Association; Chicken; Diplotype; GJA1; Growth traits; Polymorphisms

This study aimed to screen single nucleotide polymorphisms (SNPs) in the chicken gap junction protein alpha 1 (GJA1) gene, and to investigate their association with five growth traits measured in 269 chickens encompassing Chinese indigenous Beijing-You (BJY) and commercial Cobb broiler (CB) populations. Four variants were detected in the chicken GJA1 gene, in which one ... more

Akirin2 expression; Bursa; Chicken; Immune response; Liver

Akirin2 is a nuclear factor that plays an important role in the development and regulation of innate immune response. In this study, akirin2 gene expression in several primary immune organs (liver, thymus, and bursa) of Hi-Line Brown chicken administered with the LoSota vaccine was analyzed during the various stages of increase in Newcastle disease virus antibody titer. The ... more

Chicken; Piwi genes; SNP; Target-capture sequencing

The P-element-induced wimpy testis (Piwi) gene is involved in germline stem cell self-renewal, meiosis, RNA silencing, and transcriptional regulation. Piwi genes are relatively well conserved in many species, but their function in poultry species is unclear. In this study, Piwi genes were sequenced using a target-sequence capture assay in quail and 28 breeds of ... more

Chicken; Function annotation; miRNA-1757; Polymorphisms; Target gene

Single nucleotide polymorphism in microRNAs (miRNA) may influence their target gene selection and regulation efficiency, leading to animal phenotypic variation. The aim of this study was to evaluate the possible effect of single nucleotide polymorphisms in the miRNA-1757 gene precursor region (pre-mir-1757) on economic-related traits in chicken. Genotyping was performed using ... more

Age; Expression pattern; Myogenic factor; Sex

The aim of this study was to investigate the myogenic factor mRNA expression pattern of Pax7, Myf5, MyoG, and Myostatin mRNA at different ages, sexes, and muscle tissues of Datong yaks. The expression patterns in semimembranosus (SM), quadriceps femoris (QF), and triceps muscle of arm (TM) were detected by quantitative real-time polymerase chain ... more

Age; Anopheles funestus; P450 expression; Pyrethroid resistance

Anopheles funestus is a major vector of malaria in most of the African region. Resistance to pyrethroid and carbamate insecticides has been recorded in populations of this species in South Africa and Mozambique. The P450 gene, CYP6P9, has been shown to be highly transcribed in a permethrin (pyrethroid)-resistant laboratory strain, FUMOZ-R, originating from southern ... more

Age; Breed; Chicken; Cholesterol content; Egg yolks; Layer

The objective of this study was to investigate the deposition rule of yolk cholesterol in Lushi Green-shelled and Silky Fowl layers. A total of 90 layers of each breed were selected at an age of 15 to 51 weeks. Productive performance was recorded on a weekly basis, whereas yolk cholesterol was determined at 4-week intervals from 21 to 51 weeks of age. The average yolk cholesterol content ... more

Chicken; Mitochondrial genome; Phylogenetic relationship

In this study, we sequenced the complete mitochondrial DNA of Chinese indigenous Jinhu Black-bone and Rugao chickens. The two chicken mitochondrial genomes were deposited in GenBank under accession Nos. KP742951 and KR347464, respectively. The complete mitochondrial genomes of Jinhu Black-bone and Rugao chickens were sequenced and found to span 16,785 and 16,786 bp, respectively, and ... more

Chicken; Intramuscular fat; Lipoprotein lipase gene; meat quality

Lipoprotein lipase (LPL) is a key enzyme in lipid metabolism. This study investigated LPL gene expression, LPL enzyme activity, and the correlation of each with intramuscular fat (IMF) in Chinese Guangxi san-huang (GXSH) and Arbor Acres (AA) chickens. The results showed that age and breed had significant effects on LPL expression and enzyme activity. Correlation analyses ... more

To elucidate the resistance of high-yield hybrid rice (Oryza sativa L.) at the seedling stage to low temperature, photosynthetic characteristics, such as membrane lipid peroxidation, fatty acid composition, and chloroplast ultrastructure, were investigated in a newly developed super-hybrid rice ('Liangyoupeijiu') and a traditional chill-sensitive hybrid rice ('Shanyou63'), with 20°C as the ... more
