Reversibility of male sterility after 10 d under continuous illumination. A, Transgenic flower after 9 d in continuous light; note normal length of the anther filaments and pollen grains. B, Fully developed fruit capsules containing seeds from reversed transgenic lines. C, Abundant seeds from a transgenic fruit capsule. D, Seedlings produced via the reversibility to male fertility. Transgenic seeds germinated in Murashige and Skoog medium supplied were with 500 μg/mL spectinomycin. E, Bleached wild-type tobacco seedlings.
