摘要

影响多种性状的基因组区域的变异会如何调节不同生命阶段的适应性？Aykanat 等人（2024 年）的研究表明，与成熟年龄相关的两个大效应位点 six6 和 vgll3 通过营养依赖性间接遗传效应影响野生大西洋鲑（Salmo salar）的存活率。具体来说，亲本 vgll3 中的晚熟等位基因和母本 six6 中的早熟等位基因会增加高营养条件下早期生命的存活率。

Digest: Large-effect loci involved in maturation timing affect the early survival of Atlantic salmon.

How might variations in genomic regions that impact many traits modulate fitness across different life stages? Aykanat et al. (2024) show that two large-effect loci associated with age at maturity, six6 and vgll3, impact the survival of wild Atlantic salmon (Salmo salar) through nutrient-dependent, indirect genetic effects. Specifically, the late maturation allele in parental vgll3, and the early maturation allele in maternal six6, increase survival in early life under high nutrient conditions.
