Microplastic stress in plants: effects on plant growth and their remediations

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Авг. 11, 2023

Microplastic (MP) pollution is becoming a global problem due to the resilience, long-term persistence, and robustness of MPs in different ecosystems. In terrestrial ecosystems, plants are exposed MP stress, thereby affecting overall plant growth development. This review article has critically analyzed effects stress plants. We found that stress-induced reduction physical accompanied by two complementary effects: (i) blockage pores seed coat or roots alter water nutrient uptake, (ii) induction drought increased soil cracking MPs. Nonetheless, physiological under four excessive production ROS, alteration leaf root ionome, (iii) impaired hormonal regulation, (iv) decline chlorophyll photosynthesis. Considering that, we suggested targeting redox regulatory mechanisms could be beneficial improving tolerance plants; however, antioxidant activities highly dependent on species, tissue, type, dose. also indirectly reduces altering productivity. However, MP-induced negative vary presence surface functional groups particle sizes. end, utilization agronomic approaches, including application regulators, biochar, replacing plastic mulch with crop residues, diversification, biological degradation, ameliorate The efficiency these methods MP-type-specific dose-dependent.

Biochar relieves the toxic effects of microplastics on the root-rhizosphere soil system by altering root expression profiles and microbial diversity and functions

Ecotoxicology and Environmental Safety, Год журнала: 2024, Номер 271, С. 115935 - 115935

The accumulation of microplastics in agricultural soil brings unexpected adverse effects on crop growth and quality, which is threatening the sustainability agriculture. Biochar an emerging amendment material interest as it can remediate pollutants. However, mechanisms underlying biochar alleviated toxic crops were largely unknown. Using a common economic crop, peanut targeted species, present study evaluated plant physiologica molecular response rhizosphere microbiome when facing microplastic contamination amendment. Transcriptome analyses conducted root treated with CK (no no addition), MP (1.5% polystyrene addition) MB microplastic+2% shell addition). results indicated that had inhibitory development bacterial diversity function. application could significantly promote expressions key genes associated antioxidant activities, lignin synthesis, nitrogen transport energy metabolism to alleviate reactive oxygen species stress, structure damage, nutrient limitation, inhibition induced by root. In addition, showed restore richness microbial communities inhibited availability regulating abundance cycling-related organic matter decomposition-related communities. Consequently, enhance promoting oxidative stress resistance, benefit microecological environment for development, thereby improved plant-soil system health microplastic-contaminated agroecosystem.

Effect of conventional and biodegradable microplastics on the soil-soybean system: A perspective on rhizosphere microbial community and soil element cycling

Environment International, Год журнала: 2024, Номер 190, С. 108781 - 108781

Опубликована: Май 28, 2024

As an exogenous carbon input, microplastics (MPs), especially biodegradable MPs, may significantly disrupt soil microbial communities and element cycling (CNPS cycling), but few studies have focused on this. Here, we assessing the effects of conventional low-density polyethylene (LDPE), polybutylene adipate terephthalate (PBAT), polylactic acid (PLA) MPs rhizosphere CNPS in a soil-soybean system. The results showed that PBAT-MPs PLA-MPs were more detrimental to soybean growth than LDPE-MPs, resulting reduction shoot nitrogen (14.05% 11.84%) biomass (33.80% 28.09%) at podding stage. In addition, dissolved organic (DOC) increased by 20.91% 66.59%, while nitrate (NO

Do Added Microplastics, Native Soil Properties, and Prevailing Climatic Conditions Have Consequences for Carbon and Nitrogen Contents in Soil? A Global Data Synthesis of Pot and Greenhouse Studies

Microplastics threaten soil ecosystems, strongly influencing carbon (C) and nitrogen (N) contents. Interactions between microplastic properties climatic edaphic factors are poorly understood. We conducted a meta-analysis to assess the interactive effects of (type, shape, size, content), native (texture, pH, dissolved organic (DOC)) (precipitation temperature) on C N contents in soil. found that low-density polyethylene reduced total (TN) content, whereas biodegradable polylactic acid led decrease (SOC). Microplastic fragments especially depleted TN, reducing aggregate stability, increasing N-mineralization leaching, consequently C/N ratio. size affected outcomes; those <200 μm both TN SOC Mineralization-induced nutrient losses were greatest at 1 2.5% weight. Sandy soils suffered highest contamination-induced depletion. Alkaline showed depletion, suggesting high degradability. In low-DOC soils, contamination caused 2-fold greater depletion than with DOC. Sites precipitation temperature had conclusion, there complex interactions determining impacts health. always risks but severity depends characteristics, properties, conditions, potential exacerbation by greenhouse emission-induced climate change.
