Variations in the copy number of rrn operons (encoding the ribosomal RNAs)
in Bacteria and Archae, is one of the topics being considered in an
article that I am writing. I have accumulated a number of examples from
the literature documenting the variation from 1 to 10 copies, and would
like to make the list as comprehensive as possible. Frequently,
determination of rrn copy number is a sidelight of a study, and so not
accessible through title or keyword searches. If you know of any studies
where rrn copy number was determined, I would certainly appreciate you
sending the name of the organism, the copy number and a reference. Kindly
address replies to tschmidt at msu.edu. Thanks.
