The Genomicus web server (http://www.genomicus.biologie.ens.fr/genomicus) is a 
visualization tool allowing comparative genomics in four different phyla 
(Vertebrate, Fungi, Metazoan and Plants). It provides access to genomic 
information from extant species, as well as ancestral gene content and gene 
order for vertebrates and flowering plants. Here we present the new features 
available for vertebrate genome with a focus on new graphical tools. The 
interface to enter the database has been improved, two pairwise genome 
comparison tools are now available (KaryoView and MatrixView) and the multiple 
genome comparison tools (PhyloView and AlignView) propose three new kinds of 
representation and a more intuitive menu. These new developments have been 
implemented for Genomicus portal dedicated to vertebrates. This allows the 
analysis of 68 extant animal genomes, as well as 58 ancestral reconstructed 
genomes. The Genomicus server also provides access to ancestral gene orders, to 
facilitate evolutionary and comparative genomics studies, as well as 
computationally predicted regulatory interactions, thanks to the representation 
of conserved non-coding elements with their putative gene targets.
