Genetic Hyperviariability in Halobacterium Halobium

古细菌盐杆菌含有细胞内充满气体的囊泡，赋予细胞浮力。研究人员将利用含有气体囊泡基因的质粒，开发这种生物的克隆载体。正在进行与质粒稳定性有关的位点的研究，以确定导致一类部分真空和极不稳定的囊泡突变的机制。

The archaebacterium Halobacterium halobium contains intracellular gas-filled vesicles that confer buoyancy to the cell. Research will be carried out on the development of a cloning vector for this organism, using the plasmid which contains the genes for the gas vesicles. Studies of the loci involved with plasmid stability are being undertaken in order to determine the mechanism responsible for a class of vesicle mutants which are partially vac and extremely unstable.
