Genome-wide in silico mapping of scaffold/matrix attachment regions in Arabidopsis suggests correlation of intragenic scaffold/matrix attachment regions with gene expression.
We carried out a genome-wide prediction of scaffold/matrix attachment regions (S/MARs) in Arabidopsis. Results indicate no uneven distribution on the chromosomal level but a clear underrepresentation of S/MARs inside genes. In cases where S/MARs were predicted within genes, these intragenic S/MARs were preferentially located within the 5'-half, most prominently within introns 1 and 2. Using Ara...
متن کاملHuman matrix attachment regions insulate transgene expression from chromosomal position effects in Drosophila melanogaster.
Germ line transformation of white- Drosophila embryos with P-element vectors containing white expression cassettes results in flies with different eye color phenotypes due to position effects at the sites of transgene insertion. These position effects can be cured by specific DNA elements, such as the Drosophila scs and scs' elements, that have insulator activity in vivo. We have used this syst...
متن کاملGenome-wide deficiency mapping of the regions responsible for temporal canalization of the developmental processes of Drosophila melanogaster.
Developmental processes of organisms are programmed to proceed in a finely regulated manner and finish within a certain period of time depending on the ambient environmental conditions. Therefore, variation in the developmental period under controlled genetic and environmental conditions indicates innate instability of the developmental process. In this study, we aimed to determine whether a mo...
متن کاملMolecular Evolution in Nonrecombining Regions of the Drosophila melanogaster Genome
We study the evolutionary effects of reduced recombination on the Drosophila melanogaster genome, analyzing more than 200 new genes that lack crossing-over and employing a novel orthology search among species of the melanogaster subgroup. These genes are located in the heterochromatin of chromosomes other than the dot (fourth) chromosome. Noncrossover regions of the genome all exhibited an elev...
متن کاملGenome-wide analysis of Sox genes in Drosophila melanogaster
Genes of the Sox family encode evolutionarily conserved HMG box containing transcription factors, which play key roles in various events of cell determination/differentiation during development. The total number of Sox genes in Drosophila melanogaster was estimated to be eight, after classical molecular cloning approaches and exhaustive screening of the complete Drosophila genome. Here we repor...
