Why Do Nuclear Vacuoles Appear in the Prophasic Nucleus of Pollen Mother Cells? Facts and Hypotheses

The presence of nuclear vacuoles during meiotic prophase has been shown in both animal (Rasmussen, 1976) and plant cells, including ferns (Sheffield and Bell, 1979; Sheffield, Laird and Bell, 1983), gymnosperms and angiosperms (Sheffield et al., 1979; Karasawa and Ueda, 1983a; Karasawa and Ueda, 1983b; Sangwan, 1986). An intimate relationship between the appearance of nuclear vacuoles and meiotic processes seems to be a common feature of all cells. Although there is no lack of hypotheses put forth by different authors, the whys and wherefores of these structures have yet to be satisfactorily explained.
