Genome-wide DNA methylation differences between conservation and breeding populations of Shaoxing ducks

DNA methylation in poultry: a review

“…Thirty-five differentially methylated genes were identified and these genes were closely related to production performance. In addition, ATP2B1 and ATP2B2 genes related to eggshell quality were also identified as differentially methylated, which could be used as molecular markers to improve eggshell quality in the future [ 21 ]. Incubation temperature also has long-term effects on bird embryo development and its effect on DNA methylation was investigated by increasing the incubation temperature from 37.8 to 38.8 ºC at ED (embryonic stage) 1–10, ED10–20 and ED20–27.…”

“…DNA methylation has been widely utilized in poultry species [15][16][17][18][19][20][21]. For example, in the DNA methylation map of broilers, there are more hypomethylated regions in the genome, and CGIs (CpG islands) has the largest distribution in the gene promoter region, indicating that the hypomethylation of CGIs methylation and muscle developing-related genes is involved in the rapid muscle development of broilers.…”

Whole-genome resequencing to unveil genetic characteristics and selection signatures of specific pathogen-free ducks

“…Herein we present WGRS-based analyses involving 3 representative SPF experimental duck varieties: Jinding ducks ( JD ), Shaoxing ducks ( SX ), and Fujian Shanma ducks ( SM ). They represent local elite duck breeds in Southeast China and are often used as ancestral generations to breed new varieties as they show excellent fertility and egg-laying performance ( Lin et al, 2014 ; Wang et al, 2017 ; Xu et al, 2022 ).…”
