Abstract/OtherAbstract:
The preprophase band and mitotic spindle of dividing protodermal cells of wild-type Zea mays leaves include few actin filaments. Surprisingly, abundant actin filaments were observed in the above arrays, in dividing protodermal cells in the leaves of the brick1 mutant. The same abundance was observed in the spindle of Taxol-treated brick1 mitotic protodermal cells. Apart from the above difference, the relevant arrays displayed normal microtubule organization in both wild type and mutant cells, as far as can be discerned by immunofluorescence microscopy. Accordingly, the abundance of actin filaments in the preprophase band and spindle of brick1 mitotic cells seems not to influence the structure of the above arrays and might be a non-functional "side-effect" of defective F-actin organization in this mutant.
