Whitaker, "Augmenting the genetic toolbox for Sulfolobus islandicus with a stringent positive selectable marker for agmatine prototrophy," Applied and Environmental Microbiology, vol.
Both plasmids were introduced into and restored uracil and uridine prototrophy of GR6 with frequencies of three transformants per [micro]g of plasmid DNA for pUC_pyrGAo and 50 transformants per [micro]g of plasmid DNA for ANEp2.
On the other hand, the phenomenon of reversion to prototrophy occurs as a consequence of new mutations at the site of the preexisting ones or near the mutated genes, which restore the gene's function and allow the cells to synthesise the required amino acid histidine (Mortelmans and Zeiger, 2000).
