摘要

GDF9 S395F和S427R突变类型可提高杂合子的排卵率，而同合子则会导致不育。本研究对与绵羊产仔数（LS）相关的GDF9和BMP15 SNPs进行了荟萃分析。结果显示，模拟了 GDF9 R453H、S395F 和 S427R 的分子识别，研究了它们对 GDF9 二聚体的影响。突变杂合子的S395F和S427R二聚体结合能力得到改善，从而提高了LS。突变型同源二聚体的结合能力降低，导致不育。该研究结果将为动物育种提供重要参考。

Regulation of litter size in sheep (Ovis aries) by the GDF9 and BMP15 genes

The mutation types GDF9 S395F and S427R increase the ovulation rate in heterozygotes, while the homozygous form leads to infertility. This study presents a meta-analysis of GDF9 and BMP15 SNPs related to sheep litter size (LS). The results showed that simulation of the molecular recognition of GDF9 R453H, S395F, and S427R was performed to study the effect on the GDF9 dimer. S395F and S427R dimer binding ability of mutant heterozygotes was improved, thereby improving LS. The binding ability of mutant homozygous dimers was reduced, resulting in infertility. The results of this study will provide important references for animal breeding.
