Abstract
We have developed and opened a genome-wide database, termed SALAD database (http://salad.dna.affrc.go.jp/salad/), based on similarity clustering and distribution diagrams of evolutionarily conserved peptide motifs. Recent version (ver. 3) contains genome information on ten species, rice, sorghum, Arabidopsis thaliana, grape, lycophyte, moss, two green algae, red alga, and yeast. Using this database we can compare any annotations of your interest and discuss on their similarity relationships efficiently and quickly. In addition, this database has a new-type microarray data viewer (termed SALAD on ARRAYs), with which users can compare gene expression of microarray data for paralogous (or related) genes using Agilent platform. The gene expression level is shown as a gray-scale gradient in the colored boxes. We here report new functions on this viewer such as creating graph, selecting microarray datasets and changing the order of microarray data. Moreover, we plan to add public AtGenExpress microarray data (Affymetrix platform) which contains 783 array samples (29 series) from GEO. To display both Agilent and Affymetrix platform data we are now comparing these platform data.
