A：1%DDM增溶后经4%—12%蓝-绿胶温和电泳分离的叶肉细胞类囊体膜蛋白;B：2%DDM增溶后经4%—12%蓝-绿胶温和电泳分离的维管束鞘细胞类囊体膜蛋白;C：叶肉细胞类囊体膜LHCII三聚体稳态水平分析（充足浇水条件下的LHCII三聚体水平定义为100%）;D：维管束鞘细胞类囊体膜LHCII三聚体稳态水平分析（充足浇水条件下的LHCII三聚体水平定义为100%）

Fig. 6. Steady-state levels of PSII complexes in mesophyll and bundle sheath cells of maize leaves under drought stress
A: Membranes in mesophyll thylakoids were solubilized with 1% DDM and loaded onto 4%-12% acrylamide Blue-Native gel; B: Membranes in bundle sheath thylakoids were solubilized with 2% DDM and loaded onto 4%-12% acrylamide Blue-Native gel; C: Quantification of LHCII trimer in mesophyll thylakoids (the amount of the LHCII trimer under well watered condition was defined as 100%); D: Quantification of LHCII trimer in bundle sheath thylakoids (the amount of the LHCII trimer under well watered condition was defined as 100%)
