a Scatter plot of correlations between snoRNA log fold changes with YR-initiation log fold changes (left), and with YC-initiation log fold changes (right) across six developmental stages among 94 dual-initiation snoRNA host genes. Each point corresponds to one stage-gene pair of YR-dominant transcripts (blue), YC-dominant transcripts (red) and the rest (black). b Bar plot of CAGE expression levels (tpm) of YR (blue) and YC (red) components of initiation at the nop56 gene. Expression levels of snoRNA (dark green) were calculated from small RNA-seq data in reads per million. c Box plot of TPM expression levels of YR-initiation (blue), YC-initiation (red), and total (black) of YR-dominant and YC-dominant snoRNA host genes selected for comparable total expression level are shown. The number of YR-dominant and YC-dominant snoRNA host genes are denoted by “N”. d Box plot of expression levels of corresponding snoRNAs (green) from YR-dominant and YC-dominant host genes shown in d. Developmental stages are fertilized egg, 30% epiboly and prim 5 stages (top to bottom) are depicted on the left. Boxplots show the 5th, 25th, 50th, 75th, and 95th percentiles where center line is the median.
