Myosin-dependent endoplasmic reticulum motility and F-actin organization in plant cells
TLDR
A model whereby dynamic three-way interactions between ER, F-actin, and myosins determine the architecture and movement patterns of the ER strands, and cause cytosol hauling traditionally defined as cytoplasmic streaming is suggested. Expand
Myosin XI-i Links the Nuclear Membrane to the Cytoskeleton to Control Nuclear Movement and Shape in Arabidopsis
TLDR
A new type of nucleocytoplasmic linker consisting of a myosin motor and nuclear membrane proteins is described, which might enable rapid nuclear positioning in response to environmental stimuli in plants. Expand
Vacuolar SNAREs function in the formation of the leaf vascular network by regulating auxin distribution.
TLDR
It is shown that vacuolar SNAREs (soluble N-ethylmaleimide-sensitive factor attachment protein receptors), VAM3 and VTI11, are required for the formation of the leaf vascular network in a dosage-dependent manner and that PIN1 proteins were constitutively transported to vacuoles in leaf and roots cells. Expand
AtVAM3 is required for normal specification of idioblasts, myrosin cells.
TLDR
The results suggest that AtVAM3 has a plant-specific function in development of myrosin cells, and are suggested to be responsible for the abnormal abundance of TGGs and the reduction of elongation of inflorescence stems and leaves in atvam3 mutants. Expand
GNOM-LIKE1/ERMO1 and SEC24a/ERMO2 Are Required for Maintenance of Endoplasmic Reticulum Morphology in Arabidopsis thaliana[W]
TLDR
It is suggested that GNL1/ER MO1 and SEC24a/ERMO2 have a novel function in ER morphology in higher plants, similar to that in yeast and animal cells. Expand
Regulation of organ straightening and plant posture by an actin–myosin XI cytoskeleton
TLDR
This work shows that the straightening of inflorescence stems is regulated by an actin–myosin XI cytoskeleton in specialized immature fibre cells that are parallel to the stem and encircle it in a thin band. Expand
MAIGO2 Is Involved in Exit of Seed Storage Proteins from the Endoplasmic Reticulum in Arabidopsis thaliana[W][OA]
TLDR
The findings suggest that MAG2 functions in the transport of storage protein precursors between the ER and Golgi complex in plants. Expand
Identification of an allele of VAM3/SYP22 that confers a semi-dwarf phenotype in Arabidopsis thaliana.
TLDR
It is suggested that VAM3/SYP22 and SYP23 have overlapping functions and that the vesicle transport mediated by these syntaxins is important for shoot morphogenesis. Expand
Arabidopsis Qa-SNARE SYP2 proteins localized to different subcellular regions function redundantly in vacuolar protein sorting and plant development.
TLDR
SyP2 proteins, including cytosolic SYP23/PLP, appear to function redundantly in vacuolar trafficking and plant development and it is found that expression of multiple copies of a genomic fragment of SYP21/pep12 suppressed the abnormal syp22-3 phenotype. Expand
Plant-specific insertions in the soybean aspartic proteinases, soyAP1 and soyAP2, perform different functions of vacuolar targeting.
TLDR
Observations indicated that, in the case of soyAP1, the PSI is not involved in vacuolar targeting, also suggesting that the function of thePSI differs depending on its origin. Expand
