Abstract
Here we report a high-quality draft genome sequence of the domestic dog (Canis familiaris), together with a dense map of single nucleotide polymorphisms (SNPs) across breeds. The dog is of particular interest because it provides important evolutionary information and because existing breeds show great phenotypic diversity for morphological, physiological and behavioural traits. We use sequence comparison with the primate and rodent lineages to shed light on the structure and evolution of genomes and genes. Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near a small subset of genes with important roles in development. Analysis of SNPs reveals long-range haplotypes across the entire dog genome, and defines the nature of genetic diversity within and across breeds. The current SNP map now makes it possible for genome-wide association studies to identify genes responsible for diseases and traits, with important consequences for human and companion animal health.

Abstract
The anticipated completion of two of the most biomedically relevant genomes, mouse and human, within the next three years provides an unparalleled opportunity for the large-scale exploration of genome evolution. Targeted sequencing of genomic regions in a panel of primate species and comparison to reference genomes will provide critical insight into the nature of single-base pair variation, mechanisms of chromosomal rearrangement, patterns of selection, and species adaptation. Although not recognized as model "genetic organisms" because of their longevity and low fecundity, 30 of the approximately 300 primate species are targets of biomedical research. The existence of a human reference sequence and genomic primate BAC libraries greatly facilitates the recovery of genes/genomic regions of high biological interest because of an estimated maximum neutral nucleotide sequence divergence of 25%. Primate species, therefore, may be regarded as the ideal model "genomic organisms". Based on existing BAC library resources, we propose the construction of a panel of primate BAC libraries from phylogenetic anchor species for the purpose of comparative medicine as well as studies of genome evolution.

Abstract
Vegetative cell walls and spore walls of seven Streptomyces species representing four types of spore morphology were qualitatively analysed for their components. Amino acid and carbohydrate components (glucose, glucosamine, muramic acid, diaminopimelic acid, glutamic acid, glycine, alanine, arginine, threonine, valine, leucine, and aspartic acid) in both types of walls were identical in all species. Aspartic acid was a major component in spore walls, but a minor component in vegetative cell walls. Although organic phosphate was present in both vegetative- and spore-wall hydrolysates, the other components of teichoic acid were not found nor was teichoic acid extracted from the isolated walls by cold trichloroacetic acid. A portion of the vegetative cell wall was rendered soluble with lysozyme and separated by paper electrophoresis into two fractions detected with ninhydrin. The lysozyme-resistant portion of the vegetative cell wall showed the same major and minor components as the spore walls, which are also lysozyme resistant.
