091-解码蚂蚁社会性状的基因密码🐜

04 Sep 2025

Description

这篇研究文章深入探讨了蚂蚁社会进化背后的遗传机制,主要通过对163种蚂蚁基因组的广泛比较分析。文章阐述了蚂蚁等级分化的群落如何起源并成为陆地生态系统的主导力量,其成功归因于类似于多细胞生物体体细胞的劳动分工。研究团队通过全球蚂蚁基因组联盟(GAGA)收集高质量基因组数据,揭示了染色体重新排列与物种多样性的关联,并确定了与社会性状相关的基因家族进化和选择压力。此外,文章还分析了激素信号通路和基因表达模式在蚁后/工蚁分化中的作用,为理解蚂蚁独特的超个体组织提供了全面的基因组视角。References: Vizueta J, Xiong Z, Ding G, et al.
