We have assembled data from Caenorhabditis elegans DNA
microarray experiments involving many growth conditions, developmentalstages, and varieties of mutants. Co-regulated genes were groupedtogether and visualized in a three-dimensional expression mapthat
displays correlations of gene expression profiles as distancesin two
dimensions and gene density in the third dimension. Thegene expression
map can be used as a gene discovery tool to identifygenes that are
co-regulated with known sets of genes (such asheat shock, growth
control genes, germ line genes, and so forth)or to uncover previously
unknown genetic functions (such as genomicinstability in males and
sperm caused by specific transposons).
