“…Microplastics degrade the quality of many plants, like rape, cucumbers, rice, etc. In rice (Y900), polystyrene microplastics inhibited metabolites and caused quality deterioration [57]. It was found that microplastics facilitated heavy metal entry in brome rape and along with heavy metal microplastics caused loss of quality of the rape by altering malondialdehyde, sugar and vitamin C content [58].…”

Microplastics are currently a major global threat as they enter the ecosystem in large quantities daily and are able to persist in the environment for a long period of time. Current research focuses mainly on aquatic and related ecosystems; however, little information is available on the sources, possible accumulation, and pathways of microplastics in agroecosystems. It was previously thought that plastic particles could not be taken up or accumulate in plant bodies, but with modern technology, it has been observed that plastic particles are able to penetrate plants at the micro and nanoscales through transpiration pull forces, and in some cases through the leaves with foliar application. The purpose of the study was to identify potential sources of microplastics, their ways of entry into agroecosystems as well as into plants, and the effects of microplastics on the physiological processes of plants. We highlighted the harmful effects of these pollutants on agricultural ecosystems. Microplastics causes pore space blockages on root surfaces and oxidative damage. Moreover, they inhibit nutrient and water uptake, decrease germination capability, and have negative effects on product quality.

“…The production, regulation, and emission of floral VOCs are important for pollinator attraction and guidance . Terpenoids are the largest floral volatile class, while phenylpropanoids derived from the amino acid phenylalanine are the second largest class of plant VOCs. − The MNPs stress in several plants caused the disruption of terpenoids biosynthesis and metabolism, terpene synthase activity, and triterpenoid biosynthesis pathways. , The disruption in these pathways could have greater impact on the production and emission of floral volatiles.

Microplastics and nanoplastics (MNPs) contamination is an emerging environmental and public health concern, and these particles have been reported both in aquatic and terrestrial ecosystems. Recent studies have expanded our understanding of the adverse effects of MNPs pollution on human, terrestrial, and aquatic animals, insects, and plants. In this perspective, we describe the adverse effects of MNPs particles on pollinator and plant health and discuss the mechanisms by which MNPs disrupt the pollination process. We discuss the evidence and integrate transcriptome studies to investigate the negative effects of MNPs on the molecular biology of pollination, which may cause delay or inhibit the pollination services. We conclude by addressing challenges to plant−pollinator health from MNPs pollution and argue that such harmful effects disrupt the communication between plant and pollinator for a successful pollination process.

“…Rice is an essential food crop with a large planting area, previous studies have revealed the adverse effects of MPs on rice germination, growth, and yield through metabolomics and transcriptomics (Zhang et al, 2021;Chen et al, 2022;Wu et al, 2022). Hence, investigating and studying the distribution characteristics of MPs in paddy soils is crucial for food security, plant and animal growth, and human health (Wang et al, 2021).…”

Microplastics (MPs), as new pollutants in agroecosystems, have already attracted widespread attention from scientists. However, our understanding of MP geographic distribution and its influencing factors across spatial scales remains poor. Here, a regional-scale field investigation was conducted to assess the distribution characteristic of MPs in five major rice-growing regions of China, and we explored the roles of biological and abiotic factors, especially stoichiometry and microbial influences on MP distribution. MPs were observed in all sampling sites, averaging 6,390 ± 2,031 items⋅kg–1. Sizes less than 0.5 mm and black and transparent MPs dominated. Fiber, classified as one of the MP shapes, occurred most frequently. MP community analysis, firstly used in paddy soil, revealed more black MPs abundance in Henan (HE), more rayon, blue, and other colors MPs in Hunan (HN), more transparent MPs in Tianjing (TJ), and more PE MPs in Heilongjiang (DB). Higher MP community diversity was found in most south paddy soils of this study, due to a broader range of sources. C/N showed a positive relationship with pellet-shaped MP abundance and MPs of size between 2 and 5 mm (P < 0.05). Chao1 index of soil microbial communities was positively correlated with the MP abundance, MPs of size less than 0.5 mm, and fiber abundance. The minimum temperature was positively correlated with MP abundance (P < 0.05), implying the potential effects of the freeze-thaw process might exist. The regression analysis highlighted the important role of population quantity in determining MP abundance (R = 0.421, P = 0.02). This study confirmed the wide distribution of MPs in different soil depths of paddy lands in China and demonstrated that its distribution was influenced by population quantity and environmental variables, such as microbiology. These findings could provide a basis for the toxicological behavior of MPs and the potential risk to human health.
