Figure 4. Images of the shoot apical meristem and the stem regions of the Arabidopsis plants.
(A) Longitudinal sections of the SAMs of the 4-week-old wild type (WT), AtU11/U12-31K knockdown mutant (amiR1-4), and complementation line expressing OsU11/U12-31K (amiR1-4/Os31K). Bar = 50 µm. (B) Longitudinal sections through the stems of 4-week-old WT, amIR1-4, and amiR1-4/Os31K plants. Bar = 50 µm.
