The complete mitochondrial genome of the Ctenophore Beroe cucumis, a mitochondrial genome showing rapid evolutionary rates.

ABSTRACT: We described the complete mitochondrial genome of the Ctenophore Beroe cucumis, which is a circular molecule of 10,487?bp in length. The new mitochondrial genome comprised only 12 genes, making it one of the smallest animals' mtDNA. Both nucleotide substitution and gene order rearrangements exhibited extreme high evolutionary rate in mitogenomes of Ctenophore. The phylogenetic analysis based on mitogenomics failed to reveal the basal position of Ctenophore within metazoan, owing to the extreme evolutionary rate. Based on the available Ctenophora mitogenomes, we found the optimized primers designed by Geller et al. for DNA barcoding suited for the taxon.

Rapid evolution of the compact and unusual mitochondrial genome in the ctenophore, Pleurobrachia bachei.

Project description:Ctenophores are one of the most basally branching lineages of metazoans with the largest mitochondrial organelles in the animal kingdom. We sequenced the mitochondrial (mtDNA) genome from the Pacific cidipid ctenophore, Pleurobrachia bachei. The circular mitochondrial genome is 11,016 nts, with only 12 genes, and one of the smallest metazoan mtDNA genomes recorded. The protein coding genes are intronless cox1-3, cob, nad1, 3, 4, 4L and 5. The nad2 and 6 genes are represented as short fragments whereas the atp6 gene was found in the nuclear genome. Only the large ribosomal RNA subunit and two tRNAs were present with possibly the small subunit unidentifiable due to extensive fragmentation. The observed unique features of this mitochondrial genome suggest that nuclear and mitochondrial genomes have evolved at very different rates. This reduced mtDNA genome sharply contrasts with the very large sizes of mtDNA found in other basal metazoans including Porifera (sponges), and Placozoa (Trichoplax).

Complete sequence of mitochondrial genome of Cucumis melo L.

Project description:Cucumis melo L. is one of the most important fruit-type vegetables in the world. This genome is divided into a main loop and two small loops. The length of the main loop is 2,709,526 bp, and the two small loops are 149,555 bp and 47,592 bp long, respectively. There are 88 coding genes in the melon mitochondrial genome, including 40 protein-coding genes (which accounted for about 1.23% of the whole genome), 8 rRNAs, and 40 tRNAs. The total length of rRNAs and tRNAs spans 0.31% of the total genome sequence. Among the 88 mitochondrial coding genes, only 5 tRNAs were located into the second largest circular DNA molecule. The complete mitogenome sequence provided herein would help understand C. melo evolution.

The ctenophore genome and the evolutionary origins of neural systems.

Project description:The origins of neural systems remain unresolved. In contrast to other basal metazoans, ctenophores (comb jellies) have both complex nervous and mesoderm-derived muscular systems. These holoplanktonic predators also have sophisticated ciliated locomotion, behaviour and distinct development. Here we present the draft genome of Pleurobrachia bachei, Pacific sea gooseberry, together with ten other ctenophore transcriptomes, and show that they are remarkably distinct from other animal genomes in their content of neurogenic, immune and developmental genes. Our integrative analyses place Ctenophora as the earliest lineage within Metazoa. This hypothesis is supported by comparative analysis of multiple gene families, including the apparent absence of HOX genes, canonical microRNA machinery, and reduced immune complement in ctenophores. Although two distinct nervous systems are well recognized in ctenophores, many bilaterian neuron-specific genes and genes of 'classical' neurotransmitter pathways either are absent or, if present, are not expressed in neurons. Our metabolomic and physiological data are consistent with the hypothesis that ctenophore neural systems, and possibly muscle specification, evolved independently from those in other animals.

The complete mitochondrial genome of Gossypium hirsutum and evolutionary analysis of higher plant mitochondrial genomes.

Project description:BackgroundMitochondria are the main manufacturers of cellular ATP in eukaryotes. The plant mitochondrial genome contains large number of foreign DNA and repeated sequences undergone frequently intramolecular recombination. Upland Cotton (Gossypium hirsutum L.) is one of the main natural fiber crops and also an important oil-producing plant in the world. Sequencing of the cotton mitochondrial (mt) genome could be helpful for the evolution research of plant mt genomes.Methodology/principal findingsWe utilized 454 technology for sequencing and combined with Fosmid library of the Gossypium hirsutum mt genome screening and positive clones sequencing and conducted a series of evolutionary analysis on Cycas taitungensis and 24 angiosperms mt genomes. After data assembling and contigs joining, the complete mitochondrial genome sequence of G. hirsutum was obtained. The completed G.hirsutum mt genome is 621,884 bp in length, and contained 68 genes, including 35 protein genes, four rRNA genes and 29 tRNA genes. Five gene clusters are found conserved in all plant mt genomes; one and four clusters are specifically conserved in monocots and dicots, respectively. Homologous sequences are distributed along the plant mt genomes and species closely related share the most homologous sequences. For species that have both mt and chloroplast genome sequences available, we checked the location of cp-like migration and found several fragments closely linked with mitochondrial genes.ConclusionThe G. hirsutum mt genome possesses most of the common characters of higher plant mt genomes. The existence of syntenic gene clusters, as well as the conservation of some intergenic sequences and genic content among the plant mt genomes suggest that evolution of mt genomes is consistent with plant taxonomy but independent among different species.

Genome-scale rates of evolutionary change in bacteria.

Project description:Estimating the rates at which bacterial genomes evolve is critical to understanding major evolutionary and ecological processes such as disease emergence, long-term host-pathogen associations and short-term transmission patterns. The surge in bacterial genomic data sets provides a new opportunity to estimate these rates and reveal the factors that shape bacterial evolutionary dynamics. For many organisms estimates of evolutionary rate display an inverse association with the time-scale over which the data are sampled. However, this relationship remains unexplored in bacteria due to the difficulty in estimating genome-wide evolutionary rates, which are impacted by the extent of temporal structure in the data and the prevalence of recombination. We collected 36 whole genome sequence data sets from 16 species of bacterial pathogens to systematically estimate and compare their evolutionary rates and assess the extent of temporal structure in the absence of recombination. The majority (28/36) of data sets possessed sufficient clock-like structure to robustly estimate evolutionary rates. However, in some species reliable estimates were not possible even with 'ancient DNA' data sampled over many centuries, suggesting that they evolve very slowly or that they display extensive rate variation among lineages. The robustly estimated evolutionary rates spanned several orders of magnitude, from approximately 10-5 to 10-8 nucleotide substitutions per site year-1. This variation was negatively associated with sampling time, with this relationship best described by an exponential decay curve. To avoid potential estimation biases, such time-dependency should be considered when inferring evolutionary time-scales in bacteria.

Conserved novel ORFs in the mitochondrial genome of the ctenophore Beroe forskalii.

Project description:To date, five ctenophore species' mitochondrial genomes have been sequenced, and each contains open reading frames (ORFs) that if translated have no identifiable orthologs. ORFs with no identifiable orthologs are called unidentified reading frames (URFs). If truly protein-coding, ctenophore mitochondrial URFs represent a little understood path in early-diverging metazoan mitochondrial evolution and metabolism. We sequenced and annotated the mitochondrial genomes of three individuals of the beroid ctenophore Beroe forskalii and found that in addition to sharing the same canonical mitochondrial genes as other ctenophores, the B. forskalii mitochondrial genome contains two URFs. These URFs are conserved among the three individuals but not found in other sequenced species. We developed computational tools called pauvre and cuttlery to determine the likelihood that URFs are protein coding. There is evidence that the two URFs are under negative selection, and a novel Bayesian hypothesis test of trinucleotide frequency shows that the URFs are more similar to known coding genes than noncoding intergenic sequence. Protein structure and function prediction of all ctenophore URFs suggests that they all code for transmembrane transport proteins. These findings, along with the presence of URFs in other sequenced ctenophore mitochondrial genomes, suggest that ctenophores may have uncharacterized transmembrane proteins present in their mitochondria.

The complete sequence of the zebrafish (Danio rerio) mitochondrial genome and evolutionary patterns in vertebrate mitochondrial DNA.

Project description:We describe the complete sequence of the 16,596-nucleotide mitochondrial genome of the zebrafish (Danio rerio); contained are 13 protein genes, 22 tRNAs, 2 rRNAs, and a noncoding control region. Codon usage in protein genes is generally biased toward the available tRNA species but also reflects strand-specific nucleotide frequencies. For 19 of the 20 amino acids, the most frequently used codon ends in either A or C, with A preferred over C for fourfold degenerate codons (the lone exception was AUG: methionine). We show that rates of sequence evolution vary nearly as much within vertebrate classes as between them, yet nucleotide and amino acid composition show directional evolutionary trends, including marked differences between mammals and all other taxa. Birds showed similar compositional characteristics to the other nonmammalian taxa, indicating that the evolutionary trend in mammals is not solely due to metabolic rate and thermoregulatory factors. Complete mitochondrial genomes provide a large character base for phylogenetic analysis and may provide for robust estimates of phylogeny. Phylogenetic analysis of zebrafish and 35 other taxa based on all protein-coding genes produced trees largely, but not completely, consistent with conventional views of vertebrate evolution. It appears that even with such a large number of nucleotide characters (11,592), limited taxon sampling can lead to problems associated with extensive evolution on long phyletic branches.

Extreme mitochondrial evolution in the ctenophore Mnemiopsis leidyi: Insight from mtDNA and the nuclear genome.

Project description:Recent advances in sequencing technology have led to a rapid accumulation of mitochondrial DNA (mtDNA) sequences, which now represent the wide spectrum of animal diversity. However, one animal phylum--Ctenophora--has, to date, remained completely unsampled. Ctenophores, a small group of marine animals, are of interest due to their unusual biology, controversial phylogenetic position, and devastating impact as invasive species. Using data from the Mnemiopsis leidyi genome sequencing project, we Polymerase Chain Reaction (PCR) amplified and analyzed its complete mitochondrial (mt-) genome. At just over 10 kb, the mt-genome of M. leidyi is the smallest animal mtDNA ever reported and is among the most derived. It has lost at least 25 genes, including atp6 and all tRNA genes. We show that atp6 has been relocated to the nuclear genome and has acquired introns and a mitochondrial targeting presequence, while tRNA genes have been genuinely lost, along with nuclear-encoded mt-aminoacyl tRNA synthetases. The mt-genome of M. leidyi also displays extremely high rates of sequence evolution, which likely led to the degeneration of both protein and rRNA genes. In particular, encoded rRNA molecules possess little similarity with their homologs in other organisms and have highly reduced secondary structures. At the same time, nuclear encoded mt-ribosomal proteins have undergone expansions, likely to compensate for the reductions in mt-rRNA. The unusual features identified in M. leidyi mtDNA make this organism an interesting system for the study of various aspects of mitochondrial biology, particularly protein and tRNA import and mt-ribosome structures, and add to its value as an emerging model species. Furthermore, the fast-evolving M. leidyi mtDNA should be a convenient molecular marker for species- and population-level studies.

Evolutionary rates are correlated between cockroach symbionts and mitochondrial genomes.

Project description:Bacterial endosymbionts evolve under strong host-driven selection. Factors influencing host evolution might affect symbionts in similar ways, potentially leading to correlations between the molecular evolutionary rates of hosts and symbionts. Although there is evidence of rate correlations between mitochondrial and nuclear genes, similar investigations of hosts and symbionts are lacking. Here, we demonstrate a correlation in molecular rates between the genomes of an endosymbiont (Blattabacterium cuenoti) and the mitochondrial genomes of their hosts (cockroaches). We used partial genome data for multiple strains of B. cuenoti to compare phylogenetic relationships and evolutionary rates for 55 cockroach/symbiont pairs. The phylogenies inferred for B. cuenoti and the mitochondrial genomes of their hosts were largely congruent, as expected from their identical maternal and cytoplasmic mode of inheritance. We found a correlation between evolutionary rates of the two genomes, based on comparisons of root-to-tip distances and on comparisons of the branch lengths of phylogenetically independent species pairs. Our results underscore the profound effects that long-term symbiosis can have on the biology of each symbiotic partner.

Investment in rapid growth shapes the evolutionary rates of essential proteins.

Project description:Proteins evolve at very different rates and, most notably, at rates inversely proportional to the level at which they are produced. The relative frequency of highly expressed proteins in the proteome, and thus their impact on the cell budget, increases steeply with growth rate. The maximal growth rate is a key life-history trait reflecting trade-offs between rapid growth and other fitness components. We show that the maximal growth rate is weakly affected by genetic drift. The negative correlation between protein expression levels and evolutionary rate and the positive correlation between expression levels of highly expressed proteins and growth rates, suggest that investment in growth affects the evolutionary rate of proteins, especially the highly expressed ones. Accordingly, analysis of 61 families of orthologs in 74 proteobacteria shows that differences in evolutionary rates between lowly and highly expressed proteins depend on maximal growth rates. Analyses of complexes with key roles in bacterial growth and strikingly different expression levels, the ribosome and the replisome, confirm these patterns and suggest that the growth-related sequence conservation is associated with protein synthesis. Maximal growth rates also shape protein evolution in the other bacterial clades. Long-branch attractions associated with this effect might explain why clades with persistent history of slow growth are attracted to the root when the tree of prokaryotes is inferred using highly, but not lowly, expressed proteins. These results indicate that reconstruction of deep phylogenies can be strongly affected by maximal growth rates, and highlight the importance of life-history traits and their physiological consequences for protein evolution.
