Fig. 4

Gene expression variation throughout time and between body parts. a Main variation of transcript expression between the two embryonic body parts (head and trunk) at three different developmental stages (8 dpf, 14 dpf and 20 dpf) illustrated by a PCA. The axes represent the percentage of variance explained by PC1 (x-axis) and PC2 (y-axis). b Principal components of the transcript expression PCA shown in panel (a). c Distribution of median transcript expression within each sample type. d Distribution of median transcript expression within each sample type after outlier removal. Orange: head, blue: trunk
