... in chromosome copy number regulation. Polyploidy has many evolutionary advantages for haloarchaea, e.g. a high resistance to desiccation, survival over geological times, and the relaxation of cell cycle-specific replication control. A further advantage is the ability to grow in the absence of external phosphate...

...Jörg Soppa Several species of haloarchaea have been shown to be polyploid and thus this trait might be typical for and widespread in haloarchaea. In the present paper, nine different possible evolutionary advantages of polyploidy for haloarchaea are discussed, including low mutation rate, radiation...

... Euryarchaea are typically oligoploid or polyploidy and their genome copy numbers are tightly regulated in response to growth phase and/or growth rate. A theoretical consideration called ‘Muller's ratchet’ predicts that asexually reproducing polyploid species should not be able to exist. An escape from...
