Fig. 2: rDNA variation is stratified by habitat.
From: Varying strength of selection contributes to the intragenomic diversity of rRNA genes
a Distribution of the number of rDNA variants across different habitats from ref. 34 grouped by rDNA element. Significance test: two-sided Wilcoxon rank-sum test adjusted for multiple hypothesis testing using the Benjamini–Hochberg correction. For ETS+ITS, wild vs domesticated: W = 45,070, p = 0.004, location shift = −1, 95% confidence interval (CI) [−1,0]. For rRNA, wild vs domesticated: W = 26,653, p = 6 × 10−4, location shift = −1, 95% CI [−1, −6 × 10−5]; wild vs human body: W = 5038, p = 0.046, location shift = −6.2 × 10−6, 95% CI [−1, 0]. b Distribution of total rDNA copy numbers across the habitats. Significance test: two-sided Wilcoxon rank-sum test adjusted for multiple hypothesis testing using the Benjamini–Hochberg correction. For human body vs wild: W = 8534.5, p = 1.6 × 10−4, location shift = −30, 95% CI [−44,−16]; for human body vs domesticated: W = 20,162, p = 3.9 × 10−5, location shift = −32, 95% CI [−46,−18]; for human body vs unknown: W = 800.5, p = 0.004, location shift = −34, 95% CI [−54, −13]. For a and b, each dot is an isolate, the center line in the red box plot is the median, box limits are 25th and 75th percentiles, and the whiskers extend to ±1.5xIQR.
