Abstract

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.
