Naphthalene is of global environmental concern because it is assumed to contribute considerably to human cancer risk. Plants are important in removing naphthalene from the atmosphere and soil. However, there remains insufficient knowledge on plant response to this compound. To determine the mechanism of naphthalene uptake and transduction in plants, as well as plant response to this compound, a microarray system was used to analyze gene expression patterns in Arabidopsis thaliana after irrigation with 2.0mM naphthalene. A total of 247 differentially expressed genes were identified as upregulated by naphthalene. These genes might specifically contribute to naphthalene uptake, transformation, conjugation, and compartmentalization in the plant. The potential role of upregulated genes in plant defense to naphthalene and the use of phytosensing for naphthalene detection were also discussed.
萘具有全球性的环境关注，因为它被认为对人类癌症风险有很大的贡献。植物在从大气和土壤中去除萘方面起着重要作用。然而，对于植物对这种化合物的反应，仍然缺乏足够的知识。为了确定植物对萘的吸收和转导机制，以及植物对这种化合物的反应，使用微阵列系统分析了用 2.0mM 萘灌溉后拟南芥基因表达模式。总共鉴定出 247 个差异表达基因被萘上调。这些基因可能专门有助于植物对萘的吸收、转化、结合和区室化。还讨论了上调基因在植物对萘的防御中的潜在作用以及利用植物感应检测萘。
