Molecular evolution of the ATP-binding cassette subfamily G member 2 gene subfamily and its paralogs in birds [0.03%]
鸟类ABCG2基因亚家族及其旁系同源基因的分子进化研究
Shengchao Ma,Hehe Liu,Wenqiang Sun et al.
Shengchao Ma et al.
Background: ATP-binding cassette (ABC) transporters are involved in the active transportation of various endogenous or exogenous substances. Two ABCG2 gene subfamily members have been identified in birds. A detailed compa...
Investigating cellular and molecular mechanisms of neurogenesis in Capitella teleta sheds light on the ancestor of Annelida [0.03%]
利用Capitella teleta探究神经元生成的细胞和分子机制为Annelida祖先提供启示
A Sur,A Renfro,P J Bergmann et al.
A Sur et al.
Background: Diverse architectures of nervous systems (NSs) such as a plexus in cnidarians or a more centralized nervous system (CNS) in insects and vertebrates are present across Metazoa, but it is unclear what selection ...
Genetic legacy of cultures indigenous to the Northeast Asian coast in mitochondrial genomes of nearly extinct maritime tribes [0.03%]
东北亚沿岸土著民族的遗传遗留在近灭绝的海洋部落线粒体基因组中
Stanislav V Dryomov,Elena B Starikovskaya,Azhar M Nazhmidenova et al.
Stanislav V Dryomov et al.
Background: We have described the diversity of complete mtDNA sequences from 'relic' groups of the Russian Far East, primarily the Nivkhi (who speak a language isolate with no clear relatedness to any others) and Oroki of...
Last Glacial Maximum led to community-wide population expansion in a montane songbird radiation in highland Papua New Guinea [0.03%]
末次冰盛期导致新几内亚高山曲翼莺类群的整个谱系种群扩张
Kritika M Garg,Balaji Chattopadhyay,Bonny Koane et al.
Kritika M Garg et al.
Background: Quaternary climate fluctuations are an engine of biotic diversification. Global cooling cycles, such as the Last Glacial Maximum (LGM), are known to have fragmented the ranges of higher-latitude fauna and flor...
Phylogenetic and spatial distribution of evolutionary diversification, isolation, and threat in turtles and crocodilians (non-avian archosauromorphs) [0.03%]
龟鳖和鳄类（非鸟类坚头类）的谱系与地理分布及其多样化、隔离与受威胁状况的关系研究
Timothy J Colston,Pallavi Kulkarni,Walter Jetz et al.
Timothy J Colston et al.
Background: The origin of turtles and crocodiles and their easily recognized body forms dates to the Triassic and Jurassic. Despite their long-term success, extant species diversity is low, and endangerment is extremely h...
What makes a fang? Phylogenetic and ecological controls on tooth evolution in rear-fanged snakes [0.03%]
侧槽蛇类的牙齿进化：系谱和生态因素的影响
Erin P Westeen,Andrew M Durso,Michael C Grundler et al.
Erin P Westeen et al.
Background: Fangs are a putative key innovation that revolutionized prey capture and feeding in snakes, and - along with their associated venom phenotypes - have made snakes perhaps the most medically-significant vertebra...
Contribution to understanding the evolution of holometaboly: transformation of internal head structures during the metamorphosis in the green lacewing Chrysopa pallens (Neuroptera: Chrysopidae) [0.03%]
全面理解全变态演化的重要进展：裳凤蝶柄眼时期头部分解与重建的过程及机制
Chenjing Zhao,Yuchen Ang,Mengqing Wang et al.
Chenjing Zhao et al.
Background: Metamorphosis remains one of the most complicated and poorly understood processes in insects. This is particularly so for the very dynamic transformations that take place within the pupal sheath of holometabol...
Counterbalancing the time-dependent effect on the human mitochondrial DNA molecular clock [0.03%]
校正人类线粒体DNA分子钟上的时间依赖性效应
Vicente M Cabrera
Vicente M Cabrera
Background: The molecular clock is an important genetic tool for estimating evolutionary timescales. However, the detection of a time-dependent effect on substitution rate estimates complicates its application. It has bee...
One species, two developmental modes: a case of geographic poecilogony in marine gastropods [0.03%]
一物种两发育模式——近海软体动物胎生分裂生殖地理学说的一个例证
Benedikt Wiggering,Marco T Neiber,Katharina Gebauer et al.
Benedikt Wiggering et al.
Background: Poecilogony, the presence of two developmental modes in the same animal species, is a rare phenomenon. Few cases of poecilogony have been suggested for marine invertebrates including molluscs and even less sto...
Prebiotic competition and evolution in self-replicating polynucleotides can explain the properties of DNA/RNA in modern living systems [0.03%]
自复制多核苷酸中的增殖竞争和进化可以解释现代生命系统中DNA/RNA的性质
Hemachander Subramanian,Joel Brown,Robert Gatenby
Hemachander Subramanian
Background: We hypothesize prebiotic evolution of self-replicating macro-molecules (Alberts, Molecular biology of the cell, 2015; Orgel, Crit Rev Biochem Mol Biol 39:99-123, 2004; Hud, Nat Commun 9:5171) favoured the cons...
