Impact of nuclear actin on the prophase chromosome construction of Physarum polycephalum

A cell-free system efficiently promoting mitosis has been developed using the precise natural synchronous plasmodium of Physarum polycephalum. The content changes of nuclear cyclin B were exploited to represent the prophase process of Physarum polycephalum. The possible function of nuclear actin on chromosome construction was investigated by detecting the content changes of nuclear cyclin B in the late G2 phase nuclei treated with cytochalasin B and incubated in the cell-free system. Our results showed that nuclear actin plays an important role in the process of the chromosome construction.
