“…In this study, KEGG enrichment analysis revealed that the pathways significantly enriched at different periods were mostly related to energy and amino acid metabolism, such as cysteine and methionine metabolism, lysine degradation, and arginine biosynthesis. In a transcriptomic study of muscle development in Zhedong white geese, the differential genes were similarly found to be mostly associated with metabolic pathways such as glycolysis/gluconeogenesis ( Hu et al, 2022 ). Through the comparative analysis of differential pathways at different stages, we screened 5 pathways related to muscle growth and development in Erythrina geese, namely: adhesion plaques, extracellular matrix receptor interactions, tight junctions, TGF-β signaling pathway, and MAPK signaling pathway.…”

“…These studies aim to uncover the molecular mechanisms that regulate their growth traits ( Qian et al, 2023 ; Zhang et al, 2023 ; Zhao et al, 2023 ). Hu et al (2022) found that short photoperiod significantly promoted muscle development and significantly improved the redness of goose muscle, and identified the possible involvement of glycolysis/gluconeogenesis, calcium signaling pathway, and PI3K-Akt signaling pathway in the regulation of muscle development and meat color in geese by light through RNA-seq analysis. Tang et al (2023) investigated transcriptional changes in the leg muscles of the Shitou goose and the Wuzong goose during a period of high growth rate and found that many DEGs have potential growth functions, such as CXCL12, SSTR4, FABP5, SLC2A1, MYLK4, and EIF4E3.…”

Background Domestic goose breeds are descended from either the Swan goose (Anser cygnoides) or the Greylag goose (Anser anser), exhibiting variations in body size, reproductive performance, egg production, feather color, and other phenotypic traits. Constructing a pan-genome facilitates a thorough identification of genetic variations, thereby deepening our comprehension of the molecular mechanisms underlying genetic diversity and phenotypic variability. Results To comprehensively facilitate population genomic and pan-genomic analyses in geese, we embarked on the task of 659 geese whole genome resequencing data and compiling a database of 155 RNA-seq samples. By constructing the pan-genome for geese, we generated non-reference contigs totaling 612 Mb, unveiling a collection of 2,813 novel genes and pinpointing 15,567 core genes, 1,324 softcore genes, 2,734 shell genes, and 878 cloud genes in goose genomes. Furthermore, we detected an 81.97 Mb genomic region showing signs of genome selection, encompassing the TGFBR2 gene correlated with variations in body weight among geese. Genome-wide association studies utilizing single nucleotide polymorphisms (SNPs) and presence-absence variation revealed significant genomic associations with various goose meat quality, reproductive, and body composition traits. For instance, a gene encoding the SVEP1 protein was linked to carcass oblique length, and a distinct gene-CDS haplotype of the SVEP1 gene exhibited an association with carcass oblique length. Notably, the pan-genome analysis revealed enrichment of variable genes in the “hair follicle maturation” Gene Ontology term, potentially linked to the selection of feather-related traits in geese. A gene presence-absence variation analysis suggested a reduced frequency of genes associated with “regulation of heart contraction” in domesticated geese compared to their wild counterparts. Our study provided novel insights into gene expression features and functions by integrating gene expression patterns across multiple organs and tissues in geese and analyzing population variation. Conclusion This accomplishment originates from the discernment of a multitude of selection signals and candidate genes associated with a wide array of traits, thereby markedly enhancing our understanding of the processes underlying domestication and breeding in geese. Moreover, assembling the pan-genome for geese has yielded a comprehensive apprehension of the goose genome, establishing it as an indispensable asset poised to offer innovative viewpoints and make substantial contributions to future geese breeding initiatives.
