Expression data from roots and first two leaves of tomato seedlings growing on regular MS medium or MS medium supplemented with multi-wall carbon nanotubes (0, 50, 100, 200 ug/ml) or activated carbon (50 mg/ml). Solanum lycopersicum

To investigate effects of carbon nanotubes (CNTs) om total expression profile of tomato plants we introduced CNTs in MS agar medium in concentrationd 0, 50, 100, 200 ug/ml Objectives for this study included the identification of genes that were up or down-regulated at the transcriptional level in tomato seedlings in response to carnom nanotubes (CNTs). Overall design: 10 day old root tips and first two leaves of wild type tomato seedlings (cv. Micro-Tom) growing on regular MS agar medium or MS medium supplemented with carbon nanotubes (50, 100, 200 ug/ml) or MS medium supplemented with activated carbon (50 ug/ml) were selected for RNA extraction and hybridization on Affymetrix microarrays.
