The diversity of functional genes and the related processes are important issues for conservation biology. This is especially relevant for populations that have suffered from demographic reduction as a consequence of the processes of postgl...
Discordance in variation of the ITS region and the mitochondrial COI gene in the subterranean amphipod Crangonyx islandicus [0.03%]
次地下端足类动物Crangonyx islandicus中ITS区和线粒体COI基因变异的不协调性分析

Etienne Kornobis
The amphipod Crangonyx islandicus is a recently discovered species endemic to Iceland. Populations of C. islandicus are highly structured geographically and genetically. The COI and 16S mitochondrial genes confine six monophyletic groups wh...
Positive Darwinian selection drives the evolution of the morphology-related gene, EPCAM, in particularly species-rich lineages of African cichlid fishes [0.03%]
正向达尔文选择驱动非洲丽鱼属鱼类物种丰富谱系形态相关基因EPCAM的进化

Shaohua Fan
The study of genetic evolution within the context of adaptive radiations offers insights to genes and selection pressures that result in rapid morphological change. Cichlid fishes are very species-rich and variable in coloration, behavior, ...
Fast side chain replacement in proteins using a coarse-grained approach for evaluating the effects of mutation during evolution [0.03%]
基于粗粒化方法的蛋白质侧链快速替换及在进化过程中评估突变效应的新算法

For high-throughput structural genomic and evolutionary bioinformatics approaches, there is a clear need for fast methods to evaluate substitutions structurally. Coarse-grained methods are both powerful and fast, and a coarse-grained approa...
A model of proto-anti-codon RNA enzymes requiring L-amino acid homochirality [0.03%]

All living organisms encode the 20 natural amino acid units of polypeptides using a universal scheme of triplet nucleotide "codons". Disparate features of this codon scheme are potentially informative of early molecular evolution: (i) the a...
Absence of positive selection on centromeric histones in Tetrahymena suggests unsuppressed centromere: drive in lineages lacking male meiosis [0.03%]
四膜虫染色体组中心粒组蛋白不存在正向选择表明缺失雄性减数分裂的谱系中心粒-驱动未被抑制
Nels C Elde,Kevin C Roach,Meng-Chao Yao et al.
Nels C Elde et al.
Centromere-drive is a process where centromeres compete for transmission through asymmetric "female" meiosis for inclusion into the oocyte. In symmetric "male" meiosis, all meiotic products form viable germ cells. Therefore, the primary inc...
Evolution of vertebrate immunity: sequence and functional analysis of the SEFIR domain family member Act1 [0.03%]
脊椎动物免疫系统的进化：含SEFIR结构域蛋白Act1的序列和功能分析

Grigory Ryzhakov
SEF/IL-17R/CIKS/ACT1 homology (SEFIR) domain containing proteins, which include the IL-17 receptors and an adaptor protein Act1, have essential roles in vertebrate immunity. However, the molecular mechanisms of Act1 function remain largely ...
Molecular evolution of mollusc shell proteins: insights from proteomic analysis of the edible mussel Mytilus [0.03%]
软体动物贝壳蛋白的分子进化：来自食用贻贝Mytilus的蛋白质组分析的新见解
Benjamin Marie,Nathalie Le Roy,Isabelle Zanella-Cléon et al.
Benjamin Marie et al.
Shell matrix proteins (SMPs) that are embedded within calcified layers of mollusc shells are believed to play an essential role in controlling the biomineral synthesis and in increasing its mechanical properties. Among the wide diversity of...
Co-variation among major classes of LRR-encoding genes in two pairs of plant species [0.03%]
两组植物种间LRR编码基因主要类型间的协同变异

Jiao Wang et al.
NBS-LRR (nucleotide-binding site-leucine-rich repeat), LRR-RLK (LRR-receptor-like kinase), and LRR-only are the three major LRR-encoding genes. Owing to the crucial role played by them in plant resistance, development, and growth, extensive...

Protein products of highly expressed genes tend to favor amino acids that have lower average biosynthetic costs (i.e., they exhibit metabolic efficiency). While this trend has been observed in several studies, the specific sites where cost-...
