(Submitter supplied) DNA replication programs have been studied extensively in yeast and animal systems, where they have been shown to correlate with gene expression and certain epigenetic modifications. Despite the conservation of core DNA replication proteins, little is known about replication programs in plants. We used flow cytometry and tiling microarrays to profile DNA replication of Arabidopsis thaliana chromosome 4 (chr4) during early, mid, and late S phase. more...

(Submitter supplied) Ecotype-specific differences in genome methylation were assayed in Arabidopsis Col and Ler variations using genomic tiling microarrays. Comparative genome hybridization was also performed so that the contribution of ecotype-specific amplifications and deletions could be estimated and integrated into the analysis of differential DNA methylation. Keywords: methylation analysis and comparative genome hybridization

(Submitter supplied) The entire TIGR4 Arabidopsis thaliana ec. Col chromosome 4 assembly was used to design a genomic tiling microarray. This ~18.6 Mb sequence represented on the microarray starts downstream of the nucleolar organizing region (NOR) comprising the 5’ terminus of the chromosome. Notably, it contains several megabases of pericentromeric heterochromatin. In the microarray design, annotation was intentionally ignored, thus ensuring that repeated and unique sequences were equally represented. more...
