Fig. 6: TEM observation of the chloroplasts in the meristem.
From: Mutation of SlARC6 leads to tissue-specific defects in chloroplast development in tomato

TEM micrographs showing longitudinal sections of the shoot apical meristem in WT (A, B) and su mutants (C, D). B, D The upper right insets show the chloroplast in the shoot apical meristem (bar: 1 μm). n nucleus. The red triangles point to the proplastids and chloroplasts. Bar: 10 μm. E, F TEM micrographs showing the transverse section of the region beneath the meristem. The red stars mark the chloroplast. Bar: 10 μm. G Schematic showing the position of TEM observations in the meristem. The yellow square shows the position of images in A–D. The green square shows the position of images in E, F
