A molecular clock based on the expansion of gene families.
There is evidence to suggest that eukaryotic genomes are subject to frequent insertions and deletions of non-coding DNA. This may lead to a gradual increase or decrease in genome size, or to a dynamic equilibrium in which the overall size remains constant. We argue, however, that there is a bias favouring an accumulation of non-coding DNA in the proximity of genes. Such bias causes a progressiv...
متن کاملMassive Expansion of Ubiquitination-Related Gene Families within the Chlamydiae
Gene loss, gain, and transfer play an important role in shaping the genomes of all organisms; however, the interplay of these processes in isolated populations, such as in obligate intracellular bacteria, is less understood. Despite a general trend towards genome reduction in these microbes, our phylogenomic analysis of the phylum Chlamydiae revealed that within the family Parachlamydiaceae, ge...

Introduction Fish models have become very popular during the past decade (see Fig. 1 for phylogenetic relationships). Recently established models for genomic studies (the Japanese and freshwater pufferfish, Fugu rubripes and Tetraodon nigroviridis, respectively) and for developmental biology (the zebrafish, Danio rerio) are now the focus of interest of many biologists, although ‘old’ models are...
متن کاملZebra Fish Lacking Adaptive Immunity Acquire an Antiviral Alert State Characterized by Upregulated Gene Expression of Apoptosis, Multigene Families, and Interferon-Related Genes
To investigate fish innate immunity, we have conducted organ and cell immune-related transcriptomic as well as immunohistologic analysis in mutant zebra fish (Danio rerio) lacking adaptive immunity (rag1-/-) at different developmental stages (egg, larvae, and adult), before and after infection with spring viremia carp virus (SVCV). The results revealed that, compared to immunocompetent zebra fi...
