Pairwise comparison of gene expression in different biological conditions. Nuclear genes with >2-fold change in expression between the two conditions indicated (by either Tukey medians or SAM-calculated mean) were categorized into different functional categories or locations. Categories with very few representatives in either stage are not shown. Genes annotated as hypothetical or hypothetical conserved were further categorized as encoding proteins having a signal sequence (hyp+sig) or having at least one internal potential membrane domain (hyp +TMD).
