Integrated bioinformatics analysis of As, Au, Cd, Pb and Cu heavy metal responsive marker genes through <i>Arabidopsis thaliana</i> GEO datasets

Abstract

In general, the identified biomarker genes could help us understand the potential molecular mechanisms or signaling pathways responsive to heavy metal stress in plants, and could be applied as marker genes to track heavy metal pollution in soil and water through detecting their expression in plants growing in those environments.
