Fig. 5. Steady-state level of PsbS protein in mesophyll and bundle sheath cells of maize leaves under drought stress
A: Immunoblot analyses of PsbS in mesophyll cells (1.0 μg Chl); B: Immunoblot analyses of PsbS in bundle sheath cells (1.5 μg Chl); C: Quantification of PsbS immunoblot signal in mesophyll cells (the amount of the PsbS protein in mesophyll cells of Chengdan 30 maize under well watered condition was defined as 100%); D: Quantification of PsbS immunoblot signal in bundle sheath cells (the amount of the PsbS protein in bundle sheath cells of Chengdan 30 maize under well watered condition was defined as 100%). Coomassie blue staining (CBS) of protein samples were shown as the control
