Interrogating Global Chromatin Interaction Network by High-Throughput Chromosome Conformation Capture (Hi-C) in Plants

Methods Mol Biol. 2022:2484:55-67. doi: 10.1007/978-1-0716-2253-7_5.

Abstract

High-throughput chromosome conformation capture (Hi-C) enables the global quantification of chromatin interaction frequency in eukaryotic nuclei. This method is based on in situ Hi-C, in which chromatin is cross-linked with formaldehyde, then digested with restriction enzyme. Biotin-labeled nucleotide is incorporated before the spatially adjacent DNA ends are ligated, making it possible to enrich specifically the chimeric ligation products for deep sequencing. In this chapter, we describe a modified in situ Hi-C protocol for the global chromatin interaction analysis in plants.
