Nature全文 PDF三个染色体级鸭基因组组装揭示驯化过程中的基因组变异
Three chromosome-level duck genome assemblies provide insights into genomic variation during domestication
Nature communications · 2021
依据索引收录的作者摘要概括。
Summary based on the indexed author abstract.
主要发现 Key findings
绿头鸭与肉用、蛋用品系的基因组找回许多此前缺失的鸟类基因，并提供超过3600万个群体变异及脂肪沉积候选机制。
Mallard and domestic duck assemblies recover many previously missing avian genes and identify more than 36 million population variants plus candidate mechanisms of fat deposition.
结论 Conclusions
研究改进鸟类基因组资源并解释部分驯化差异，但候选变异的作用需逐项验证。
The study improves avian genomic resources and explains aspects of domestication, while individual candidate variants require validation.
Science仅摘要 Abstract onlyBMP 信号对趾间凋亡和鳞片形成的必要作用
Requirement for BMP signaling in interdigital apoptosis and scale formation.
Science · 1996
依据作者摘要概括。
Inspected PubMed abstract indexed by Europe PMC; archived full text does not imply full-text review.
主要发现 Key findings
阻断鸡胚后肢 BMP 信号会减少趾间凋亡、产生蹼足并使鳞片转为羽毛。与鸭趾间组织的比较将信号差异与保留蹼膜联系起来。
Blocking BMP signaling in embryonic chicken hindlimbs reduces interdigital apoptosis, produces webbed feet and transforms scales into feathers. Comparisons with duck interdigits link signaling differences to retained webbing.
结论 Conclusions
发育信号变化可造成羊膜动物附肢形态的显著差异，包括指趾分离及皮肤附属结构。
Changes in developmental signaling can generate major differences in amniote appendage form, including digit separation and skin appendages.
Science仅摘要 Abstract only喙形态的细胞与分子起源
The cellular and molecular origins of beak morphology.
Science · 2003
依据作者摘要概括。
Inspected PubMed abstract indexed by Europe PMC; archived full text does not imply full-text review.
主要发现 Key findings
在鸭与鹌鹑胚胎间交换神经嵴细胞，可使宿主形成类似供体的喙；供体细胞执行自身程序，并改变相邻宿主组织的基因表达。
Neural-crest exchanges between duck and quail embryos produced donor-like beaks in host embryos. Donor cells followed autonomous programs and altered gene expression in adjacent host tissues.
结论 Conclusions
神经嵴细胞提供指导性信息，协调其他组织并促成物种特异的喙形差异。
Neural-crest cells supply instructive information that coordinates other tissues and contributes to species-specific beak variation.
