Mitosis is nuclear division plus cytokinesis,and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. However, a new nucleus behavior in interspecific hybrid progenies of Lilium was observed in our experiment. Very unusual behaviors of nuclei surprisingly presented during the mitosis, such as sprouting or germination, tube-like elongation, penetrating cell membrane into a neighbor cell, the top of nuclei tube expanding, intruding and splitting of the tube-like nucleus, and micronucleus formation, and so on. Furthermore, the tetrad of meiosis was founded in mitosis of root.

Routine of the unusual nucleus behaviors observed in our experiment may be summarized as nucleus...
