Target analysis by integration of transcriptome and ChIP-seq data with BETA.

abstract：:In most organisms, one crossover (CO) event inhibits the chances of another nearby event. The term used to describe this phenomenon is 'CO interference'. Here, we describe a protocol for quickly generating large data sets that are amenable to CO interference analysis in the flowering plant, Arabidopsis thaliana. We em...
