Centrosome Biogenesis: Centrosomin Sizes Things Up!

Centrosomes are composed of a centriole pair surrounded by a proteinaceous matrix of pericentriolar material that contains protein complexes required for microtubule nucleation and anchoring. Recent work reveals an intriguing link between centrioles and pericentriolar material that is involved in modulating centrosome size.

Genesis and the Genome: Genomics Evidence for Human-Ape Common Ancestry and Ancestral Hominid Population Sizes

The relatively new and rapidly expanding field of comparative genomics provides a wealth of data useful for testing the hypothesis that humans and other forms of life share common ancestry. Numerous independent lines of genomics evidence strongly support the hypothesis that our species shares a common ancestor with other primates. Additional lines of evidence also indicate that our species has ...

Minimum sample sizes for population genomics: an empirical study from an Amazonian plant species.

High-throughput DNA sequencing facilitates the analysis of large portions of the genome in nonmodel organisms, ensuring high accuracy of population genetic parameters. However, empirical studies evaluating the appropriate sample size for these kinds of studies are still scarce. In this study, we use double-digest restriction-associated DNA sequencing (ddRADseq) to recover thousands of single nu...

Evolutionary genomics: Thermotoga heats up lateral gene transfer

Prokaryotes exchange genes on a regular basis, especially under highly selective conditions (such as in the presence of antibiotics). These DNA transfer events have been appreciated by biologists for some time now. Indeed, it was recognized early on that this process could have profound implications for the evolution of microbes and our ability to trace their history, yet most microbiologists m...
