P) Comparison of the total levels of the different Sen1 variants at mRNAs, CUTs and the termination region of snoRNAs (i.e. a window of 200 nt downstream of the 3' end of the mature snoRNA, snoRNA-ter). Boxes in box-plots include all the values between the 25th and the 75th percentiles and the horizontal line indicates the median. The upper error bars indicate the distance between the largest value smaller than or equal to the upper limit of the box + 1.5 *IQR. The lower error bars indicate the distance between the lowest value greater than or equal to the lower limit of the box - 1.5 *IQR. Datasets for the different Sen1 versions were compared using a t-test (bilateral distributions, unpaired data). p-values≥ 0.05 are indicated as ns (not significant), one asterisk is used when 0.05>p-value≥0.01, two asterisks when 0.01>p-value≥0.001 and three asterisks for p-value <0.001.
