Functions of plant-specific myosin XI: from intracellular motility to plant postures

- Myosin XI family has roles from intracellular motility to organ movements.
- Myosins XIk, XI1, and XI2 drive ER streaming by organizing actin bundles.
- Myosin XIk is a primary contributor to cytoplasmic streaming in vegetative organs.
- Myosin XI-i is a nucleocytoplasmic linker that regulates nuclear shape and movement.
- Myosins XIf and XIk regulate organ straightening to determine plant postures.
