Extremely high copy numbers and polymorphisms of the rDNA operon estimated from single cell analysis of oligotrich and peritrich ciliates.

Protist - 1 May 2013

Gong Jun, Dong Jun, Liu Xihan, Massana Ramon

Abstract excerpt

The copy number and sequence variation of the ribosomal DNA (rDNA) operon are of functional significance in evolution and ecology of organisms. However, the relationship between copy number and sequence variation of rDNA in protists has been rarely studied. Here we quantified rDNA copy numbers of oligotrich and peritrich ciliate species using single-cell quantitative PCR. We also examined the rDNA sequence...
