However, a correlation between gene sequence length and expression diversity, opposite to that observed for intergenic sequences, has also been reported, and to date there is no testable explanation for this observation.
Aberrant modification of histones associated with DNA repetitive sequences has also been reported.
Preference for particular non-A.T-rich sequences has also been reported [ 50, 51].
A preference for AT-rich sequences has also been reported for D. melanogaster ORC (MacAlpine et al., 2004), which additionally appears to localize predominantly at active promoters with open chromatin structure (MacAlpine et al., 2010), a feature of origins also observed in S. cerevisiae (Eaton et al., 2010).
These sequences have also been reported to be useful in the assessment of the treatment response [4, 14].
Weak palindromic consensus sequences have also been reported to be a common feature at the integration target sites of many retroviruses [9].
Smaller transgenes, only including Xist and flanking sequences, have also been reported to induce ectopic XCI in male cells, when present as multiple tandemly inserted transgenes [15], [16].
Although shared mitochondrial sequences have also been reported in white-headed gulls [5], in Darwin's finches [17], and possibly in crossbills [18], the present study reinforces earlier evidence that such cases are exceptional in both Nearctic and Neotropical locales despite the known existence of hybridization in birds, which involves around 10% of the world's species [19].
WSSV-like sequences have also been reported from the genome of P. monodon from Australia [ 12].
Differences between native and simulated sequences have also been reported in other studies [ 14].
