Summary: Genetic analysis of porcine growth and fatness traits revealed correlations among different traits and identified significant loci on swine chromosome 4 and 7. As pigs age, the correlation between fatness and body weight increases, providing further insights into genetic mechanism of porcine growth and fat deposition.

Summary: The study investigated the genetic parameters of production and reproduction traits in Korean Duroc, Landrace, and Yorkshire pigs, revealing moderate to high heritability of production traits and low heritability of reproduction traits. Genetic correlations were found between certain traits, emphasizing the importance of careful breeding plans. The findings suggest potential for further improvement through selective breeding in Korean pig populations.

Summary: This research conducted a principal component analysis to identify the main traits related to peanut flavor. Genome-wide association studies revealed significant quantitative trait loci associated with total sugars and sucrose, and candidate genes for these traits were identified. The findings contribute valuable knowledge about the genetic control of peanut flavor.

Summary: In a genome wide association study on Duroc pigs, 28 potential single nucleotide polymorphisms associated with growth and fatness traits were identified. Genes such as VPS4B and PHLPP1 were highlighted as plausible candidates contributing to the genetic architecture of porcine growth and fatness traits. These findings enhance our understanding of the genetic mechanisms underlying swine growth and fatness traits, with potential application in pig breeding programs.

Summary: This study investigates the genetic architecture of feed efficiency (FE) and related traits in pig breeds. It identifies genetic relationships between FE and growth traits, and identifies SNPs and candidate genes associated with FE and FE-related traits. The study also identifies pathways involved in digestive and metabolic processes that are significantly associated with FE and FE-related traits. The results provide valuable information for the genomic selection of FE and FE-related traits in pigs.

Summary: This study compared the meat quality characteristics of Chinese local Jiaxing Black pigs and the Duroc x Duroc x Berkshire x Jiaxing Black crossbred pigs, revealing significant differences in carcass traits, growth rate, muscle nutrients, fatty acid levels, and gene expression between the two strains. The findings highlight the superiority of Jiaxing Black pigs in terms of meat quality but also identify areas in which crossbred pigs excel, providing insights for genetic enhancement in Chinese commercial pig breeding.

Summary: This study investigated the genetic basis of ear-related traits in maize using an immortalized F-2 population, identifying a total of 165 QTLs related to ear traits. Among them, 19 QTLs were considered reliable for nine ear-related traits. The results also revealed the presence of 35 genomic regions with pleiotropic effects and 17 heterotic loci.

Summary: The Huai pig is a well-known indigenous pig breed in China, with advantages in high intramuscular fat content and good meat quality. By analyzing the muscle transcriptomic profiles of Huai and Duroc pigs, significant differences in meat quality traits and amino acid content were found. The differentially expressed genes related to muscle fiber type, IMF deposition, lipid metabolism, and amino acid metabolism could be potential targets for improving pork yield and quality.

Summary: The study found that considering common litter environmental effects allows for more accurate estimation of genetic parameters for body measurement traits and meat production traits in pigs, while including maternal genetic effects in the model leads to larger standard errors in estimated genetic parameters.

Summary: A study in mice found that the SEC24A protein regulates the clearance of plasma cholesterol. Genome sequencing of Duroc pigs revealed a putative nonsense mutation in the SEC24A gene, but it was not associated with serum lipid concentrations. Careful manual curation of genetic mutations in pigs is recommended before experimental analysis.

Summary: Although genome-wide association studies (GWAS) based on single-marker analysis have limitations in terms of high false-positive rates and limited power to detect associations, the use of Bayesian methods and regional heritability mapping (RHM) have shown to be more effective in identifying important gene markers and reducing false-positive rates.

Summary: Fat depth (FD) and muscle depth (MD) are economically important traits for estimating carcass lean content in pig breeding. This study used sequence genotypes to assess the genetic architecture of body composition traits in commercial crossbred Pietrain pigs. Whole-genome sequence improved QTL detection and only additive effects contributed to the genetic architecture.

Summary: This study investigates cotton yield and fiber quality, revealing significant differences between different parent lines. The results indicate that most traits are negatively correlated with boll weight and lint percentage, while boll upper width, boll medium width, boll lower width, and boll length are positively correlated.
