In this study we show that in classical cytokinin bioassays, nebularine antagonized cytokinin function in senescence and callus biotests but not in the Amaranthus bioassay. Nebularine reversed the inhibitory effect of cytokinin on lateral root formation in Arabidopsis seedlings, and when applied alone caused increased lateral root formation and shortening of the main root. Systematic spraying of Arabidopsis plants with nebularine led to yellowing and formation of purple pigments, local drying, and withering, although younger plants showed a greater resilience. Comparison of nebularine cytotoxicity in plant and animal cells showed that the growth of tobacco BY-2 cells was inhibited with only about tenfold lower efficacy than mammalian cell lines.
