1. Tissue expression pattern of SOS1.
Tissue expression pattern of SOS1. A to K, Representative images of staining patterns resulting from GUS expression under the control of the SOS1 gene promoter. A and B, Preferential expression around the root vascular bundle. C, Root cross section. D and E, Lack of staining in undifferentiated tissues near the root cap and in root hairs. F to H, Staining indicates that expression of SOS1 correlates with the differentiation of vascular bundles in secondary roots. I, Scattered expression around the vasculature of the coleoptile. J, Vascular bundles of the flag leaf. K, Strong expression in leaf xylem parenchyma. Arrowheads point to nonstained stomata. Scale bars =100 µm.
