cDNA array experiment

This page allows searching for cDNA macroarray expression profiles. Searches can be done by accession number (e.g. BP058334), clone name (e.g. GENf001a09) or gene name (e.g. kinase). The retrieved data is raw signal intensity normalized by the total value of all spotted probes which was set to 1,000,000. Fold change values relative to uninfected root is indicated for N2, N4, N7 and N12 (2, 4, 7 and 12 days after Mesorhizobium loti inoculation) samples.

Select Clone/Accession/Gene

Search by the expression pattern is available by checking the box. The red and the blue pattens indicate the fold change of more than 2 and less than 0.5 relative to the signal value of uninfected root, respectively.
