Abstract
Transcriptional responses of hsp70 gene of the Folsomia candida were detected by relative real-time PCR assay when the springtail was exposed to a vegetable soil with different Hg concentrations or different exposure time. Results showed that the hsp70 gene expression level was significantly up-regulated when soil Hg was ≥0.25 mg·kg−1. The responses of this gene expression were strongly induced after 48 hours exposure under 1 mg·kg−1 of soil Hg, which was probably due to the fast and sensitive response of the gene transcription to the Hg stress. Thus, the results suggested that the gene could be used as a biomarker to monitor the Hg pollution in soil and help early and fast environmental diagnostics or ecological risk assessment of Hg contaminated soils.
