Fig. 2.

PCA of RNA-Seq data and developmental timing of apical and basal buds. (A) T1, T3 and T5 samples are shown in the PCA with red, green and blue shadings, respectively. The variation explained by the first two PCs is shown in the axes. The asterisk marks an outlier of apical buds, while the grey arrows indicate a likely developmental line followed by the buds’ transcriptomes. (B) Positions of the different sampling timepoints of both apical and basal buds with respect to development according to the first PC
