) brassinosteroid (BR), these phytohormones plants. GA3 application induced transcription genes encoding antioxidant enzyme suppressed expression associated with chlorophyll degradation, inhibiting breakdown decreasing ROS under conditions. Additionally, epibrassinolide spraying related synthesis, content maintaining plant acquisition ability. Our results suggested enhanced Nicotiana tabacum through BR GA, which contribute utilizing genetic engineering enhance phytoremediation efficiency.
