The differential gene expression analysis between embryos and pseudogerms of M. cingulum. a Heatmap of differentially expressed genes in embryos and pseudogerms. The signal transduction pathways were enriched in the embryos (b) whereas the pathways of carbohydrate metabolism were enriched in the pseudogerms (d). The enriched pathways were consistent with the fate and function of embryos (cell cycle, FOXO, Wnt, Hedgehog, etc.) (c) and pseudogerms (hormone biosynthesis, inositol phosphate metabolism, amino sugar and nucleotide sugar metabolism, etc.) (e)
