Common evolutionary origin for the unstable virulence plasmid pMUM found in geographically diverse strains of Mycobacterium ulcerans

The 174-kb virulence plasmid pMUM001 in Mycobacterium ulcerans epidemic strain Agy99 harbors three very large and homologous genes that encode giant polyketide synthases (PKS) responsible for the synthesis of the lipid toxin mycolactone. Deeper investigati ...

A Morphogenetic Evolutionary System: Phylogenesis of the POEtic Circuit

Dario Floreano, Claudio Mattiussi, Daniel Roggen

This paper describes a new evolutionary mechanism developed specifically for cellular circuits. Called morphogenetic system, it is inspired by the mechanisms of gene expression and cell differentiation found in living organisms. It will be used as the phyl ...

A new evolutionary scenario for the Mycobacterium tuberculosis complex

Stewart Cole

The distribution of 20 variable regions resulting from insertion-deletion events in the genomes of the tubercle bacilli has been evaluated in a total of 100 strains of Mycobacterium tuberculosis, Mycobacterium africanum, Mycobacterium canettii, Mycobacteri ...

tbx20, a new vertebrate T-box gene expressed in the cranial motor neurons and developing cardiovascular structures in zebrafish

Andrew Charles Oates

The T-box genes constitute a family of transcriptional regulator genes that have been implicated in a variety of developmental processes ranging from the formation of germ layers to the regionalization of the central nervous system. In this report we descr ...

Learning and Evolution

Dario Floreano

In the last few years several researchers have resorted to artificial evolution (e.g. genetic algorithms) and learning techniques (e.g. neural networks) for studying the interaction between learning and evolution. These studies have been conducted for two ...

How co-evolution can enhance the adaptation power of artificial evolution: Implications for evolutionary robotics

Dario Floreano

Co-evolution (i.e. the evolution of two or more competing populations with coupled fitness) has several interesting features that may potentially enhance the power of adaptation of artificial evolution. In particular, as discussed by Dawkins and Krebs [2], ...

Characterization of two genes, glpQ and ugpQ, encoding glycerophosphoryl diester phosphodiesterases of Escherichia coli

Stewart Cole

The nucleotide sequences of the glpQ and ugpQ genes of Escherichia coli, which both encode glycerophosphoryl diester phosphodiesterases, were determined. The glpQ gene encodes a periplasmic enzyme of 333 amino acids, produced initially with a 25 residue lo ...
