| 英文摘要 | Genes encoding Wnt ligands, which have important roles in cell communication and organ development, are restricted to multicellular animals. We systematically studied W nt genes from eumetazoan genomes, with emphasis on the poorly studied superphylum Lophotrochozoa(four annelids, seven mollusks, eight platyhelminths, one bdelloid rotifer, and one brachiopod species). Between 3 and 39 W nt loci were identified in each genome, and the protostome-specific loss of Wnt3 genes was confirmed. We identified gastropod-specific loss of Wnt8, refining the previously proposed mollusk-specific loss. Some duplicated Wnt genes belonging to a same subfamily or closely related subfamilies showed tandem distribution in the lophotrochozoan genomes, indicating tandem duplication events during Wnt family evolution. Members of the conserved Wnt10-Wnt6-Wnt1-Wnt9 cluster showed highly correlated expression patterns over time in two assayed lophotrochozoans, the oyster C rassostrea gigas and the brachiopod L ingula anatina, reflecting the possible similar function of the clustered W nt genes. |
