Supplementary file 3, Expression level of the Arabidopsis transcripts in FPKM (Fragments Per Kilobase of transcript per Million mapped reads)

This study focuses on understanding how plants, specifically Arabidopsis thaliana, respond to two major pollutants, lead (Pb) and vanadium (V) found in oil contaminated land. While the effects of these pollutants on animals are well-studied, their impact on plants is not as clear. To fill this gap, we exposed Arabidopsis seedlings to Pb and V and analyzed the changes in gene expression using advanced sequencing and validated the data using RT PCR technique. The results showed that exposure to Pb and V led to significant changes in gene expression in Arabidopsis seedlings compared to untreated samples. Through Gene Ontology and pathway analysis, we identified several biological processes and pathways associated with the differentially expressed genes. Overall, this investigation sheds light on the molecular mechanisms underlying the toxicity and tolerance of Arabidopsis to Pb and V, providing valuable insights into how plants respond to heavy metal stress.本研究聚焦于解析植物——尤其是模式植物拟南芥（Arabidopsis thaliana）——对石油污染土壤中两种主要污染物铅（Pb）与钒（V）的响应模式。目前学界对这类污染物在动物体内的影响已有较为充分的研究，但它们对植物的作用效应尚未得到清晰阐明。为填补这一研究空白，我们将拟南芥幼苗暴露于铅与钒胁迫环境中，采用先进测序技术分析其基因表达变化，并通过逆转录PCR（RT PCR）技术对所得数据进行验证。 实验结果表明，与未处理对照组相比，铅与钒胁迫会导致拟南芥幼苗的基因表达发生显著改变。通过基因本体（Gene Ontology）富集分析与通路富集分析，我们筛选出多个与差异表达基因相关的生物学过程及调控通路。综上，本研究阐明了拟南芥对铅与钒的毒性响应及耐受机制的分子基础，为解析植物应对重金属胁迫的响应机制提供了极具价值的参考见解。
