Sulfolobales

In taxonomy, the Sulfolobales are an order of the Thermoprotei.〔See the NCBI (webpage on Sulfolobales ). Data extracted from the (【引用サイトリンク】 title=NCBI taxonomy resources )
==DNA transfer==
Exposure of ''Sulfolobus solfataricus'' to the DNA damaging agents UV-irradiation, bleomycin or mitomycin C induces cellular aggregation. Other physical stressors, such as pH or temperature shift, do not induce aggregation, suggesting that induction of aggregation is caused specifically by DNA damage. Ajon et al. showed that UV-induced cellular aggregation mediates chromosomal marker exchange with high frequency. Recombination rates exceeded those of uninduced cultures by up to three orders of magnitude. Frols et al.〔 and Ajon et al.〔 hypothesized that the UV-inducible DNA transfer process and subsequent homologous recombinational repair represents an important mechanism to maintain chromosome integrity. This response may be a primitive form of sexual interaction, similar to the more well-studied bacterial transformation that is also associated with DNA transfer between cells leading to homologous recombinational repair of DNA damage.〔Bernstein H and Bernstein C (2013). Evolutionary Origin and Adaptive Function of Meiosis. In Meiosis: Bernstein C and Bernstein H, editors. ISBN 978-953-51-1197-9, InTech, http://www.intechopen.com/books/meiosis/evolutionary-origin-and-adaptive-function-of-meiosis〕 In another related species, ''Sulfolobus acidocaldarius'', UV-irradiation also increases the frequency of recombination due to genetic exchange.
