Satellite DNA (satDNA) is a non-coding component of eukaryotic genomes, located mainly
in heterochromatic regions. Relevance of satDNA began to emerge with accumulating
evidence of its potential yet hardly comprehensible role that it can play in the genome of
many organisms. We isolated the first satDNA of the codling moth (Cydia pomonella,
Tortricidae, Lepidoptera), a species with holokinetic chromosomes and a single large
heterochromatic element, the W chromosome in females. The satDNA, called CpSAT-1, is …

Satellite DNA represents one of the major components of repetitive genome components.
Recent research is bringing more and more evidence about importance of this type of DNA,
which can play both structural and functional roles in eukaryotic genomes. In this study, we
described newly discovered satellite DNA in Cydia pomonella, CpSAT-1. Although this
satDNA can be found in all chromosomes, it is surprisingly underrepresented on the W
chromosome, the only heterochromatin block in Cydia pomonella genome. The CpSAT-1 is …
