PSI activity and PsaA protein levels in leaves after high light and dark-submergence treatment.

<p>PSI activity (Activity of PSI Complex) and PsaA protein levels in daylily and maize leaves after high light (HL) and dark-submergence treatment (DST). (A) Changes of photochemical efficiency in daylily and maize leaves. CK0, the control leaves placed in the humid-dark air for 3 h; HL, leaves after high light (1000 µmol m⁻² s⁻¹) treatment for 3 h; CK1, the control leaves placed in the humid-dark air for 36 h; DST, leaves after DST for 36 h. Means ± SE of eight replicates are presented. Different letters indicate significant differences between treatments, P<0.05. The differences were analyzed by least significant difference (LSD). (B) Changes of the D1 protein content after high light (HL) and dark-submergence treatment (DST). (C) Quantitative image analysis of protein levels for Fig. 10B. Means ± SE of three replicates are presented. Different letters indicate significant differences between the treatments, P<0.05. Differences were analyzed by least significant difference (LSD).
