From: Post-genomics of the model haloarchaeon Halobacterium sp. NRC-1
"Bacterial" gene content in the Halobacterium sp. NRC-1 replicon pNRC200. A. Average bacterial character is plotted in a 40 ORF window (innermost plot in blue). Individual genes closely related to bacteria in Blast analysis are shown with blue dots while those identified through COG analysis are shown as red dots. IS elements are indicated by lines on the outermost circle. B. Quartet puzzling maximum-likelihood phylogenetic tree of ArgS sequences from archaea and three classes of bacteria. A probable LGT of an argS gene from a bacterium to Halobacterium (Hbt. NRC-1) is apparent. Two other haloarchaea (Haloferax volcanii: H. vo; Haloarcula marismortui: H. ma) contain archaeal-type ArgS-coding genes.
