Transcriptomic and Metabolic Reprogramming of Durum Wheat under Nanoplastic Exposure

Polystyrene nanoplastics (PSNPs) are an emerging class of environmental contaminants whose effects on terrestrial plants remain poorly understood. Durum wheat (Triticum turgidum ssp. durum), one of the most important cereal crops worldwide, was used as a model to investigate how PSNP exposure influences plant physiology and gene regulation. In this study, wheat seedlings were exposed to controlled concentrations of PSNPs, and transcriptome-wide RNA sequencing was performed to evaluate changes in gene expression associated with stress response, growth regulation, and metabolic adaptation. The generated dataset provides comprehensive insights into the molecular mechanisms underlying plant responses to nanoplastic exposure. These data are expected to be valuable for the scientific community by contributing to the understanding of plant nanoplastic interactions, advancing environmental risk assessment of plastic pollution in agriculture, and supporting future studies on crop resilience to emerging contaminants

聚苯乙烯纳米塑料（Polystyrene nanoplastics, PSNPs）是一类新兴环境污染物，其对陆生植物的影响目前仍有待深入解析。硬粒小麦（*Triticum turgidum* ssp. *durum*）作为全球最重要的谷类作物之一，本研究以其为模式植物，探究PSNPs暴露对植物生理及基因调控的影响。本研究中，研究人员将小麦幼苗暴露于可控浓度的PSNPs环境中，并借助全转录组RNA测序技术，评估与胁迫响应、生长调控及代谢适应相关的基因表达变化。本数据集可为植物响应纳米塑料暴露的分子机制提供全面的认知视角。该数据集有望为科研领域提供重要参考：助力解析植物与纳米塑料的相互作用机制，推动农业塑料污染的环境风险评估工作，并为后续针对作物应对新兴污染物的抗逆性研究提供支撑。
