Fig. 6: Most essential genes contain transposon-tolerant coding segments.

a Most essential genes tolerate transposon insertions in at least one coding segment. Each segment constitutes one-tenth of the coding region, and a segment is considered tolerant to transposon insertions only when this is true in at least nine strains. b Number of monomorphic essential genes that tolerate transposons in each coding segment. c Number of monomorphic nonessential genes that tolerate transposons in each coding segment. d Examples of genes that are essential only in the N-terminus (first column), only in the C-terminus (second column), only in the central part (third column), and in multiple discontinuous parts (fourth column). Horizontal bars mark gene locations, with gene names provided below the bars and white arrows indicating transcriptional directions. Source data are provided as a Source Data file.
