Development of Scutellar Epithelial Cells during Rice Embryogenesis, Studied by Chemical Fixation and Freeze-substitution Methods
Cuticular layer Freeze-substitution Oryza sativa Scutellar epithelial cell Tiny cell wall ingrowth
2009/8/5
The whole surface of rice embryo was continuously covered with a cuticular layer until 4 days after anthesis. The cuticular layer became intermittent at only the abaxial side of scutellum at 5 days an...
Studies on the Mechanism of Salt Tolerance in Salicornia europaea L:II. High osmosis of epidermal cells in stem
Epidermal cell Halophyte Inorganic ions Plasmolysis Salicornia
2009/7/31
To understand how cells sense and respond to salt stress, we investigate changes in plasmolitic concentration to NaCl of epidermal cells in Salicornia europaea during the growth period. The inorganic ...
