Polystyrene microplastic interaction with Oryza sativa: toxicity and metabolic mechanism
AI summary Read the abstract
Researchers confirmed for the first time that polystyrene nanoplastics can enter rice plant root cells through a process called endocytosis. This finding provides important new understanding of how microplastic contamination in soil may affect crop plants and potentially enter the food supply.
For the first time, we confirmed that PS nanoplastics can enter plant root cells through endocytosis, which will provide important new insights into microplastic-induced phytotoxicity.

Uptake and translocation of nano/microplastics by rice seedlings: Evidence from a hydroponic experiment
AI summary Read the abstract
In a hydroponic experiment, researchers showed that both nano-sized (80 nm) and micro-sized (1 micrometer) polystyrene particles were absorbed by rice plant roots and transported up into stems and leaves. The particles traveled through the plant's vascular system and accumulated in cell walls and between cells. This finding is concerning because it demonstrates that microplastics in soil and water can enter food crops like rice and potentially reach people through their diet.
Response of rice (Oryza sativa L.) roots to nanoplastic treatment at seedling stage
AI summary Read the abstract
Researchers exposed rice seedlings to polystyrene nanoplastics and found that the particles were taken up by the roots, aided by water-transporting proteins in the plant. The nanoplastics triggered oxidative stress, reduced root length, and disrupted carbon metabolism and hormone production in the seedlings. The study raises concerns that nanoplastic contamination in agricultural soils could affect crop growth and potentially enter the human food supply through rice consumption.
Polystyrene nanoplastics affect seed germination, cell biology and physiology of rice seedlings in-short term treatments: Evidence of their internalization and translocation
AI summary Read the abstract
Researchers found that polystyrene nanoplastics were absorbed by rice roots and translocated to shoots, impairing seed germination, seedling growth, and cell division while disrupting reactive oxygen species homeostasis in short-term treatments.
Uptake and transport of micro/nanoplastics in terrestrial plants: Detection, mechanisms, and influencing factors
AI summary Read the abstract
This review summarizes how micro and nanoplastics enter and move through plants, including uptake through roots and leaves via processes like endocytosis and movement through cell walls. Smaller particles penetrate more easily, and factors like surface charge and soil conditions affect how much plastic plants absorb. The findings are important because they show that crops can take up microplastics from contaminated soil, creating a potential pathway for these particles to reach the human diet.
Molecular mechanisms of toxicity and detoxification in rice (Oryza sativa L.) exposed to polystyrene nanoplastics
AI summary Read the abstract
Researchers studied how polystyrene nanoplastics affect rice seedlings at the molecular level. They found that nanoplastic exposure significantly reduced root and shoot growth by over 50%, while triggering oxidative stress and activating genes related to both toxicity and defense responses. The study provides new insights into how crop plants respond to nanoplastic contamination at the genetic and physiological level.
