At the beginning of preprophase, the cortical microtubules of a plant cell disappear and aggregate into a dense ring underneath the plasma membrane. This preprophase band runs around the equatorial plane of the future mitotic spindle and marks the plane of cell division and future fusion site for the cell plate. It consists of microtubules and microfilaments (actin) and persists into prophase. Spindle formation occurs during prophase with the axis perpendicular to the plane sur… Webb11 juni 2024 · In a plant cell, a structure called the preprophase band marks the division zone when the cell is about to divide ( Figure 2A ). Structures called microtubules and microfilaments make up the preprophase band. Once the division zone is formed, the preprophase band disappears.

Webb1 feb. 2001 · Many premitotic plant cells possess a cortical preprophase band of microtubules and actin filaments that encircles the nucleus. In vacuolated cells, the preprophase band is visibly connected to the nucleus by a cytoplasmic raft of actin filaments and microtubules termed the phragmosome.
