Gene activity is regulated via chromatin dynamics in eukaryotes. In plants, alterations of histone modifications are correlated with gene regulation for development, vernalization, and abiotic stress responses. Using ChIP, ChIP-on-chip, and ChIP-seq analyses, the direct binding regions of transcription factors and alterations of histone modifications can be identified on a genome-wide level. We have established reliable and reproducible ChIP and ChIP-on-chip methods that have been optimized for the Arabidopsis model system. These methods are not only useful for identifying the direct binding of transcription factors and chromatin status but also for scanning the regulatory network in Arabidopsis.
