Comments

At least two separate clusters of Bari1 repeats exist in the h39 region.

Bari1 elements are unstable in Charolles stock. Instability is persistent over 53 generations and appears to affect recurrent insertion sites.

rl undergoes polytenization in salivary gland chromosomes to a degree comparable to that of euchromatic genes, despite its deep heterochromatic location. Bari1 sequences located to the left are severely underrepresented and thus appear to be α-heterochromatin.

By comparing methylation by Ecol\dam methylase between euchromatic and heterochromatic genes it was determined that the heterochromatic state does not prevent methylase accessibility in vivo.

Bari1 is widespread in the genus Drosophila.

The distribution of transposable elements within heterochromatin indicates that they are major structural components of the heterochromatin.

The 1.7kb Bari1 element makes up a middle repetitive DNA family that shows many characteristics in common with transposable elements, though its mobility has not yet been demonstrated. Most copies are homogeneously clustered with a unique location close to the centromere of the second chromosome, and all copies have the same open reading frame.
