2008, Molecular PlantCitation Excerpt :Further evidence for forces between the PPB and prophase spindle comes from the observation that the less structurally cohesive spindles of atk5-1 are prone to deformation toward the close PPB in cells with off-centered prophase nuclei (Figure 6). Other studies have also provided evidence for attractive forces between the nucleus and PPB: (1) laser microsurgery experiments wherein the cytoplasmic strands rapidly recoil upon laser ablation (Goodbody et al., 1991; Hahne and Hoffmann, 1984); (2) prophase nuclei become distorted into an elliptical shape along the plane of the PPB, suggesting the presence of pulling forces acting on the nucleus along the plane of the PPB (Burgess, 1970; Panteris et al., 1991); (3) association of PPBs with isolated prophase nuclei, indicating a physical link between the two (Wick and Duniec, 1984); and (4) reduced organelle motility within mature phragmosomes (Mineyuki et al., 1994; Ota, 1961) and resistance of prophase nuclei to centrifugation, suggesting increased gelation and tensile forces between the PPB and prophase spindle (Mineyuki and Furuya, 1986; Mineyuki and Palevitz, 1990; Pickett-Heaps, 1969). Although these findings provide compelling evidence for tensile forces between the PPB and prophase spindle mediated by bridge MTs, further studies are required to elucidate the molecular players governing the creation of bipolarity along an axis perpendicular to the plane of the PPB.
