scallop genome reveals molecular adaptations to semi sessile life and neurotoxins
Nature Communications, 2017Co-Authors: Yuli Li, Wenqian Jiao, Yan Miao, Xiaoli Hu, Jinbo Zhang, Xiaokang Zhang, Lingling Zhang, Ji Li, Jing Wang, Taoran ChengAbstract:Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior are well recognized, but the underlying molecular mechanisms are largely unknown. Here, we investigate the genome, various transcriptomes, and proteomes of the scallop Chlamys farreri, a semi-sessile bivalve with well-developed adductor muscle, sophisticated eyes, and remarkable neurotoxin resistance. The scallop’s large striated muscle is energy-dynamic but not fully differentiated from smooth muscle. Its eyes are supported by highly diverse, intronless opsins expanded by retroposition for broadened spectral sensitivity. Rapid byssal secretion is enabled by a specialized foot and multiple proteins including expanded tyrosinases. The scallop uses hepatopancreas to accumulate neurotoxins and kidney to transform to high-toxicity forms through expanded sulfotransferases, probably as deterrence against predation, while it achieves neurotoxin resistance through point mutations in sodium channels. These findings suggest that expansion and mutation of those genes may have profound effects on scallop’s phenotype and adaptation. Bivalve molluscs have evolved various characteristics to adapt to benthic filter-feeding. Here, Li et al investigate the genome, transcriptomes and proteomes of scallop Chlamys farreri, revealing evidences of molecular adaptations to semi-sessile life and neurotoxins.

genomic in situ hybridization identifies parental chromosomes in hybrid scallop bivalvia pectinoida pectinidae between female Chlamys farreri and male argopecten irradians irradians
Comparative Cytogenetics, 2015Co-Authors: Xiaoting Huang, Lingling Zhang, Shi Wang, Zhenmin BaoAbstract:Interspecific crossing was artificially carried out between Chlamys farreri (Jones & Preston, 1904) ♀ and Argopecten irradians irradians (Lamarck, 1819) ♂, two of the dominant cultivated scallop species in China. Genomic in situ hybridization (GISH) was used to examine the chromosome constitution and variation in hybrids at early embryonic stage. The number of chromosomes in 66.38% of the metaphases was 2n = 35 and the karyotype was 2n = 3 m + 5 sm + 16 st + 11 t. After GISH, two parental genomes were clearly distinguished in hybrids, most of which comprised 19 chromosomes derived from their female parent (Chlamys farreri) and 16 chromosomes from their male parent (Argopecten irradians irradians). Some chromosome elimination and fragmentation was also observed in the hybrids.

Cloning and characterization of tryptophan 2,3‐dioxygenase gene of Zhikong scallop Chlamys farreri (Jones and Preston 1904)
Aquaculture Research, 2006Co-Authors: Zhenmin Bao, Lingling Zhang, Mingyu Shao, Aibin Zhan, Xiaoting HuangAbstract:A Zhikong scallop (Chlamys farreri Jones and Preston 1904) tryptophan 2,3-dioxygenase (TDO) gene fragment, down-regulated by Vibrio anguillarum challenge, was isolated using mRNA differential display in our previous work. In this paper, the full-length TDO gene was cloned by 5′-RACE. Chlamys farreri TDO gene consists of 1292 nucleotides encoding an expected polypeptide of 383 amino acids with an estimated molecular weight of 44.8 kDa and an isoelectric point of 6.35. The deduced amino acid sequence is 54–61% homologous to TDOs from Caenorhabditis elegans, Mus musculus, Danio rerio, Homo sapiens and Drosophila melanogaster, and shares several histidine residues important for the enzyme function in other species. Chlamys farreri TDO is expressed in the mantle, gill, digestive gland, testis, adductor muscle and kidney. Immunohistochemical analysis showed that C. farreri TDO was located mainly in the cytoplasm of most cell types. The non-specific distribution of C. farreri TDO suggests that it is involved in various cellular processes.
