title: Chromatin charting: global mapping of epigenetic effects.
abstract: To tackle the question of how chromatin organization is involved in global regulation of genome-related processes such as transcription, we have recently created a collection of 277 transposon-tagged Arabidopsis lines comprised of a single insert with a common luciferase reporter cassette and a LacO repeat array for visual tracking of the tagged region via fluorescent protein fusion technology. Using this collection of plants, one can begin to map transgene position effects as well as global epigenetic control in response to developmental or externally applied cues. In this chapter, we will outline the approach and methods for deploying this novel resource for the study of global gene control, using Arabidopsis as a convenient model system.
