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: 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: 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: This study aimed to identify major quantitative trait loci (QTL) for resistance to black point disease in wheat and develop molecular markers for marker-assisted selection (MAS). A recombinant inbred line (RIL) population was evaluated for resistance to Bipolaris sorokiniana, and resistant and susceptible bulks were genotyped using a wheat 660 K SNP array. Several QTL for black point resistance were identified on three chromosomes, with potential markers for MAS-based breeding. These findings contribute to our understanding and potential improvement of black point disease management in wheat production.

Summary: The proposed Methylation Random Field (MRF) method offers advantages in detecting Methylation Quantitative Trait Loci (mQTLs) by utilizing a beta distribution and considering multiple common and rare genetic variants. Through simulations and application to a study on congenital heart defects, the MRF demonstrated improved power in detecting rare variants, especially with small sample sizes. This tool is useful for identifying novel mQTLs, particularly in studies with limited sample sizes.

Summary: This study investigated the changes in chlorophyll content in wheat flag leaves under different phosphorus conditions and identified 157 QTLs associated with this trait. Six major QTLs were detected under multiple phosphorus conditions, and two novel major QTLs were discovered. Additionally, SNP markers closely linked to these QTLs were validated.

Summary: This study investigated the phenotypes of fatty acid composition in different tissues of pigs and their associations with growth and carcass traits. The results showed that the fatty acid composition traits were significantly correlated with growth and carcass traits, with a stronger correlation in backfat compared to the longissimus lumborum. Polyunsaturated fatty acid traits were found to have the strongest correlation with growth and carcass traits, suggesting a link between the metabolism of polyunsaturated fatty acids in muscle and fat tissues and the phenotypes of growth and carcass.

Summary: The study investigated the fatty acid composition in different tissues of pigs and found that there are significant differences between backfat and longissimus lumborum tissues. The fatty acid composition traits were also found to be closely related to growth and carcass traits, with stronger correlations observed in backfat.

Summary: This study aimed to identify major quantitative trait loci (QTL) for resistance to black point disease in wheat and develop molecular markers for marker-assisted selection (MAS). Through artificial inoculation and genotyping, two new QTL for black point resistance were discovered on chromosomes 4A and 5A. These findings provide potential markers for MAS-based breeding and contribute to the understanding of the genetic basis of resistance to black point disease in wheat.

Summary: We estimated genetic parameters for pork production and litter performance traits of Landrace, Large White, and Duroc pigs in Japan. The heritability of pork production traits was estimated to be 0.4-0.5 and for litter performance traits, it was below 0.2. Genetic correlation between daily gain and backfat thickness was small, while that between pork production traits and litter performance traits ranged from negligible to moderate. The results highlight the importance of carefully considering the statistical model used for analysis.

Summary: This study focused on small-effect quantitative trait loci (QTLs) related to grain size in rice. By developing residual heterozygous populations and conducting genotyping and phenotyping, two genetically linked small-effect QTLs (qGS7.1 and qTGW7.2b) were mapped and candidate genes were identified. The study also revealed the impact of these QTLs on cell expansion, leading to changes in grain width. In addition, a QTL (qTGW7.2b) was identified to significantly affect grain length and width, but had little effect on grain weight.
