چکیده
Of Roman roads, train yards and inspectors: recent discoveries in RNA research RNA is a crucial biological molecule that is seldom mentioned in detail in textbooks. In the first article in a series, Russ Hodge describes some exciting recent research on RNA.

Vertebrate-type intron-rich genes in the marine annelid Platynereis dumerilii.
Previous genome comparisons have suggested that one important trend in vertebrate evolution has been a sharp rise in intron abundance. By using genomic data and expressed sequence tags from the marine annelid Platynereis dumerilii, we provide direct evidence that about two-thirds of human introns predate the bilaterian radiation but were lost from insect and nematode genomes to a large extent. ...
متن کاملMetazoan Evolution: Some Animals Are More Equal than Others
Comparison of newly available sequence data facilitates reconstruction of the gene inventory of the Urbilateria, the last common ancestor of flies, nematodes and humans. The most surprising outcome is that human genes seem to be closer to the bilaterian roots than previously assumed.

متن کاملConserved Sensory-Neurosecretory Cell Types in Annelid and Fish Forebrain: Insights into Hypothalamus Evolution
Neurosecretory control centers form part of the forebrain in many animal phyla, including vertebrates, insects, and annelids. The evolutionary origin of these centers is largely unknown. To identify conserved, and thus phylogenetically ancient, components of neurosecretory brain centers, we characterize and compare neurons that express the prohormone vasotocin (vasopressin/oxytocin)-neurophysin...

The structure, robustness, and dynamics of ocean plankton ecosystems remain poorly understood due to sampling, analysis, and computational limitations. The Tara Oceans consortium organizes expeditions to help fill this gap at the global level.
