Accumulating evidence for alternative gene orders demonstrates that vertebrate mitochondrial genomes are more evolutionarily dynamic than previously thought. Several lineages of parthenogenetic lizards contain large, tandem duplications that include rRNA, tRNA, and protein-coding genes, as well as the control region. Such duplications are hypothesized as intermediate stages in gene rearrangement, but the early stages of… [Read More]

Our analysis of the plague diagnostic phage L-413C genome sequence and structure reveals that L-413C is highly similar and collinear with enterobacteriophage P2, though important differences were found. Of special interest was the mosaic nature of the tail fiber protein H in L-413C, given the differentiating specificity of this phage for Yersinia pestis vs. Yersinia… [Read More]

The chicken genome draft sequence has provided a valuable resource for studies of an important agricultural and experimental model species and an important data set for comparative analysis. However, some of the most gene-rich segments are missing from chicken genome draft assemblies, limiting the analysis of a substantial number of genes and preventing a closer… [Read More]

Chloroplast genome organization, gene order, and content are highly conserved among land plants. We sequenced the chloroplast genome of Trachelium caeruleum L. (Campanulaceae), a member of an angiosperm family known for highly rearranged genomes. The total genome size is 162,321 bp, with an inverted repeat (IR) of 27,273 bp, large single-copy (LSC) region of 100,114… [Read More]

Growing concerns about global climate change and energy dependence have led to an increased effort to reduce carbon emissions. A considerable reduction could be achieved by using biofuels from lignocellulosic biomass instead of fossil fuels. One major bottleneck of biofuel production from lignocellulose is the availability of efficient and inexpensive biocatalysts (i.e. alcohol dehydrogenases, cellulases… [Read More]

Two genes encoding esterases EstA and EstB of Picrophilus torridus were identified by the means of genome analysis and were subsequently cloned in Escherichia coli. PTO 0988, which is encoding EstA, consists of 579 bp, whereas PTO 1141, encoding EstB, is composed of 696 bp, corresponding to 192 aa and 231 aa, respectively. Sequence comparison… [Read More]
