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

Environment International, Год журнала: 2025, Номер 195, С. 109257 - 109257

Опубликована: Янв. 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.

Mechanistic Concept of Physiological, Biochemical, and Molecular Responses of the Potato Crop to Heat and Drought Stress

Plants, Год журнала: 2022, Номер 11(21), С. 2857 - 2857

Опубликована: Окт. 26, 2022

Most cultivated potatoes are tetraploid, and the tuber is main economic part that consumed due to its calorific nutritional values. Recent trends in climate change led frequent occurrence of heat drought stress major potato-growing regions worldwide. The optimum temperature for production 15–20 °C. High-temperature water-deficient conditions during growing season result several morphological, physiological, biochemical, molecular alterations. morphological changes under may affect process stolon formation, tuberization, bulking, ultimately affecting yield. This condition also affects physiological responses, including an imbalance allocation photoassimilates, respiration, water use efficiency, transpiration, carbon partitioning, source–sink relationship. biochemical responses involve maintaining ionic homeostasis, synthesizing shock proteins, achieving osmolyte balance, generating reactive oxygen species, various pathways. Different networks include both gene regulation transcription factors involved at level combination hot conditions. article attempts present integrative content physio-biochemical combined effects drought, prominent change. Taking into account all these aspects there immediate need comprehensive screening germplasm application appropriate approaches tactics produce potato cultivars perform well heat-affected areas.

Melatonin interaction with abscisic acid in the regulation of abiotic stress in Solanaceae family plants

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

Опубликована: Сен. 11, 2023

Solanaceous vegetable crops are cultivated and consumed worldwide. However, they often confront diverse abiotic stresses that significantly impair their growth, yield, overall quality. This review delves into melatonin abscisic acid (ABA) biosynthesis roles in stress responses. It closely examines the intricate interplay between ABA managing within plants, revealing both collaborative antagonistic effects elucidating underlying molecular mechanisms. Melatonin mutually influence each other’s synthesis, metabolism of other plant hormones, a key focus this study. The study highlights melatonin’s role aiding management through ABA-dependent pathways genes melatonin-ABA interaction. Specifically, downregulates synthesis upregulates catabolism genes, leading to reduced levels. also directly scavenges H 2 O , enhancing antioxidant enzyme activities, thereby underscoring mediating Moreover, plays an essential multiple physiological processes including stomatal behaviors, wax accumulation, delay leaf senescence, seed germination, seedlings among others. Recognizing these relationships Solanaceae holds great importance for improving agricultural practices crop In summary, offers comprehensive overview recent studies on interplay, serving as valuable resource researchers breeders dedicated fortifying resilience productivity challenging environments.

A field study was conducted to understand the effectiveness of foliar applications ZnO-NPs (0, 50, 100 mg L−1) and SiO2-NPs 25, 50 on potato plant growth, morphology, nutrient uptake, oxidative stress, antioxidative response under drought conditions (i.e., 100% crop evapotranspiration ETc, 75% 50% ETc). Results revealed that water deficiency significantly hampered growth biomass production stimulated stress in potatoes. However, exogenous application improved attributes such as number branches, height, fresh dry biomass, leaf area, area index compared with untreated plants.
