Genome-wide mapping and distribution of 4acC in Arabidopsis. a Distributions (expressed as percentages) of 4acC peaks found among intergenic regions, promoters (within 1 kb upstream of the TSS), and gene bodies. Gene bodies were further divided into 5′ and 3′ UTRs, exons (excluding 5′ and 3′ UTRs), and introns. The p values were calculated by Fisher’s exact test (p < 2.2 × 10−16). b Distributions of 4acC modifications in different gene categories. The left panel shows the numbers and percentages of 4acC-modified genes in different gene categories. The right panel shows the distributions (as percentages) among different gene categories for the 4acC-acetylated genes. The asterisks in the pie chart indicate significant differences between the observed versus expected distributions of 4acC peaks (Fisher’s exact test, p < 10−5). miRNA, microRNA; tRNA, transfer RNA; snRNA, small nuclear RNA; snoRNA, small nucleolar RNA; TE, transposable element gene. c Number of protein-coding genes possessing 1, 2, or > 2 4acC peaks in their gene bodies. d 4acC profiles in gene regions. The 1 kb upstream and downstream flanking coding regions were aligned for all genes. TSS, transcription start site; TES, transcription end site. e Representative profiles of 4acC-IP and input in the region of chr1:6,122,935-6,135,584
