Whole-genome microarrays: applications and technical issues.

Abstract

DNA microarrays have become a mainstream tool in experimental plant biology. The constant improvements in the technological platforms have enabled the development of the tiling DNA microarrays that cover the whole genome, which in turn catalyzed the wide variety of creative applications of such microarrays in the areas as diverse as global studies of genetic variation, DNA-binding proteins, DNA methylation, and chromatin and transcriptome dynamics. This chapter attempts to summarize such applications as well as discusses some technical and strategic issues that are particular to the use of tiling microarrays.
