The main objective of this research was to identify single‐nucleotide polymorphisms (SNPs) from an Expressed Sequences Tags (EST) data set generated by 454 pyrosequencing in the soft clam Mesodesma donacium. A total of 180 159 ESTs were yielded from a M. donacium cDNA library. De novo assembly was performed using stringent calling parameters, producing 10 178 contigs and 41 765 singletons. Here, a total of 2594 SNPs were discovered related to 613 consensus sequences, achieving a frequency of 1 SNPs per 260 bp. SNP variants showed that A/G, A/T and C/T were the most abundant among the identified polymorphisms. We validated a total of 12 SNPs loci by HRMA for annotated genes such as heat shock protein‐70 and the translation elongation factor 1‐alpha. The Gene Ontology analysis regarding molecular function level revealed that sequences with SNPs were mainly classified to protein and nucleotide binding, as well hydrolase activity, ion binding and oxidoreductase activity. Further, biological processes like cellular and metabolic process, biogenesis, localization and biological regulation were highly annotated. The most expressed genes were related to the mitochondrial electron transport chain, senescence‐associated protein, ubiquitin and actin. Interestingly, some relevant genes related to immune response and biomineralization showed a high abundance, such as tumor necrosis factor (TNF)‐alpha‐receptor‐like protein, serine protease inhibitor, heat shock protein, aragonite‐binding protein and ferritin. This study contributes to relevant genes associated with functional polymorphisms and gives an overview for future genetic investigations. 相似文献

Japanese eels (Anguilla japonica) perform large‐scale oceanic migrations between their spawning ground and growth habitats in continental waters during life history. However, between these migrations, they spend most of time in growth habitats such as rivers. To investigate the diel and seasonal activities, homing behaviour and home range of yellow‐phase Japanese eels in the lower reach of the Tone River, we tracked them throughout a year using a fine‐scale positioning system (VPS) based on acoustic telemetry. The tracked eels were generally nocturnal, but not exclusively. They were mainly mobile from spring to autumn, with little or no activity observed during winter. A transport‐release experiment showed that most eels returned to their original capture area within 13 days after release. The eels had very small home ranges (mean ± SD = 0.085 ± 0.068 km2), core areas (0.014 ± 0.014 km2) and linear home ranges (744 ± 268 m). They also tended to be distributed on one particular side of the river (right or left bank) and in one particular shore type (revetment or vegetation), rarely moving from one to the other. This study provides evidence for nocturnal, dormancy, homing behaviours, limited habitat use and small home range size in Japanese eels. The eels clearly showed strong fidelity to a “familiar” site, which contrasts with the long distances travelled during upstream and downstream migration phases in the river, and during spawning migrations in the ocean. 相似文献

为分析感染水霉菌对巨须裂腹鱼脾脏转录组的影响，探索水霉菌感染巨须裂腹鱼的分子机制，实验随机选取生活在同一水域中的5尾健康和5尾感染水霉菌的巨须裂腹鱼，采用PDA琼脂培养基和分子生物学方法对巨须裂腹鱼水霉菌进行分离鉴定，并采用Illumina HiSeqTM 2000 高通量测序平台，对健康和感染水霉菌的巨须裂腹鱼脾脏组织进行转录组测序，并对测序数据进行拼接、注释和差异表达基因分析。结果显示，从巨须裂腹鱼皮肤上分离鉴定得到3株水霉菌；转录组数据显示，健康组和感染水霉病组分别获得46 619 504 条和43 912 876 条数据，与健康组相比，感染水霉菌组共有1 889 个基因发生差异表达，其中1 414 个基因上调，475 个基因下调，随机选取6个差异表达基因进行实时荧光定量PCR (RT-qPCR)验证，验证结果与转录组测序一致。对健康组和感染水霉菌组的差异表达基因进行GO功能富集发现，上调基因主要富集于241个功能中，下调基因主要富集于60个功能中，上述基因主要涉及分子功能类、细胞组分类和生物过程类等生理功能；KEGG通路富集分析发现，差异表达基因主要富集在免疫疾病、内分泌和代谢疾病、病毒感染性疾病、消化系统及排泄系统等。研究表明，感染水霉菌会影响巨须裂腹鱼脾脏组织多种基因的表达量，实验结果为进一步探索巨须裂腹鱼水霉菌的感染机制奠定了基础。 相似文献

In order to describe the genetic diversity and phylogenetic relationship of five populations of cuttlefish (Sepiella japonica) along with China's coasts, partial 16S rDNA (510 bp in length) was amplified from 110 individuals. The five populations of cuttlefish inhabit Yellow Sea, East China Sea and South China Sea. In total, six haplotypes were identified and formed only one clade. Among the six haplotypes, one was shared by all populations, three appeared only in a single population, two appeared in two or three populations. Pair‐wise FST were not proportional to the geographical distances. Haplotype diversity and nucleotide diversity were low, 0.3866 ± 0.067 and 0.00120 ± 0.00081 respectively. Among the five populations, Zhoushan population exhibited the highest genetic diversity which was suggested as the better select of germplasm resources for the reproduction and releasing of S. japonica. 相似文献

Antibiotic resistance and repetitive‐element PCR fingerprinting in Aeromonas veronii isolates 下载免费PDF全文
下载免费PDF全文 This study evaluated antibiotic resistance and the related genes in total 47 Aeromonas veronii isolates from pet fish, eel (Anguilla japonica) and koi (Cyprinus carpio) in Korea. In comparison with the antibiotic susceptibilities of isolates from eel and koi, those of pet fish were more resistant to ceftiofur, aminoglycosides, tetracycline and nitrofurantoin. And isolates from pet fish showed high prevalences of class 1 integron, quinolones and tetracycline resistance determinants than those from eel and koi. Repetitive‐element palindromic PCR (rep‐PCR) showed larger diversities among A. veronii isolates. Collectively, pet fish may be a reservoir for multiple clones of A. veronii involved in antibiotic resistance. In this aspect, imported fish in the aquaculture trade should be steadily and continually screened for bacterial antibiotic resistance and related genes. 相似文献

The study aims to evaluate the feasibility of completely replacing raw frozen shrimp Palaemon gravieri diets with raw frozen Antarctic krill (Euphausia superba) in the diets of cuttlefish Sepiella japonica. To address the knowledge gap, we conducted a 60‐day feeding trial. At the end of the experiment (day 60), the cuttlefish Sepiella japonica eating Palaemon gravieri (SJP) grew significantly faster than those eating Euphausia superba (SJE), with the specific growth rate (SGR)SJP (7.92%) > (SGR)SJE (7.09%). Approximately 33.3% and 20.0% mortality was observed in the SJE and SJP, during the course of the experiment respectively. Some important fatty acids (i.e. n‐3 and n‐6 PUFAs) were elevated in SJE with respect to SJP. Replacement of Antarctic krill increased the diversity of the gut microbiome composition in the SJE group. Fluoride accumulated in the ink sac and cuttlebone of cuttlefish in SJE. Overall, these findings imply that PUFA‐rich Antarctic krill could replace P. gravieri shrimp for feeding cuttlefish S. japonica. 相似文献
