Myosins XI-K, XI-1, and XI-2 are required for development of pavement cells, trichomes, and stigmatic papillae in Arabidopsis [PDF]

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 ...

Four-dimensional phenotyping reveals MYOSIN XI-dependent establishment of branch morphology through upward- and stably-directed growth in Arabidopsis [PDF]

Quantitative Plant Biology
Plants 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 ...

Rab-E and its interaction with myosin XI are essential for polarised cell growth. [PDF]

New Phytol, 2021
Summary The fundamental process of polarised exocytosis requires the interconnected activity of molecular motors trafficking vesicular cargo within a dynamic cytoskeletal network. In plants, few mechanistic details are known about how molecular motors, such as myosin XI, associate with their secretory cargo to support the ubiquitous processes of ...

Arabidopsis myosin XI sub-domains homologous to the yeast myo2p organelle inheritance sub-domain target subcellular structures in plant cells [PDF]

Frontiers in Plant Science, 2013
Myosin XI motor proteins transport plant organelles on the actin cytoskeleton. The Arabidopsis gene family that encodes myosin XI has 13 members, 12 of which have sub-domains within the tail region that are homologous to well-characterized cargo-binding ...

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 Communications
Agrobacterium 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 ...

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.

Identification and intracellular functional characterization of myosin XI and VIII in the lycophyte Selaginella moellendorffii. [PDF]

Planta
Selaginella moellendorffii myosins retain conserved intracellular functions of known plant myosins, while lycophytes possess a unique myosin VIII with an extended neck domain. Research on plant myosins has primarily focused on model species, such as green algae, mosses, and seed plants.

Dynamics of full-length Arabidopsis myosin XI and its involvement in actin remodeling. [PDF]

Plant Cell Physiol
Abstract Plant myosin XI plays a crucial role in intracellular transport, known as cytoplasmic streaming. Previous studies have identified associations between myosin XI and organelles by using a cargo-binding tail domain that lacks a motor domain.

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 ...
