Graphs showing quantitative data obtained from electron microscopy of in situ immunolocalization of glycine decarboxylase (GDC) in mesophyll (M) versus bundle sheath (BS) of Salsola species s.l., S. masenderanica, S. montana, and S. webbii, M versus Kranz-like cells (KLCs) of S. divaricata in section Coccosalsola, and M versus Kranz cells (KCs) in the C₄ Salsoloid-type species Caroxylon orientale. The density of labelling (number of gold particles per μm² of mitochondrial area) for GDC in mitochondria in the chlorenchyma cell types is shown. For each cell type, 10–15 cell fragments were used for counting.
