BACKGROUND Blunt snout bream (Megalobrama amblycephala) is an herbivorous freshwater fish species native to China and has been recognized as a main aquaculture species in the Chinese freshwater polyculture system with high economic value. Right now, only limited EST resources were available for M. amblycephala. Recent advances in large-scale RNA sequencing(More)
Vertebrate gut microbiome often underpins the metabolic capability and provides many beneficial effects on their hosts. However, little was known about how host trophic level influences fish gut microbiota and metabolic activity. In this study, more than 985,000 quality-filtered sequences from 24 16S rRNA libraries were obtained and the results revealed(More)
UNLABELLED The 5' cap structures of eukaryotic mRNAs are important for RNA stability and protein translation. Many viruses that replicate in the cytoplasm of eukaryotes have evolved 2'-O-methyltransferases (2'-O-MTase) to autonomously modify their mRNAs and carry a cap-1 structure (m7GpppNm) at the 5' end, thereby facilitating viral replication and escaping(More)
In this study, 23 genomic microsatellite DNA markers and 17 express sequence tag (EST)-derived microsatellites were developed and characterized using the fast isolation by AFLP of sequences containing repeats (FIASCO) method and data mining from public EST databases of mandarin fish (Siniperca chuatsi). These polymorphic microsatellite markers were then(More)
Most eukaryotic viruses that replicate in the cytoplasm, including coronaviruses, have evolved strategies to cap their RNAs. In our previous work, the nonstructural protein (nsp) 14 of severe acute respiratory syndrome coronavirus (SARS-CoV) was identified as a cap (guanine-N7)-methyltransferase (N7-MTase). In this study, we found that GTP, dGTP as well as(More)
In order to test the hypothesis that the expression levels of GH/IGF axis genes would be negatively related to the expression of the myostatin genes in fish species, we cloned six growth regulating genes including growth hormone receptors-1/-2 (GHRs), insulin-like growth factors-I/-II (IGFs) and myostatins-a/-b (MSTNs) from blunt snout bream (Megalobrama(More)
Blunt snout bream (Megalobrama amblycephala) is an economically important fish species in the Chinese freshwater polyculture system for its delicacy and high economic value. MicroRNAs (miRNAs) play important roles in regulation of almost all biological processes in eukaryotes. Although previous studies have identified thousands of miRNAs from many species,(More)
Tidal estuarine wetlands of China are rich in plant diversity, but several global change drivers, such as species invasion, are currently affecting the biogeochemical cycles of these ecosystems. We seasonally analyzed the carbon (C), nitrogen (N), and phosphorus (P) concentrations in litters and soils and in leaves, stems, and roots of the C3 invasive(More)
The complete mitochondrial genome of a New Zealand specimen of the deep-sea sponge Poecillastra laminaris (Sollas, 1886) (Astrophorida, Vulcanellidae), from the Colville Ridge, New Zealand, was sequenced using the 454 Life Science pyrosequencing system. To identify homologous mitochondrial sequences, the 454 reads were mapped to the complete mitochondrial(More)
Hyperplasia and hypertrophy are two distinct processes of skeletal muscle growth regulated by four myogenic regulatory factors (MRFs, contains MyoD, Myf5, Mrf4 and myogenin (MyoG)) and myostatin (MSTN). In this study, characterization of muscle morphology and satellite cells in juvenile (1-year-old) and adult (2-year-old) Megalobrama amblycephala was(More)
