FIASCO; Genetic markers; Lateolabrax japonicus; Microsatellites

Lateolabrax japonicus, an economically important species, is widely consumed in the offshore coasts of China, Korea, and Japan. We identified 10 new L. japonicus microsatellite markers, using a modified protocol of fast isolation by AFLP of sequences containing repeats. Thirty L. japonicus individuals were collected from Xiamen, China, to ... more

Epinephelus coioides; IGF1Ra; IGF1Rb; Nucleotide diversity; Polymorphism

Orange-spotted grouper (Epinephelus coioides) is one of the most important marine fish and has a high market value. The insulin-like growth factor type 1 receptor (IGF1R) is a component of the insulin-like growth factor signaling system, and demonstrates important roles during growth. Based on information from livestock, we ... more

Collichthys lucidus; Gene clone; Matrix Gla protein; mRNA expression

The matrix Gla (gamma-carboxyglutamic acid-rich) protein (MGP), a vitamin K-dependent and Gla-containing protein, is a calcification inhibitor that mainly functions in tissue calcification and mineralization. In this study, we obtained the complete cDNA sequence of MGP from the spinyhead croaker (Collichthys lucidus), which we named Cl-MGP ... more

Biological control; Molecular marker; Population genetics; Rearing laboratories; SSR

Cotesia flavipes (Cameron) is a parasitoid wasp used in the biological control of the sugarcane borer (Diatraea saccharalis) (Fabr., 1794). Studies on the genetic diversity of C. flavipes are hampered by the lack of highly polymorphic molecular markers. In this report, a set of 11 microsatellite loci were ... more

Loci transferability; Microsatellite loci; Next-generation sequencing; Sillago japonica; Sillago sihama

Sillago sihama (Forsskål, 1775), a commercially important marine fishery species in the Indo-West Pacific, is being developed as a target species for aquaculture and stock enhancement in China. However, due to the limitations of traditional isolation methods, the available microsatellite loci, or simple sequence repeats (SSRs), of S. sihama lack ... more

Genetic variability; Hypostominae; Isoenzymes; Neotropical fishes

The genetic variability in three populations of Hypostomus hermanni from the tributaries of the rivers Ivaí (Keller), Tietê (Piracicaba), and Sapucaí (Sapucaí-Mirim) was determined using electrophoresis on starch gel. The variability in the genes for eight enzymes, namely, aspartate aminotransferase (EC, glucose-6-phosphate isomerase (EC ... more

Astyanax altiparanae; Astyanax asuncionensis; Mitochondrial DNA; Species discrimination

The morphological discrimination between the species Astyanax altiparanae and A. asuncionensis of the upper Paraná River and Paraguay River basins, respectively, has always been difficult. Two D-loop haplogroups of A. altiparanae are known, one with the presence (AltoPR) or the absence (AltoPR-D) of a 32-bp block similar to that in A. asuncionensis. We ... more

Censored data; GBLUP; Mixed model; Survival models

Age at the time of slaughter is a commonly used trait in animal breeding programs. Since studying this trait involves incomplete observations (censoring), analysis can be performed using survival models or modified linear models, for example, by sampling censored data from truncated normal distributions. For genomic selection, the greatest genetic gains can be ... more

Calf testis; Germline stem cells; Glial cell line-derived neurotrophic factor; Leukemia-inhibitory factor; Proliferation; Sperm differentiation

Germline stem cells are the only such capable of transmitting genetic information in vivo. The isolation and culture of these cells in vitro provide a unique model to understand sperm differentiation and hence, spermatogenesis and male fertility. In this study, we isolated, purified, and cultured germline stem cells from the testes of newborn ... more

Dry matter intake; Feed intake; Performance traits; Residual feed intake; Variance partitioning

Feed intake, feed efficiency, and weight gain are important economic traits of beef cattle in feedlots. In the present study, we investigated the physiological processes underlying such traits from the point of view of systems genetics. Firstly, using data from 1334 Nellore (Bos indicus) cattle and 943,577 single nucleotide polymorphisms (SNPs), a genome- ... more
