| Outline of Final Research Achievements |
In animal cells, the retrograde transport of intracellular cargo along microtubules is executed by the cytoplasmic dynein motor (retrograde transport is transport towards the minus end of the microtubule). Interestingly, however, land plants have lost the cytoplasmic dynein gene, despite that they execute retrograde transport. In this research, we aim to identify the motor(s) responsible for retrograde transport in plants. Using he moss Physcomitrella patens, we identified three kinesin-14 motor proteins (KCBP, KCH, ATK) that were required for retrograde transport of the nucleus, chloroplast, and microtubule itself in the moss cytoplasm.
