TL;DR: These sequences provide a starting point for a new era in the functional analysis of a key model organism and show that the molecular nature of functional variants and their position relative to genes vary according to the effect size of the locus.
Abstract: We report genome sequences of 17 inbred strains of laboratory mice and identify almost ten times more variants than previously known. We use these genomes to explore the phylogenetic history of the laboratory mouse and to examine the functional consequences of allele-specific variation on transcript abundance, revealing that at least 12% of transcripts show a significant tissue-specific expression bias. By identifying candidate functional variants at 718 quantitative trait loci we show that the molecular nature of functional variants and their position relative to genes vary according to the effect size of the locus. These sequences provide a starting point for a new era in the functional analysis of a key model organism.

TL;DR: Comparisons of the predicted amino acid sequences of VZV proteins with those available for HSV-1 proteins generally suggest evolution from an ancestral genome, and allow the functions of several VzV genes to be deduced, although limited regions where the genomes differ in functional organization were also identified.
Abstract: Summary The entire DNA sequence of varicella-zoster virus (VZV) was determined using the M13-dideoxynucleotide technology. The genome is variable in size, but the sequence which was obtained comprises 124884 bp. Analysis of the sequence indicated that the genome contains 70 genes distributed about equally between the two DNA strands. The genes are organized compactly, but regions of overlap between protein-coding regions are not extensive. Many of the genes are arranged in 3′-coterminal families, and at least one is spliced. The discerned organization of VZV genes and that deduced for herpes simplex virus type 1 (HSV-1) from published transcript mapping data indicate that these two members of the Alphaherpesvirinae are very similar in gene layout. Comparisons of the predicted amino acid sequences of VZV proteins with those available for HSV-1 proteins generally suggest evolution from an ancestral genome, and allow the functions of several VZV genes to be deduced, although limited regions where the genomes differ in functional organization were also identified.

TL;DR: An overview of the project and the resources it is generating and the application of ENCODE data to interpret the human genome are provided.
Abstract: The mission of the Encyclopedia of DNA Elements (ENCODE) Project is to enable the scientific and medical communities to interpret the human genome sequence and apply it to understand human biology and improve health. The ENCODE Consortium is integrating multiple technologies and approaches in a collective effort to discover and define the functional elements encoded in the human genome, including genes, transcripts, and transcriptional regulatory regions, together with their attendant chromatin states and DNA methylation patterns. In the process, standards to ensure high-quality data have been implemented, and novel algorithms have been developed to facilitate analysis. Data and derived results are made available through a freely accessible database. Here we provide an overview of the project and the resources it is generating and illustrate the application of ENCODE data to interpret the human genome.

TL;DR: The Fugu rubripes genome has been sequenced to over 95% coverage, and more than 80% of the assembly is in multigene-sized scaffolds as discussed by the authors.
Abstract: The compact genome of Fugu rubripes has been sequenced to over 95% coverage, and more than 80% of the assembly is in multigene-sized scaffolds. In this 365-megabase vertebrate genome, repetitive DNA accounts for less than one-sixth of the sequence, and gene loci occupy about one-third of the genome. As with the human genome, gene loci are not evenly distributed, but are clustered into sparse and dense regions. Some “giant” genes were observed that had average coding sequence sizes but were spread over genomic lengths significantly larger than those of their human orthologs. Although three-quarters of predicted human proteins have a strong match toFugu, approximately a quarter of the human proteins had highly diverged from or had no pufferfish homologs, highlighting the extent of protein evolution in the 450 million years since teleosts and mammals diverged. Conserved linkages between Fugu and human genes indicate the preservation of chromosomal segments from the common vertebrate ancestor, but with considerable scrambling of gene order.
