Reply to Santiago-Rodriguezet al.: WasluxSreally isolated from 25- to 40-million-year-old bacteria?

luxS in bacteria isolated from 25- to 40-million-year-old amber.

Interspecies bacterial communication is mediated by autoinducer-2, whose synthesis depends on luxS. Due to the apparent universality of luxS (present in more than 40 bacterial species), it may have an ancient origin; however, no direct evidence is currently available. We amplified luxS in bacteria isolated from 25- to 40-million-year-old amber. The phylogenies and molecular clocks of luxS and t...

Draft Genome Sequence of Staphylococcus succinus subsp. succinus Type Strain DSM 14617, Isolated from Plant and Soil Inclusions within 25- to 35-Million-Year-Old Dominican Amber

Staphylococcus succinus subsp. succinus type strain DSM 14617 was isolated from plant and soil inclusions within 25- to 35-million-year-old Dominican amber. The complete genome sequence of strain DSM 14617T includes a genome of 2.88 Mb (32.94% G+C content) without any plasmids.

Reply to Gratiy et al.

TO THE EDITOR: Gratiy et al. (2013) proposed two alternative explanations for the nonbalanced current source density (CSD) estimates in Riera et al. (2012). Their commentary was based on a particular interpretation of the role played by the Ampere-Maxwell Law in the genesis of the electric fields for macroscopic media. In this Reply, we will provide further information to stimulate the debate i...
