Abstract:

Chromatin immunoprecipitation followed by sequencing(ChIP-seq)is an important method to study the interaction between DNA and target proteins,it has been widely used to study transcription factor and the functions and distributions of post-translation histone modification. In recent years,researchers have been optimizing the key steps of this method,including cell separation,chromatin fragmentation,immunoprecipitation and sequencing library construction,allowing the ChIP-seq suitable for the analysis of small amount of cells. In cleavage under targets and release using nucleus(CUT&RUN)and cleavage under targets and tagmentation(CUT&Tag),the enzyme is “targeted” to the target protein through specific antibodies,and the chromatin near the target protein is digested by MNase or Tn5 transposase,which simplifies the operation process. The paper provided an overview of the principle behind ChIP-seq and its data analysis methods,compared the ChIP-based optimization methods and derived methods,and summarized the studies of transcription factors and histone modification in the regulation of biological clock,hormone signal transduction,signal transduction pathway and stress response in the process of plant growth and development,as well as the application of ChIP-seq technique.

Key words: chromatin immunoprecipitation, transcription factors, histone modification, data analysis
