Effect of Different Gravity Environments on DNA Fragmentation and Cell Death in Kalanchoë Leaves

Different gravity environments have been shown to significantly affect leaf-plantlet formation and asexual reproduction in Kalanchoë daigremontiana Ham. and Perr. In the present work, we investigated the effect of gravity at tissue and cell levels. Leaves and leaf-plantlets were cultured for differe...
