Valuation of Ecosystem Services for the Sustainable Development of Hani Terraces: A Rice-Fish-Duck Integrated Farming Model.

As a complementary and symbiotic agro-ecological cycle system, a nature-based integrated rice-fish-duck farming ecosystem was developed in the Honghe Hani Rice Terraces. The main research objective was to evaluate the ecosystem services based on case studies of the Hani integrated rice-fish-duck terraced farming system and determine its potential and its importance as an ecological asset. We developed a valuation model to assess the value of the integrated farming system based on the three aspects of provisioning, regulation and maintenance, and cultural services; we selected eight groups and 10 indictors to evaluate the ecosystem services of the integrated ecosystem in Honghe Hani Rice Terraces was 3.

Developmental Expression of HSP60 and HSP10 in the Coilia nasus Testis during Upstream Spawning Migration.

Heat shock protein 60 (HSP60) and heat shock protein 10 (HSP10) are important chaperones, which have been proven to have essential roles in mediating the correct folding of nuclear encoded proteins imported to mitochondria. Mitochondria are known as the power house of the cell, with which it produces energy and respires aerobically. In this regard, the obtained HSP60 and HSP10 have typical characteristics of the HSP60/10 family signature.

Whole genome sequencing of Chinese clearhead icefish, Protosalanx hyalocranius.

Chinese clearhead icefish, Protosalanx hyalocranius , is a representative icefish species with economic importance and special appearance. Due to its great economic value in China, the fish was introduced into Lake Dianchi and several other lakes from the Lake Taihu half a century ago. Similar to the Sinocyclocheilus cavefish, the clearhead icefish has certain cavefish-like traits, such as transparent body and nearly scaleless skin.

Changes of gonadotropin-releasing hormone receptor 2 during the anadromous spawning migration in Coilia nasus.

Background: An increase in the activity of the pituitary-gonad axis (PG-axis) and gonad development are essential for the onset of spawning migration in teleosts. In the fish Coilia nasus, gonad development and spawning migration up the Yangtze River occurs by the end of each summer. We hypothesized that gonadotropin releasing hormones receptor 2 (GnRH-R2), which together produce a signal that interacts with the PG-axis, may help to regulate spawning migration processes.

Molecular Characteristic, Protein Distribution and Potential Regulation of HSP90AA1 in the Anadromous Fish Coilia nasus.

Heat shock proteins play essential roles in basic cellular events. Spawning migration is a complex process, with significant structural and biochemical changes taking place in the adult gonad. To date, the molecular mechanisms underlying migration reproductive biology remain undetermined.

Testes transcriptome profiles of the anadromous fish Coilia nasus during the onset of spermatogenesis.

RNA-Seq technology has been widely applied to transcriptomics, genomics and functional gene study. Here, we performed de novo transcriptome sequencing to produce 23,842,172 clean reads representing a total of 4,815,798,404 (4.8 Gb) nucleotides from comprehensive transcript dataset for testis of Coilia nasus.

Complete mitochondrial genome of Lateolabrax maculatus.

In this study, we sequence the complete mitochondrial genome of Lateolabrax maculatus. This mitochondrial genome is 16,597 bp in length, encoding 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a non-coding control region as found in other vertebrates, with the gene synteny identical to those of typical vertebrates. Control region (D-Loop), of 929 bp in length, is located between tRNA(Pro) and tRNA(Phe).

Ovary transcriptome profiling of Coilia nasus during spawning migration stages by Illumina sequencing.

Coilia nasus is an anadromous kind of small to moderate size fish species, and limited transcriptomics research has been performed. In the present study, we performed Illumina sequencing to produce a 22,996,612 clean reads representing with a total of 4,599,079,601 (4.5Gb) nucleotides comprehensive transcript dataset for ovary of C.

Characteristic of PGDS potential regulation role on spermatogenesis in the Chinese mitten crab Eriocheir sinensis.

Prostaglandin D synthase (PGDS) catalyzes the isomerization of PGH2 to produce PGD2 in the presence of sulfhydryl compounds. In this study, a full length PGDS gene comprising 1250 nucleotides from the Chinese mitten crab Eriocheir sinensis (Es-PGDS) was characterized, with a 615 bp open reading frame encoding 204 amino acid residues. Its deduced peptide has high homology with other species' PGDS protein.

Molecular cloning and expression analysis of chymotrypsin-like serine protease from the redclaw crayfish (Cherax quadricarinatus): a possible role in the junior and adult innate immune systems.

A novel chymotrypsin-like serine protease (CLSP) was isolated from the hepatopancreas of the redclaw crayfish Cherax quadricarinatus (Cq-chy). The full-length cDNA of Cq-chy contains 951 nucleotides encodes a peptide of 270 amino acids. The mature peptide comprising 223 amino acids contains the conserved catalytic triad (H, D, and S).
