Two complementary DNA (cDNA) libraries were constructed from phyllosomas and hemocytes of adult Japanese spiny lobster Panulirus japonicus and a total of 2,673 expressed sequence tags (ESTs) were obtained. After assembly and clustering, 450 and 458 unique sequences
were found from the phyllosoma and hemocyte cDNA libraries, respectively. Of these, 114 and 220 ESTs showed significant homologies
with known genes in the National Centre for Biotechnology Information (NCBI) database. The remaining sequences were of unknown
function. Immune-related genes found in this study include lectin, proteinase inhibitor, prophenoloxidase, heat-shock protein,
antimicrobial peptide, and a few putative defense-related proteins. 相似文献

In order to elucidate mechanisms of tyramine accumulation during fish sauce production, two tyramine-producing bacterial strains, referred to as TyrA and TyrB, were isolated from fish sauce mash accumulating over 141 mg of tyramine per 100 g of sample. Both strains were identified as Tetragenococcus halophilus based on phenotypic characterization and a 16S rRNA gene sequence analysis. Molecular analysis of the tyramine-producing gene in the two strains confirmed the presence of a ~30-kb plasmid encoding a single copy of the pyridoxal phosphate-dependent tyrosine decarboxylase gene (tdcA) along with three other genes related to tyramine synthesis (tdc cluster). The complete nucleotide sequences of plasmids extracted from the two strains indicated that both plasmids were almost identical, except for a 1.6-kb transposon sequence in the plasmid from the strain TyrB. Both plasmids had a replication region, a plasmid maintenance region, and two putative mobile genetic elements located upstream and downstream of the tdc cluster. This structure was identical to that of tetragenococcal plasmids encoding histidine decarboxylase (hdcA), which were sequenced previously. These results suggest a common origin for plasmids encoding hdcA and tdcA. In addition, the genes for both these biogenic amines are distributed among tetragenococcal species via this plasmid. 相似文献

Pacific bluefin tuna (Thunnus orientalis) has high market value, but its wild populations have decreased in recent years. The broodstock of Pacific bluefin tuna that were hatched artificially and reared under aquaculture conditions is beginning to be used for production. The creation of broodstock with commercially valuable traits, such as rapid growth, is therefore of great interest. Genetic linkage map‐based identification of markers associated with quantitative trait loci (QTLs) facilitates marker‐assisted selection (MAS) breeding and allows efficient genetic improvement of broodstock. Single nucleotide polymorphism (SNP)‐based genetic linkage map construction using the genotyping‐by‐sequencing method can expand the number of mapped markers and help identify growth‐related QTLs. In this study, we constructed sex‐specific maps for 24 linkage groups consisting of 677 SNP and 651 microsatellite markers. The total lengths of 93 progenies in the mapping population followed normal distribution, with an average length of 9.4 mm. We performed composite interval mapping in the mapping population. QTL analysis revealed one significant QTL in LG10 on the female linkage map. The genetic linkage map—the second such map generated for Pacific bluefin tuna—and the growth‐related QTLs detected in this study will be useful for tuna aquaculture MAS programs. 相似文献
