Project description:Domestication of pig results in modifications of many traits, including fatness traits, which are important in pig production since they have effect on meat quality, fattening efficiency, reproduction and immunity.In this study, we investigate 3D genome organization and transcriptomic characterization of adipose tissues (ATs) between wild boars and Bama pig, a typical indigenous domestic pig in China, to uncover molecular mechanisms of fatness-phenotypic shifts.
Project description:The importance of the adrenal gland in regard to lactation and reproduction in cattle has been recognized early. Due to consumers interest in animal welfare and the impact of stress on economically important traits in farm animals the adrenal gland and its function within the stress response is still of increasing interest. Especially the molecular mechanisms and pathways that are involved in the stress related effects on economically important traits in farm animals are not studied in full detail. Gene expression is an important mechanism underlying complex traits. Genetic variants affecting the transcript abundance are thought to affect the manifestation of an expressed phenotype. Therefore we investigated the genetic background of adrenocortical gene expression by applying an adaptive linear rank test to identify genome-wide expression quantitative trait loci (eQTL) for adrenal cortex transcripts in cattle.
Project description:The unique fat storage and metabolic characteristics of goose liver is an important model for studying lipid metabolism in animals or humans. In this study, RNA sequencing technology was used to obtain the liver transcriptome of Sichuan white goose with significant weight difference in the same population, and differentially expressed genes and their pathways were identified, which may help to understand the mechanism of goose weight change. In addition, the identified candidate genes may be useful for molecular breeding of geese.
