A SNARE Complex Unique to Seed Plants Is Required for Protein Storage Vacuole Biogenesis and Seed Development of Arabidopsis thaliana[W][OA]
TLDR
It is suggested that the VAMP727 complex mediates the membrane fusion between the prevacuolar compartment and the vacuole and that this process has evolved as an essential step for seed development.

TLDR
These findings suggest that plants evolved a unique actin-based mechanism for organelle movement, associated with chloroplast photorelocation and anchoring to the plasma membrane.
The ANGUSTIFOLIA gene of Arabidopsis, a plant CtBP gene, regulates leaf‐cell expansion, the arrangement of cortical microtubules in leaf cells and expression of a gene involved in cell‐wall formation
TLDR
It is found that the abnormal arrangement of cortical microtubules in an leaf cells appeared to account entirely for the abnormal shape of the cells, and it was suggested that the AN gene might regulate the polarity of cell growth by controlling the arrangement of cortex MTs.
cis-Golgi proteins accumulate near the ER exit sites and act as the scaffold for Golgi regeneration after brefeldin A treatment in tobacco BY-2 cells
Particular cis-Golgi proteins accumulate in novel punctate structures close to ERES by BFA treatment in tobacco BY-2 cells. These structures reassemble first to form cis-Golgi after BFA removal, and
Heteroblasty in Arabidopsis thaliana (L.) Heynh
TLDR
The results suggest that heteroblasty in foliage leaves might be affected in part by the heteroblastic stage of the preceding foliage leaves but is finally controlled autonomously at each leaf position.
A Missense Mutation in the NSF Gene Causes Abnormal Golgi Morphology in Arabidopsis thaliana.
TLDR
The mutant phenotype of #46-3 is linked to the missense mutation D374N in the NSF gene, encoding the N-ethylmaleimide-sensitive factor (NSF), a key component of membrane fusion, suggesting that the biochemical function of NSF is important for maintaining the normal morphology of the Golgi.
Two new coral fluorescent proteins of distinct colors for sharp visualization of cell-cycle progression
TLDR
A new color variant of Fucci (Fluorescent Ubiquitination-based Cell-Cycle Indicator): Fucci5 was found to provide brighter nuclear labeling for monitoring cell cycle progression than the 1st and 2nd generations that used mAG/mKO2 and mVenus/mCherry, respectively.
Engineering a genetically-encoded SHG chromophore by electrostatic targeting to the membrane
TLDR
Inspired by the mechanism by which K-Ras4B associates with plasma membranes, this work sought to achieve asymmetric arrangements of chromophores at the membrane-cytoplasm interface using the fluorescent protein mVenus, which efficiently targeted to the plasma membrane in a geometrically defined manner and exhibited SHG in HEK293 cells.
