Number of FAIRE reads in defense-related genes WRKY6 (A), WRKY29 (B), WRKY53 (C), FMO1 (D), and MLO3 (E) in unchallenged systemic leaves of Local mock and Local Psm plants. The variation in the height of the shading region indicates the sequence coverage levels in three independent biological replicates. Read depth was normalized based on total coverage assigned to the nuclear genome. The broken vertical line indicates the TSS. The numbers on the y axis give the distance from the TSS (in bp). −, upstream of the TSS; +, downstream of the TSS. The experiment was performed with six replicates of each sample (three for single-end and another three for paired-end sequencing). SE, single-end reads; PE, paired-end reads; Psm, Local Psm plants; mock, Local mock plants.
