FIGURE 7.
Accumulation of ROS and pharmacological interference with ROS compromised tapetal PCD in K87B1-706A, Ju87B1-706A, and 706B during various developmental stages. Tds, tetrad stage; Ens, early uninucleate stage; Lns, late uninucleate stage; Bns, binucleate stage; and Tns, trinucleate stage. O2- contents (A); H2O2 contents (B); and MDA contents (C). ∗P < 0.05; ∗∗P < 0.01. Detection of DNA laddering in the DPI-treated anther from K87B1-706A and Ju87B1-706A (D). M, Marker D2000.
