刺丝管基因的水平转座及其在海鞘胚胎发育中的功能分析
Kun-Lung Li,Keisuke Nakashima,Kanako Hisata et al.
Kun-Lung Li et al.
Background: The Tunicata or Urochordata is the only animal group with the ability to synthesize cellulose directly and cellulose is a component of the tunic that covers the entire tunicate body. The genome of Ciona intest...
Feedback circuits are numerous in embryonic gene regulatory networks and offer a stabilizing influence on evolution of those networks [0.03%]
反馈回路在胚胎基因调控网络中普遍存在并可对这些网络的进化产生稳定作用
Abdull Jesus Massri,Brennan McDonald,Gregory A Wray et al.
Abdull Jesus Massri et al.
The developmental gene regulatory networks (dGRNs) of two sea urchin species, Lytechinus variegatus (Lv) and Strongylocentrotus purpuratus (Sp), have remained remarkably similar despite about 50 million years since a common ancestor. Hundre...
Transcriptomic analysis of cave, surface, and hybrid samples of the isopod Asellus aquaticus and identification of chromosomal location of candidate genes for cave phenotype evolution [0.03%]
基于秀丽阿塞尔OPSIS转录组分析及其洞穴表型进化候选基因的染色体定位识别
Haeli J Lomheim,Lizet Reyes Rodas,Lubna Mulla et al.
Haeli J Lomheim et al.
Background: Transcriptomic methods can be used to elucidate genes and pathways responsible for phenotypic differences between populations. Asellus aquaticus is a freshwater isopod crustacean with surface- and cave-dwellin...
Cartilage diversification and modularity drove the evolution of the ancestral vertebrate head skeleton [0.03%]
软骨分化和模块化驱动了祖先脊椎动物头部骨骼的进化
Zachary D Root,David Jandzik,Claire Gould et al.
Zachary D Root et al.
The vertebrate head skeleton has evolved a myriad of forms since their divergence from invertebrate chordates. The connection between novel gene expression and cell types is therefore of importance in this process. The transformation of the...
Early expression onset of tissue-specific effector genes during the specification process in sea urchin embryos [0.03%]
海胆胚胎在指定过程中的组织特异性效应子基因的早期表达启动
Shumpei Yamakawa,Atsuko Yamazaki,Yoshiaki Morino et al.
Shumpei Yamakawa et al.
Background: In the course of animal developmental processes, various tissues are differentiated through complex interactions within the gene regulatory network. As a general concept, differentiation has been considered to...
The embryology, metamorphosis, and muscle development of Schizocardium karankawa sp. nov. (Enteropneusta) from the Gulf of Mexico [0.03%]
墨西哥湾鲨鱼蠕虫Schizocardium karankawa sp. nov.(Enteropneusta)的胚胎学、变态和肌肉发育
Noura Jabr,Paul Gonzalez,Kevin M Kocot et al.
Noura Jabr et al.
Schizocardium karankawa sp. nov. has been collected from subtidal muds of the Laguna Madre, Texas, and the Mississippi coast, Gulf of Mexico. The Texas population is reproductive from early February to mid-April. Gametes are liberated by a ...
Shell field morphogenesis in the polyplacophoran mollusk Acanthochitona rubrolineata [0.03%]
具刺石鳖Acanthochitona rubrolineata八片壳胎壳的形成机制研究
Yuxiu Xia,Pin Huan,Baozhong Liu
Yuxiu Xia
Background: The polyplacophoran mollusks (chitons) possess serially arranged shell plates. This feature is unique among mollusks and believed to be essential to explore the evolution of mollusks as well as their shells. P...
Stability in gene expression and body-plan development leads to evolutionary conservation [0.03%]
基因表达和身体构型发育的稳定性导致了进化上的保守性
Yui Uchida,Hiroyuki Takeda,Chikara Furusawa et al.
Yui Uchida et al.
Background: Phenotypic evolution is mainly explained by selection for phenotypic variation arising from factors including mutation and environmental noise. Recent theoretical and experimental studies have suggested that p...
The role of non-additive gene action on gene expression variation in plant domestication [0.03%]
上位性基因作用在植物驯化过程中对基因表达变异的贡献
Erik Díaz-Valenzuela,Daniel Hernández-Ríos,Angélica Cibrián-Jaramillo
Erik Díaz-Valenzuela
Background: Plant domestication is a remarkable example of rapid phenotypic transformation of polygenic traits, such as organ size. Evidence from a handful of study cases suggests this transformation is due to gene regula...
