TEM of tissue from shoot tips of spring shoots. (A) the cell from AZ before self-pruning; (B) nucleolus begin death; (C–F) vacuole, karyotheca, mitochondria, and chloroplasts began to break, respectively; (E) the cells with dying bodies; (F) the completely dead cells; (G) cells with dying bodies; (H) the completely dead cells; (I) results of DNA electrophoresis of shoot tip, Dl2000 DNA molecular ladder was applied to the run, lanes 1 and 2: DNA isolated before self-pruning of shoot tip; lanes 3 and 4: DNA isolated at the start of self-pruning of the shoot tip. Cell organelle labeling: Ch, chloroplast; Va, vacuole; Mi, mitochondria; Nu, nucleus; Ka, karyotheca. Bars are 2 μm in A, G and H, 0.5 μm in C-E and 200 nm in F.
