Chromatin accessibility in D. discoideium (AX2) in different developmental stages

The goal of ATAC-seq is to identify the open chromatin regions in the wild-type D.discoideum at different developmental stages (vegetative, streaming, mound and fruiting bodyies). Two biological replicates were assigned for each group and in total 8 groups were prepared for ATAC-seq libraries. We mapped about 10 million reads per sample to D. discoideum with bowtie2 workflow. Open chromatin regions were deducted by ChIPseeker with corrected p < 0.05. Our results showed D. discoideum have dispartate chromatin accessibility regions throughout the genome. Nuclei from vegetative, streaming, mound and fruiting body stages were extacted and transposed, and cDNA libraries were generated for deep sequencing, in duplicate, using Nextseq500
