Database for Plant Transcription Factor Binding Sites.

Abstract

Reconstruction of gene regulatory networks is a very important but difficult issue in plant sciences. Recently, numerous high-throughput techniques, such as chromatin immunoprecipitation sequencing (ChIP-seq) and DNA affinity purification sequencing (DAP-seq), have been developed to identify the genomic binding landscapes of regulatory factors. To understand the relationships among transcription factors (TFs) and their corresponding binding sites on target genes is usually the first step for elucidating gene regulatory mechanisms. Therefore, a good database for plant TFs and transcription factor binding sites (TFBSs) will be useful for starting a series of complex experiments. In this chapter, PlantPAN (version 3.0) is utilized as an example to explain how bioinformatics systems advance research on gene regulation.
