Acid rain, as a worldwide environmental issue, can cause serious

damage to plants. In this study, we provided the firstcase study on the

systematic responses of arabidopsis (Arabidopsis thaliana (L.) Heynh.) to

simulated acid rain (SiAR) by transcriptomeapproach. Transcriptomic analysis

revealed that the expression of a set of genes related to primary metabolisms,

includingnitrogen, sulfur, amino acid, photosynthesis, and reactive oxygen

species metabolism, were altered under SiAR. In addition,transport and signal

transduction related pathways, especially calcium-related signaling pathways,

were found to play importantroles in the response of arabidopsis to SiAR

stress. Further, we compared our data set with previously published data sets

onarabidopsis transcriptome subjected to various stresses, including wound,

salt, light, heavy metal, karrikin, temperature,osmosis, etc. The results

showed that many genes were overlapped in several stresses, suggesting that

plant response to SiAR isa complex process, which may require the participation

of multiple defense-signaling pathways. The results of this study willhelp us

gain further insights into the response mechanisms of plants to acid rain

stress.
