BMC Plant Biology, 2008 Background The cytoskeletal mechanisms that underlie organelle transport in plants are intimately linked to acto-myosin function. This function is mediated by the attachment of myosin heads to F-actin and the binding of cargo to the tails.

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.

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 ...

Myosins VIII and XI play distinct roles in reproduction and transport of tobacco mosaic virus.
PLoS Pathogens, 2014 Viruses are obligatory parasites that depend on host cellular factors for their replication as well as for their local and systemic movement to establish infection.

Actin–myosin XI: an intracellular control network in plants
Biochemical and Biophysical Research Communications, 2018 Actin is one of the three major cytoskeletal components in eukaryotic cells. Myosin XI is an actin-based motor protein in plant cells. Organelles are attached to myosin XI and translocated along the actin filaments. This dynamic actin-myosin XI system plays a major role in subcellular organelle transport and cytoplasmic streaming. Previous studies have

Skeletal muscle myosin promotes coagulation by binding factor XI via its A3 domain and enhancing thrombin-induced factor XI activation [PDF]
Journal of Biological Chemistry, 2022 Skeletal muscle myosin (SkM) has been shown to possess procoagulant activity; however, the mechanisms of this coagulation-enhancing activity involving plasma coagulation pathways and factors are incompletely understood. Here, we discovered direct interactions between immobilized SkM and coagulation factor XI (FXI) using biolayer interferometry (Kd = 0 ...

Investigating the role of uncoupling of troponin I phosphorylation from changes in myofibrillar Ca(2+)-sensitivity in the pathogenesis of cardiomyopathy. [PDF]
, 2014 Contraction in the mammalian heart is controlled by the intracellular Ca2+ concentration as it is in all striated muscle, but the heart has an additional signalling system that comes into play to increase heart rate and cardiac output during exercise or ...

Differential gene expression in tall fescue tissues in response to water deficit
The Plant Genome, 2022 Tall fescue (Festuca arundinacea Schreb.) is a popular pasture and turf grass particularly known for drought resistance, allowing for its persistence in locations that are unfavorable for other cool‐season grasses.

Dissecting the Functions of Class XI Myosins in Moss and Arabidopsis [PDF]
The Plant Cell, 2010 Myosin XI strides along actin tracks at rates of up to 7 μm/s, making it the fastest known processive molecular motor ([Tominaga et al., 2003][1]). Class XI myosins are unique to plants and have been implicated in plant growth, intracellular transport, and root hair elongation ([Prokhnevsky et ...
