Abstract Background Gene flow is crucial for enhancing economic traits of livestock. In China, breeders have used hybridization strategies for decades to improve livestock performance. Here, we performed whole-genome sequencing of a native Chinese Lijiang pig (LJP) breed. By integrating previously published data, we explored the genetic structure and introgression of genetic components from commercial European pigs (EP) into the LJP, and examined the impact of this introgression on phenotypic traits. Results Our analysis revealed significant introgression of EP breeds into the LJP and other domestic pig breeds in China. Using a haplotype-based approach, we quantified introgression levels and compared EP to LJP and other Chinese domestic pigs. The results show that EP introgression is widely prevalent in Chinese domestic pigs, although there are significant differences between breeds. We propose that LJP could potentially act as a mediator for the transmission of EP haplotypes. We also examined the correlation between EP introgression and the number of thoracic vertebrae in LJP and identified VRTN and STUM as candidate genes for this trait. Conclusions Our study provides evidence of introgressed European haplotypes in the LJP breed and describes the potential role of EP introgression on phenotypic changes of this indigenous breed.

Este trabajo pretende mostrar el impacto que generó la censura en la traducción y recepción de obras occidentales vertidas al chino en la época contemporánea. Los análisis bibliográfico y lingüístico textual apuntan una marcada complicidad entre traductores y censores, dando pie a una tendencia traductológica que no siempre silencia los contenidos polémicos, sino que más bien opta por crear, mediante la adulteración de la obra original, discursos favorables a los intereses del régimen político chino. A pesar de ello, el análisis paratextual nos permite apreciar cómo en los casos seleccionados se han logrado deslizar mensajes claramente divergentes de la ideología dominante. Para precisar el alcance de este fenómeno sobre la traducción, en el futuro será necesario aumentar, lógicamente, el corpus de análisis y ampliar el espectro a todo tipo de géneros literarios.
