As“Bohai Red”scallops were originated from the hybrids between the Peruvian scallop(Argopecten purpuratus)and the bay scallop(Argopecten irradians)northern subspecies(Argopecten irradians irradians).Twelve wnt members were identified from the two subspecies of bay scallop,and 13 wnt genes were found in the genome of the Peruvian *** structure analyses showed that most wnt genes poses all 5 conserved motifs except wnt1,wnt2,wnt6,and wnt9 in the bay scallops and wnt2 and wnt9 in the Peruvian ***,wnt8 gene was present while wnt3 was absent in both the bay scallops and the Peruvian *** analysis revealed that wnt3 might have disappeared in the early evolution of *** expression profile of wnt genes in the“Bohai Red”exposed to different temperatures was examined by *** show that expression of wnt genes responded differentially to temperature *** wnt genes such as wnt1,wnt6,wnt7,wnt11,and wntA that responded slowly to low and high temperature stresses may be related to the maintenance of basic *** wnt genes such as wnt4,wnt9,wnt5,and wnt2 that responded rapidly to low temperature may play an important role in organismal protection against low temperature *** yet some wnt genes including wnt10,wnt16,and wnt8 that responded quickly to high temperature stress may play key roles in response to high temperature *** results provide new insights into the evolution and function of wnt genes in bivalves and eventually benefit culture of“Bohai Red”scallops.

Objective To investigate the differential expression of wnt gene family wnt1、wnt2、wnt4、wnt5 and wnt11A/B in protoscoleces and adult of ***. Methods The SYBR Green Ⅰreal-time quantitative PCR and whole-mount in situ hybridization methods were applied to analyze the differential transcription and positioning of these genes in protoscoleces and adult of ***. Results The quantitative results showed that the wnt gene family were transcribed in both protoscoleces and adult of ***. The transcription of wnt1 and wnt2 were higher in adult of *** than protoscoleces, On the contrary, the transcription of wnt4、wnt5 and wnt11A/B were higher in protoscoleces than adult of ***. The whole-mount in situ hybridization results showed that the wnt gene family mRNA were mainly distributed in rostellum、suckers、hooks and margins of protoscoleces. Conclusion Based on these findings, the transcription and distribution of wnt1、wnt2、wnt4、wnt5 and wnt11 B in differential stages of *** has certain regularity, which laid down the foundation for further research of the roles of wnt gene family and wnt signal during the development of ***.
