Genome-wide identification of HexA binding sites in Pectobacterium carotovorum PCC27 using ChIP-seq


ABSTRACT: HexA is a global transcriptional regulator involved in quorum sensing and virulence regulation in Pectobacterium carotovorum PCC27. To identify genome-wide DNA binding sites of HexA, we performed chromatin immunoprecipitation followed by sequencing (ChIP-seq) using a FLAG-tagged HexA strain. Samples were collected at two different growth phases—mid-log and early stationary—to investigate condition-dependent differences in HexA binding profiles. A total of six samples (three biological replicates per condition) were sequenced on the Illumina NovaSeq 6000 platform using paired-end 101 bp reads. Peaks were called using MACS2, and downstream analysis was performed with ChIPseeker. This study provides insight into the dynamic regulation of HexA across bacterial growth stages.
