Box Plot from Scientific Research

In aerial parts of Arabidopsis seedlings, gene expression correlates with the number of GATC motifs within 500 bp downstream of the TSS. Expression values are depicted for various motif counts, with ‘4+’ representing four to nine motifs. A linear fit reveals a GATC motif effect size of 0.4 (P value = 5 x 10 -128), indicating the average expression increase for each added motif. Box plots display the median (center line), the IQR (box bounds), whiskers (minimum and maximum within 1.5 IQR) and outliers (points beyond whiskers); the number of genes per category is also indicated. P values were calculated using a two-sided t -statistic.
