In plant cells, the plane of division is anticipated at the onset of mitosis by the presence of a preprophase band (PPB) of microtubules and F-actin at a cortical site that circumscribes the nucleus. During cytokinesis, the microtubule- and F-actin-based phragmoplast facilitates construction of a new cell wall and is guided to the forecast division site. Proper execution of this process is essential for establishing the cellular framework of plant tissues. The microtubule binding protein TANGLED1 (TAN1) of maize is a key player in the determination of division planes . Lack of TAN1 leads to misguided phragmoplasts and mispositioned cell walls in maize. In a yeast two-hybrid screen for TAN1-interacting proteins, a pair of related kinesins was identified that shares significant sequence homology with two kinesin-12 genes in Arabidopsis thaliana (A. thaliana): PHRAGMOPLAST ORIENTING KINESIN 1 and 2 (POK1, POK2). POK1 and POK2 are expressed in tissues enriched for dividing cells. The phenotype of pok1;pok2 double mutants strongly resembles that of maize tan1 mutants, characterized by misoriented mitotic cytoskeletal arrays and misplaced cell walls. We propose that POK1 and POK2 participate in the spatial control of cytokinesis, perhaps via an interaction with the A. thaliana TAN1 homolog, ATN.
