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.

Salt-tolerant plants (STPs) play an important role in saline-alkali soil remediation, but their interaction with microorganisms remain incompletely elucidated. This study explored the effects on microbial community structure, function, and quality land of four treatments: no plant (CK), Triticum aestivum L. (TA), Tamarix chinensis Lour. (TC), Hibiscus moscheutos Linn. (HM). The results indicated that planting TC, TA, HM effectively reduced electrical conductivity (EC) by 82.9, 88.3, 86.2%, respectively. TC TA significantly decreased pH from 8.79 to 8.35 8.06, respectively, (p < 0.05). Moreover, nutrient content enzymatic activities were enhanced. Notably, exhibited most significant improvement.
