Arabidopsis seed germination is characterized by two translational shifts. (a) Principal component (PC) analysis of polysome occupancy (PO) changes (polysomal mRNA levels/total mRNA levels) during seed germination. The first two components (PC1 and PC2) explain 30 and 13% of the total variation, respectively. (b) The number of mRNAs with changed PO at the two translational shifts, at 6 h after the start of imbibition (HAI) the hydration translational shift (HTS) and 48 HAI, the germination translational shift (GTS). (c) Dynamics of genes underlying the two translational shifts. The levels of total (x‐axis) and polysomal (y‐axis) mRNAs following seed imbibition (dry seeds, 6, 26, 48 and 72 HAI) are plotted (black). Genes identified with increased (red dots) or decreased (green dots) polysome occupancy are indicated for both the HTS (upper panels) and the GTS (lower panels).
