From stress to defense: Spatial confinement of nanoplastics in rice root cell walls via pectin matrix remodeling
Researchers showed that rice roots defend against nanoplastic intrusion by rapidly increasing pectin content in cell walls by 65%, which traps nearly half the nanoplastics within root tissue and stiffens cell walls to suppress upward transport to edible shoots.
Molecular mechanisms of toxicity and detoxification in rice (Oryza sativa L.) exposed to polystyrene nanoplastics
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.
Polystyrene nanoplastics induce cell type-dependent secondary wall reinforcement in rice (Oryza sativa) roots and reduce root hydraulic conductivity
Researchers found that polystyrene nanoplastics penetrating rice roots trigger a cell-type-specific defense response in which the plant reinforces its secondary cell walls with lignin and suberin in key barrier tissues, increasing wall thickness by up to 22% while simultaneously reducing the root's ability to absorb water by nearly 15%.
Effects of nanoplastics on the growth, transcription, and metabolism of rice (Oryza sativa L.) and synergistic effects in the presence of iron plaque and humic acid
This study examined how nanoplastics affect rice plant growth, finding that the tiny particles were absorbed by roots and entered plant cells. Nanoplastic exposure reduced important enzyme activity and protein levels in roots, disrupting normal plant metabolism. The presence of iron plaque and humic acid in the soil changed how much nanoplastic the plants took up, suggesting that real-world soil conditions play a key role in how crops are affected.

Mechanistic insight into the intensification of arsenic toxicity to rice (Oryza sativa L.) by nanoplastic: Phytohormone and glutathione metabolism modulation
Nanoplastics at environmentally realistic levels did not harm rice plants on their own, but when combined with arsenic they made arsenic toxicity significantly worse, reducing plant growth by up to 23%. The nanoplastics increased arsenic uptake by disrupting plant hormones and weakening the plant's natural detoxification systems. This is concerning because rice is a staple food for billions of people, and agricultural soils increasingly contain both nanoplastics and heavy metals.
