Comparative transcriptomics of nematode embryonic development. (A) For 3658 C. elegans genes, the temporal gene expression profiles cluster by K-means (on correlation coefficients) into six general patterns. (B) Expression profiles of C. briggsae orthologs of the C. elegans genes shown in A. (C) C. briggsae orthologs are reordered within the C. elegans defined clusters. To the right, a few specific genes are indicated. The K-means cluster of each C. elegans and C. briggsae gene is provided in Supplemental Table S3.
