Myosin XI Is Essential for Tip Growth inPhyscomitrella patens [PDF]
The Plant Cell, 2010 AbstractClass XI myosins are plant specific and responsible for cytoplasmic streaming. Because of the large number of myosin XI genes in angiosperms, it has been difficult to determine their precise role, particularly with respect to tip growth. The moss Physcomitrella patens provides an ideal system to study myosin XI function. P.

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.

Myosin XI Is Required for Actin-Associated Movement of Plastid Stromules [PDF]
Molecular Plant, 2009 Stromules are highly dynamic stroma-filled tubules extending from the surface of plastids and occasionally interconnecting individual plastids, allowing the movement of complex biological molecules between the interconnected plastids. Experiments with inhibitors of cytoskeleton assembly have indicated the involvement of an actin-based system in ...

Four-dimensional phenotyping reveals MYOSIN XI-dependent establishment of branch morphology through upward- and stably-directed growth in Arabidopsis [PDF]
Quantitative Plant BiologyPlants develop characteristic shoot architectures by extending branches at specific angles. Primary shoots bend in response to gravity and then adjust the orientation through an organ-straightening process to achieve a mechanically favorable shape ...

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 ...

Myosin VIII and XI isoforms interact with the Agrobacterium VirE2 protein and facilitate its transport from the plasma membrane to the perinuclear region during plant transformation [PDF]
Plant CommunicationsAgrobacterium transfers single-stranded T-DNA (T-strands) and virulence effector proteins into plant cells. VirE2, a key effector protein, enters the plant cell and is thought to bind T-strands, protecting them from nuclease degradation and guiding them ...

Myosins XI-K, XI-1, and XI-2 are required for development of pavement cells, trichomes, and stigmatic papillae in
BMC Plant Biology, 2012 Background The positioning and dynamics of vesicles and organelles, and thus the growth of plant cells, is mediated by the acto-myosin system. In Arabidopsis there are 13 class XI myosins which mediate vesicle and organelle transport in different cell ...

Functions of plant-specific myosin XI: from intracellular motility to plant postures [PDF]
Current Opinion in Plant Biology, 2015 The plant-specific protein motor class myosin XI is known to function in rapid bulk flow of the cytoplasm (cytoplasmic streaming) and in organellar movements. Recent studies unveiled a wide range of physiological functions of myosin XI motors, from intracellular motility to organ movements. Arabidopsis thaliana has 13 members of myosin XI class.

Arabidopsis thaliana myosin XIK is recruited to the Golgi through interaction with a MyoB receptor [PDF]
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

Myosin XI is associated with fitness and adaptation to aridity in wild pearl millet. [PDF]
Heredity (Edinb), 2017 Phenotypic changes in plants can be observed along many environmental gradients and are determined by both environmental and genetic factors. The identification of alleles associated with phenotypic variations is a rapidly developing area of research.
