Transcripts of centromeric satellite DNAs are known to play a role in heterochromatin formation as well as in establishment of the kinetochore. However, little is known about basic mechanisms of satellite DNA expression within constitutive heterochromatin and its regulation. Here we present comprehensive analysis of transcription of abundant centromeric(More)
In the red flour beetle Tribolium castaneum the major TCAST satellite DNA accounts for 35% of the genome and encompasses the pericentromeric regions of all chromosomes. Because of the presence of transcriptional regulatory elements and transcriptional activity in these sequences, TCAST satellite DNAs also have been proposed to be modulators of gene(More)
Tandemly repeated satellite DNAs are among most rapidly evolving sequences in eukaryotic genome, usually differing significantly among closely related species. By inducing changes in heterochromatin and/or centromere, satellite DNAs are expected to drive population and species divergence. However, despite high evolutionary dynamics, divergence of satellite(More)
Non-coding repetitive DNAs have been proposed to perform a gene regulatory role, however for tandemly repeated satellite DNA no such role was defined until now. Here we provide the first evidence for a role of satellite DNA in the modulation of gene expression under specific environmental conditions. The major satellite DNA TCAST1 in the beetle Tribolium(More)
In the legends for Fig 1 and S1 Fig, the name of the TCAST1 element subfamily Tcast2b is incorrect and should be replaced with Tcast1b. The correct legends are below.
