Abstract
Sperm adhesion molecule 1(SPAM1) is a vital candidate gene that plays an important role in fertilization and hatchability of geese. In this study, we investigated for the first time the genetic variation of the SPAM1 gene and its association with egg production trait in Yangzhou geese. By using the direct sequencing technique, we detected three single nucleotide polymorphisms, g206 G>C, c123 T>A, and c159 T>C, located in the promoter and exon one regions, respectively. Six alleles and nine genotypes (GG, CC, GC, TT, TA, AA, TT, TC and CC) were obtained, respectively. The results indicated that the GG (g206 G>C) genotype had a significantly higher egg production rate during the 34-week egg-laying period. In the case of the SNPs c123 T > A and c159 T > C individuals with the AA and TT genotypes produced more eggs number, respectively. The SPAM 1 gene was highly expressed in the oviduct, abdominal fat, ovary and small intestine tissues. The mRNA expression level in the oviduct and ovary indicated that the geese with GG genotype recorded significantly lower expression levels (0.72 ± 0.02; 0.93 ± 0.02) compared to the geese with CC genotype (1.27 ± 0.19, 1.11 ± 0.06), respectively. Transcriptional activity results showed that both constructed vectors (pGL3-328G and pGL3-333C) had higher and more significant luciferase activity than the pGL3-basic vector. Future studies in Yangzhou and other native breeds of geese may be required to validate the association between these polymorphisms and egg production traits.

期刊介绍:
Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
