Chromatin immunoprecipitation (ChIP) provides a versatile tool to investigate the in vivo location of DNA-binding proteins on genomic DNA. ChIP approaches are gaining significance in plants, in cases when entire genome sequences are available (e.g., Arabidopsis), for which several high-density oligo arrays have been or are being developed. Nevertheless, plant ChIP and ChIP-chip still present some technical challenges. Here, we describe general methods for ChIP and ChIP-chip, which have been successfully applied to maize and Arabidopsis.

Methods to identify protein–DNA interactions include experimental and computational approaches, or combinations thereof (1). Experimental approaches involve investigating the formation of protein–DNA complexes for example by electrophoretic mobility shift assays (EMSA) or by exploring the specific DNA sequence recognized by a TF on a given fragment of DNA using chemical or nuclease footprinting techniques. These techniques, however,...
