Phragmoplast microtubules
Cell plate (presumptive callose).Note weaker orange signal in the cell plate's center, indicating that callose is transiently deposited at the more newly formed periphery of the centrifugally expanding cell plate, while it is being replaced in the older, more central regions (perhaps by polysaccharides characteristic of more mature cell walls).
(The scattered orange and yellow noise that sweeps by in the fore- and background is artifact from other material in the optical sections.)

| Though this one is in black and white, it strikingly illustrates that the cell plate is somehow suspended by the phragmoplast. Observe the presumptive callose "rafts" on the less visible cell plate that appears to be suspended by the phragmoplast microtubules. There is a readily noticeable gap between the microtubules of the upper and lower phragmoplast halves. The cell plate appears to insert at the gap. Also note that the specimen appears flattened on a side by the cover of the microslide. |
