Although intron loss and gain have been widely observed, their mechanisms are still to be determined. In four Aspergillus genomes, we found 204 cases of intron loss and 84 cases of intron gain. Using this data, we tested common hypotheses o...
AVPR1A sequence variation in monogamous owl monkeys (Aotus azarai) and its implications for the evolution of platyrrhine social behavior [0.03%]
单配生活的夜猴(Aotus azarai)中AVPR1A序列的变异及其对新世界猴社会行为进化的启示

The arginine vasopressin V1a receptor gene (AVPR1A) has been implicated in increased partner preference and pair bonding behavior in mammalian lineages. This observation is of considerable importance for studies of social monogamy, which on...
Phylogenetic analysis reveals rapid evolutionary dynamics in the plant RNA virus genus tobamovirus [0.03%]
系统进化分析揭示植物RNA病毒属tobamovirus的快速演化动态

Early studies on the evolutionary dynamics of plant RNA viruses suggested that they may evolve more slowly than their animal counterparts, sometimes dramatically so. However, these estimates were often based on an assumption of virus-host c...

As far as protein-coding genes are concerned, there is a non-zero probability that at least one of the five possible overlapping sequences of any gene will contain an open-reading frame (ORF) of a length that may be suitable for coding a fu...
Evolution of enzymatic activities of testis-specific short-chain dehydrogenase/reductase in Drosophila [0.03%]

The testis-specific gene Jingwei (jgw) is a newly evolved short-chain dehydrogenase/reductase in Drosophila. Preliminary substrate screening indicated that JGW prefers long-chain primary alcohols as substrates, including several exotic alco...
Genes devoid of full-length transposable element insertions are involved in development and in the regulation of transcription in human and closely related species [0.03%]
无全长转座子插入且在人类及其近缘物种中参与发育和转录调控的基因

Transposable elements (TEs) are major components of mammalian genomes, and their impact on genome evolution is now well established. In recent years several findings have shown that they are associated with the expression level and function...

Species identification is one of the most important issues in biological studies. Due to recent increases in the amount of genomic information available and the development of DNA sequencing technologies, the applicability of using DNA sequ...

Genome variation studies in Plasmodium falciparum have focused on SNPs and, more recently, large-scale copy number polymorphisms and ectopic rearrangements. Here, we examine another source of variation: variable number tandem repeats (VNTRs...

Rapid evolution has been identified for many reproductive genes and recent studies have combined phylogenetic tests and information on species mating systems to test sexual selection. Here we examined the molecular evolution of the ADAM gen...
Explosive expansion of betagamma-crystallin genes in the ancestral vertebrate [0.03%]
脊椎动物祖先中的β-γ晶状体基因爆炸式扩张

Guido Kappé et al.
In jawed vertebrates, betagamma-crystallins are restricted to the eye lens and thus excellent markers of lens evolution. These betagamma-crystallins are four Greek key motifs/two domain proteins, whereas the urochordate betagamma-crystallin...
