Changes in Arabidopsis thaliana gene expression in response to silver nanoparticles and silver ions

ABSTRACT: The release of silver nanoparticles (SNPs) in the environment has raised concerns about their effects on living organisms, including plants. In this study, changes in gene expression in Arabidopsis thaliana exposed to SNPs and silver ions (Ag+) were analyzed using Affymetrix expression microarrays. Exposure to 5 mg SNPs L-1 (20 nm) for 10 days resulted in up-regulation of 286 genes and down-regulation of 81 genes by reference to non-exposed plants. Exposure to 5 mg Ag+ L-1 for 10 days resulted in up-regulation of 84 genes and down-regulation of 53 genes by reference to non-exposed plants. Many genes differentially expressed by SNPs and Ag+ were found to be involved in plant response to various stresses: up-regulated genes were primarily associated with response to metals and oxidative stre
