    A model for how the constant nuclear/cell volume can affect nuclear shapeIn yeast, and possibly other cells, there is a constant ratio between nuclear and cell volume.  If nuclear surface area increases the nucleus could expand, increasing its volume or the nuclear envelope could form protrusions and invaginations.  We propose that the latter happens to maintain a constant nuclear/cell volume ratio.A model for how the constant nuclear/cell volume can affect nuclear shapeEnlarge
