Webb1 jan. 1999 · Features, development, and functions of preprophase bands (PPBs) of microtubules (MTs) are reviewed. The PPB is an array of cortical MTs in higher plants that appears in G 2 and prophase and predicts where the cell plate will be inserted (the division site). Experimental obliteration of the PPB causes misplacement of cell plate insertion, … WebbThe better known microtubule cycle is associated with control of the future division plane in meristematic growth where new cells become part of tissues. The future daughter domains are determined before the nucleus enters prophase and the future site of cytokinesis is marked by a preprophase band (PPB) of cortical microtubules.
