Abstract

We have stably transformed both Haloarcula vallismortis and Haloarcula hispanica with the halobacterium-Escherichia coli shuttle vectors pWL102 (based on the Haloferax volcanii pHV2 replicon) and pUBP2 (based on the Halobacterium halobium pHH1 replicon). Haloferax volcanii, Halobacterium halobium, and Haloarcula vailismortis are equally distant from one another and span the phylogenetic depth of the halophilic Archaea; thus, these vectors may be generally useful for the halophiles. Both Haloarcula vallismortis and Haloarcula hispanica exhibit previously unreported complex life cycles and are therefore significant as genetically approachable models of cellular differentiation within the Archaea.
