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.

Frontiers in Plant Science, 2021 Post-embryonic cells contain minute lipid bodies (LBs) that are transient, mobile, engage in organellar interactions, and target plasmodesmata (PD). While LBs can deliver γ-clade 1,3-β-glucanases to PD, the nature of other cargo is elusive.

Myosin-Powered Membrane Compartment Drives Cytoplasmic Streaming, Cell Expansion and Plant Development. [PDF]
PLoS ONE, 2015 Using genetic approaches, particle image velocimetry and an inert tracer of cytoplasmic streaming, we have made a mechanistic connection between the motor proteins (myosins XI), cargo transported by these motors (distinct endomembrane compartment defined

Movement of Lipid Droplets in the Arabidopsis Pollen Tube Is Dependent on the Actomyosin System
Plants, 2023 The growth of pollen tubes, which depends on actin filaments, is pivotal for plant reproduction. Pharmacological experiments showed that while oryzalin and brefeldin A treatments had no significant effect on the lipid droplets (LDs) trafficking, while 2 ...

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 ...

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

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.

Myosin XI-2 is implicated in TuMV intercellular movement.
, 2013 (A) Quantitative RT-PCR was used to determine the relative expression ratio of target genes (myosin VIII-1, myosin VIII-2, myosin XI-2, and myosin XI-F) in N.

Class XI Myosins Contribute to Auxin Response and Senescence-Induced Cell Death in Arabidopsis
Frontiers in Plant Science, 2018 The integrity and dynamics of actin cytoskeleton is necessary not only for plant cell architecture but also for membrane trafficking-mediated processes such as polar auxin transport, senescence, and cell death.
