	abstract = {The large megasporocytes of Isoetes provide an exceptional system for studying microtubule dynamics in monoplastidic meiosis where plastid polarity assures coordination of plastid and nuclear division by the intimate association of MTOCs with plastids. Division and migration of the plastid in prophase establishes the tetrahedrally arranged cytoplasmic domains of the future spore tetrad and the four plastid-MTOCs serve as focal points of a unique quadripolar microtubule system (QMS). The QMS is a dynamic structure which functions in plastid deployment and contributes directly to development of both first and second division spindles. The nucleation of microtubules at discrete plastid-MTOCs is compared with centrosomal nucleation of microtubules in animal cells where growth of microtubules involves dynamic instability. {\textcopyright} 1989 Springer-Verlag.},

	abstract = {Mitosis in monoplastidic root tip cells of Isoetes was studied by fluorescence (confocal laser scanning microscopy) and transmission electron microscopy. The two major components of division polarity, spindle axis and division site, are established more or less simultaneously in preprophase. Morphogenetic plastid migration results in positioning of a daughter plastid at each pole of the future spindle. Concomitant with establishment of the spindle axis, the division site is marked by a girdling band of mirotubules (preprophase band). Endoplasmic microtubules interconnect the polar plastids and preprophase band suggesting a mechanism for communication and final alignment of spindle axis and division site. As in other monoplastidic cells, the spindle appears to emanate from the plastids. In telophase, the focus of microtubules shifts to the reforming nuclei as the phragmoplast is initiated. Microtubules which continue to emanate from plastids are incorporated into the phragmoplast as it expands beyond the interzonal region. Cortical microtubules are restored in a random fashion before assuming a transverse arrangement in interphase. {\textcopyright} 1992 Springer-Verlag.},
