Homology comparison of ORFs contained in our cDNAs to known genes from different model organisms. The horizonal blocks represent numbers of the ORFs bearing homology to genes in a given species; different colors indicate the degree of homology. Each number listed atright indicates the total number of our ORFs having homologous genes in that organism. (B) Bacteria; (Y) yeast; (C) C. elegans; (D) Drosophila; (A) Arabidopsis; (M) mammals not including primates.
