Summary based on the indexed author abstract.

主要发现 Key findings

缓慢演化的雀鳝基因组保留祖先染色体结构,并揭示在人与真骨鱼直接比较中难以识别的保守调控序列。

The slowly evolving gar genome retains ancestral chromosome structures and reveals conserved regulatory elements obscured in direct human–teleost comparisons.

结论 Conclusions

雀鳝提供全基因组复制前的参照,有助于理解真骨鱼基因分工及人类调控元件。

Gar provides a pre-duplication reference for interpreting teleost gene partitioning and human regulatory elements.

主要发现 Key findings

功能基因组实验在斑点雀鳝及斑马鱼中识别出 HoxA 和 HoxD 增强子。雀鳝序列能在小鼠腕部与手指区域驱动与小鼠增强子近似的表达,鱼类增强子也在胸鳍远端发挥作用。

Functional genomic assays identified HoxA and HoxD enhancers in spotted gar and zebrafish. Gar sequences drove reporter expression in mouse wrist and digit regions closely resembling mouse enhancer activity, while fish enhancers also acted in distal pectoral fins.

结论 Conclusions

结果支持附肢远端调控机制的深度保守性,并与硬骨鱼远端辐状骨和四足动物腕部或指部结构同源的假说一致。

The findings support deep conservation of distal-appendage regulatory machinery and are consistent with homology between bony fish distal radials and tetrapod wrist or digit structures.
