ER network dynamics are differentially controlled by myosins XI-K, XI-C, XI-E, XI-I, XI-1 and XI-2 [PDF]
Frontiers in Plant Science, 2014 The endoplasmic reticulum (ER) of higher plants is a complex network of tubules and cisternae. Some of the tubules and cisternae are relatively persistent, while others are dynamically moving and remodelling through growth and shrinkage, cycles of ...

Analysis of Organelle Targeting by DIL Domains of the Arabidopsis Myosin XI Family. [PDF]
Front Plant Sci, 2011 The Arabidopsis thaliana genome encodes 13 myosin XI motor proteins. Previous insertional mutant analysis has implicated substantial redundancy of function of plant myosin XIs in transport of intracellular organelles.

Unraveling the fastest myosin: Discovery history and structure-function relationships of algae Chara myosin XI. [PDF]
Biophys PhysicobiolPlant myosins have higher velocities than animal myosins. Among them, myosins in freshwater algae of the genus Chara have extremely high velocities. We have biochemically studied myosins that perform high-speed movements in the alga Chara.

Arabidopsis Myosin XI-K Localizes to the Motile Endomembrane Vesicles Associated with F-actin. [PDF]
Front Plant Sci, 2012 Plant myosins XI were implicated in cell growth, F-actin organization, and organelle transport, with myosin XI-K being a critical contributor to each of these processes.

Autoregulation and dual stepping mode of MYA2, an Arabidopsis myosin XI responsible for cytoplasmic streaming. [PDF]
Sci Rep, 2022 Arabidopsis thaliana has 13 genes belonging to the myosin XI family. Myosin XI-2 (MYA2) plays a major role in the generation of cytoplasmic streaming in Arabidopsis cells.

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

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 CommunAgrobacterium 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 ...

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