Plasmids play a crucial role in the evolution of bacterial genomes by mediating horizontal gene transfer. However, the origin and evolution of most plasmids remains unclear, especially for megaplasmids. The Bacillus subtilis -group and the Bacillus cereus -group are two well-studied groups of species in the genus Bacillus. Bacteria in this genus can produce a highly resistant cell type, the spore, which is encased Authors: Hong Qin and Adam Driks. The non-classical class II DM molecul Hypodontus macropi is a common intestinal nematode of a range of kangaroos and wallabies macropodid marsupials.

The increasing number of assembled mammalian genomes makes it possible to compare genome organisation across mammalian lineages and reconstruct chromosomes of the ancestral marsupial and therian marsupial and Nucleotide and amino acid substitution tendencies are characteristic of each species, organelle, and protein family. Hence, various empirical amino acid substitution rate matrices have needed to be estimated f Authors: Sanzo Miyazawa.

Endogenous retroviruses ERVs are genomic elements of retroviral origin that are present in the genomes of almost all vertebrates. In cattle, more than 13, elements related to ERVs have been detected, and The miR subfamily belongs to an X-linked primate-specific miR cluster.

Across primate species, there have been several duplication events and different species each possess a variety of miR copi Host-parasite coevolution is generally believed to follow Red Queen dynamics consisting of ongoing oscillations in the frequencies of interacting host and parasite alleles. This belief is founded on previous t Within the complex metazoan phylogeny, the relationships of the three lophophorate lineages, ectoprocts, brachiopods and phoronids, are particularly elusive.

To shed further light on this issue, we present phy Pyura chilensis , a tunicate commercially exploited as food resource in Chile, is subject to management strategies, including restocking. The goal of this study was to examine the genetic structure of P. Placental mammals display a huge range of life history traits, including size, longevity, metabolic rate and germ line generation time.

Although a number of general trends have been proposed between these trai One of the most striking features of avian vision is the variation in spectral sensitivity of the short wavelength sensitive SWS1 opsins, which can be divided into two sub-types: violet- and UV- sensitive V The Alpine region harbours one of the most diverse subterranean faunas in the world, with many species showing extreme morphological modifications.

The ground beetles of tribe Trechini Coleoptera, Carabidae Positive multi-locus heterozygosity-fitness correlations have been observed in a number of natural populations. They have been explained by the correlation between heterozygosity and inbreeding, and the negati To survive in a hostile environment, insects have evolved an innate immune system to defend against infection.

Studies have shown that natural selection may drive the evolution of immune system-related protein A major goal of molecular evolution is to determine how natural selection has shaped the evolution of a gene.

We wish to understand how sex and recombination affect endogenous retroviral insertion and deletion. While theory suggests that the risk of ectopic recombination will limit the accumulation of repetitive DNA i This view has however been challenged during the last decade. This is the case of the Protein phosphatase 1 regula China is characterized by complex topographic structure and dramatic palaeoclimatic changes, making species biogeography studies particularly interesting.

Previous researchers have also demonstrated multiple s Hydrophobins are small secreted cysteine-rich proteins that play diverse roles during different phases of fungal life cycle. In basidiomycetes, hydrophobin-encoding genes often form large multigene families wi Whether male and female gametes are produced by single or separate individuals shapes plant mating and hence patterns of genetic diversity among and within populations.

Together with the dim-light receptor rhodopsin RH Among the winged insects Pterygota the Odonata dragon- and damselflies are special for several reasons. They are strictly aerial predators showing remarkable flight abilities and their thorax morphology di Molecular phylogenetic analyses have revealed that Hexapoda and Crustacea form a common clade the Pancrustacea , which is now widely accepted among zoologists; however, the origin of Hexapoda remains unresolv It is often assumed that evolution takes place on very large timescales. Countering this assumption, rapid evolutionary dynamics are increasingly documented in biological systems, e.

Species are the fundamental units in evolutionary biology. However, defining them as evolutionary independent lineages requires integration of several independent sources of information in order to develop rob The genus Uropsilus comprises a group of terrestrial, montane mammals endemic to the Hengduan and adjacent mountains. These animals are the most primitive living talpids.

Evolutionary origins of sensation in metazoans: functional evidence for a new sensory organ in sponges One of the hallmarks of multicellular organisms is the ability of their cells to trigger responses to the environment in a coordinated manner.

Functional basis of ecological divergence in sympatric stickleback The evolution of ecological divergence in closely related species is a key component of adaptive radiation. Cophylogenetic relationships between Anicetus parasitoids Hymenoptera: Encyrtidae and their scale insect hosts Hemiptera: Coccidae Numerous studies have investigated cospeciation between parasites and their hosts, but there have been few studies concerning parasitoids and insect hosts.

Inferring explicit weighted consensus networks to represent alternative evolutionary histories The advent of molecular biology techniques and constant increase in availability of genetic material have triggered the development of many phylogenetic tree inference methods. Explosive diversification following a benthic to pelagic shift in freshwater fishes Interspecific divergence along a benthic to pelagic habitat axis is ubiquitous in freshwater fishes inhabiting lentic environments.
