Enzymatic Activity and Motility of Recombinant Arabidopsis Myosin XI, MYA1 [PDF]
Plant and Cell Physiology, 2007 We expressed recombinant Arabidopsis myosin XI (MYA1), in which the motor domain of MYA1 was connected to an artificial lever arm composed of triple helical repeats of Dictyostelium alpha-actinin, in order to understand its motor activity and intracellular function.

Arabidopsis Myosin XI: A Motor Rules the Tracks [PDF]
PLANT PHYSIOLOGY, 2014 Plant cell expansion relies on intracellular trafficking of vesicles and macromolecules, which requires myosin motors and a dynamic actin network. Arabidopsis (Arabidopsis thaliana) myosin XI powers the motility of diverse cellular organelles, including endoplasmic reticulum, Golgi, endomembrane vesicles, peroxisomes, and mitochondria.

Myosins XI Are Involved in Exocytosis of Cellulose Synthase Complexes [PDF]
Plant Physiology, 2019 In plants, cellulose is synthesized at the cell surface by plasma membrane (PM)-localized cellulose synthase (CESA) complexes (CSCs). The molecular and cellular mechanisms that underpin delivery of CSCs to the PM, however, are poorly understood. Cortical microtubules have been shown to interact with CESA-containing compartments and mark the site for ...

Tubule-guided cell-to-cell movement of a plant virus requires class XI myosin motors. [PDF]
PLoS Pathogens, 2011 Cell-to-cell movement of plant viruses occurs via plasmodesmata (PD), organelles that evolved to facilitate intercellular communications. Viral movement proteins (MP) modify PD to allow passage of the virus particles or nucleoproteins.

Functional Diversity of Class XI Myosins in Arabidopsis thaliana [PDF]
Plant and Cell Physiology, 2018 Plant myosin XI acts as a motive force for cytoplasmic streaming through interacting with actin filaments within the cell. Arabidopsis thaliana (At) has 13 genes belonging to the myosin XI family. Previous reverse genetic approaches suggest that At myosin XIs are partially redundant, but are functionally diverse for their specific tasks within the ...

Arabidopsis thaliana myosin XIK is recruited to the Golgi through interaction with a MyoB receptor
Communications Biology, 2021 Perico et al. use co-expression analysis and a FRET-FLIM approach to show that the Arabidopsis MyoB myosin receptor, MRF7, triggers the relocation of Myosin XI-K to the Golgi. As such, this study provides evidence for plant myosin recruitment and control

Evolutionary traces decode molecular mechanism behind fast pace of myosin XI. [PDF]
BMC Struct Biol, 2011 Cytoplasmic class XI myosins are the fastest processive motors known. This class functions in high-velocity cytoplasmic streaming in various plant cells from algae to angiosperms. The velocities at which they process are ten times faster than its closest class V homologues.To provide sequence determinants and structural rationale for the molecular ...

Dynamics of Myosin XI: The Family Speed Demon [PDF]
Biophysical Journal, 2014 Myosin XI is the fastest known processive motor, and is implicated in organelle transport and propulsion of cytoplasmic streaming in plant cells. We studied the motility and dynamics of a recombinant myosin XI motor domain hybridized with the myosin Va lever arm with 6 calmodulin-bearing IQ motifs and the dimerization motif.

Contribution of host intracellular transport machineries to intercellular movement of turnip mosaic virus. [PDF]
PLoS Pathogens, 2013 The contribution of different host cell transport systems in the intercellular movement of turnip mosaic virus (TuMV) was investigated. To discriminate between primary infections and secondary infections associated with the virus intercellular movement ...

Plant Lipid Bodies Traffic on Actin to Plasmodesmata Motorized by Myosin XIs [PDF]
International Journal of Molecular Sciences, 2020 Late 19th-century cytologists observed tiny oil drops in shoot parenchyma and seeds, but it was discovered only in 1972 that they were bound by a half unit-membrane. Later, it was found that lipid bodies (LBs) arise from the endoplasmic reticulum. Seeds are known to be packed with static LBs, coated with the LB-specific protein OLEOSIN.
