Microarray-based Analysis of Gene Expression in Lycopersicon esculentum Roots in Response to Cadmium, Chromium, Mercury and Lead
Ontology highlight
ABSTRACT: We hypothesize that microarray-based analysis of Lycopersicon esculentum is a sensitive tool for the early detection of potential toxicity of heavy metals, as well as an effective tool for identifying the heavy metal-specific genes. To test the hypothesis, the Agilent whole-genome cDNA microarrays were used to assess the effects of heavy metal on L. esculentum at relatively low concentrations (1/10 LC50 of heavy metals). Results showed that the characteristic gene expression profiles induced by Cd, Cr, Hg and Pb were not only distinct from the control but also distinct from one another, demonstrating the feasibility of discriminating between the effects of these four heavy metals present at relatively low concentrations. Moreover, heavy metal-specific genes were identified by microarray analysis. These findings support the above hypothesis.
