| Popis: | Significance We report cell-to-cell movement of mitochondria through a graft junction of two tobacco species, Nicotiana tabacum and Nicotiana sylvestris . The flowers of the N. tabacum line we used are male sterile due to a sterility-causing mitochondrial genome, whereas the N. sylvestris flowers are fertile. Grafting created an opportunity for organelle movement during the healing process when cell-to-cell connections at the graft junction were restored. We recognized N. sylvestris mitochondrial DNA transfer by restoration of fertile flower anatomy in plants regenerated from graft junctions. Demonstrating cell-to-cell movement of mitochondria reconstructs the evolutionary process of horizontal mitochondrial DNA transfer and enables modification of mitochondria by DNA acquired from other species. |
