rRNA genes of Naegleria gruberi are carried exclusively on a 14-kilobase-pair plasmid.

Rockefeller University, New York, New York 10021-6399.

ABSTRACT

An extrachromosomal DNA was discovered in Naegleria gruberi. The 3,000 to 5,000 copies per cell of this 14-kilobase-pair circular plasmid carry all the 18S, 28S, and 5.8S rRNA genes. The presence of the ribosomal DNA of an organism exclusively on a circular extrachromosomal element is without precedent, and Naegleria is only the third eucaryotic genus in which a nuclear plasmid DNA has been found.
