About this Research Topic
Due to the great scientific significance and application value, the study of the genetic foundation of economic traits and selective breeding of pigs has been carried out since the beginning of the 20th century. The completion of the multiple pig genome projects constructs a comprehensive list of all genes of pig. Additionally, a significant number of genes and loci have been identified in pigs. However, years of extensive research have shown that only a few major genes and loci are useful for breeding, and the situation is far more complex than a simple list of genes and loci. Meat quality and production performance exhibit apparent antagonism. The genetic foundation meat quality and production performance remain not well elucidated. Intensive exploration genetic mechanisms of meat quality and production performance of pigs remain the focus of our research.
Because only a few major genes and loci can be used for breeding, we will concentrate on the genetic mechanisms underlying differences between different strains of the same variety or between different varieties in economic traits, such as growth rate, intestinal digestibility (feed to meat ratio), meat production performance, meat quality, and other factors. Furthermore, we will pay attention to analyze the genetic mechanism and molecular regulatory networks of meat quality and production performance in pigs at the levels of DNA, RNA, proteins, and chromatin using various methods such as transcriptomics, proteomics, metabolomics, monocyteomics and multi-omics joint analysis. In addition, the identification of new candidate genes related to meat quality and production performance in pigs will also be a key focus.
This research Topic will focus on the genetic mechanism of meat quality and production performance in pig. We welcome the submission of original research articles, perspective, review, and mini-reviews related to, but not limited to, the following topics:
• Discovery of new candidate genes and genetic loci related to meat quality and production performance in pigs
• Research on the genetic mechanism and molecular regulatory network of meat quality and production performance in pig
• Investigation of the roles and contributions of genes and molecular markers in the formation of meat quality and production performance in pigs
• Application of genes and molecular markers in marker-assisted selection and genome-wide selection in pigs
