Distributions of the (A) total gene length, (B) total length of exons, (C) total length of introns, (D) number of transcripts, (E) number of exons, and (F) percentage of GC content in essential and viable genes. Here, EN and VN refer to essential and viable genes in the non–culled dataset. Ex and Vx define essential and viable genes in the culled dataset where all coded proteins share sequence similarity less than x0%. In this box plot, the top and bottom of the box denote the upper and lower quartiles; the line inside the box denotes the median; and individual points denote the outliers. Top 5% essential and viable genes with longest gene length (A) and longest introns (F) were excluded from the datasets to make plots more readable.
