Genes required for <i>M. xanthus</i> fruiting body development.

1Codon bias was determined using the software available at the Computational Microbiology Laboratory http://www.cmbl.uga.edu/software.html. The larger the number the greater the deviation from normal M. xanthus codon usage. Genes with no entries have a codon bias consistent with other M. xanthus genes. 2tBLASTn algorithm was used to identify the four most closely related homologs. Each gene was classified as δ Proteobacteria if at least one of the four top homologs belongs to an organism in that group. Gene was classified as unique based on a 1e−10 cutoff. Gene was classified as ‘other’ if the closest four homologs belonged to another phylogenetic group. 3Code refers to the classification category. Proteins known to be involved in signal production or sensory transduction are denoted with an ‘S’. The remaining genes were examined for a putative enzymatic function in the annotation, which is indicated by an ‘E’
