author keywords: Arabidopsis; vacuole fusion; HOPS; SNARE; phosphoinositides
MeSH headings : Arabidopsis / genetics; Arabidopsis / metabolism; Arabidopsis Proteins / genetics; Arabidopsis Proteins / metabolism; Membrane Fusion / physiology; Membrane Proteins / genetics; Membrane Proteins / metabolism; Phosphatidylinositol Phosphates / genetics; Phosphatidylinositol Phosphates / metabolism; Vacuoles / genetics; Vacuoles / metabolism; Vesicular Transport Proteins / genetics; Vesicular Transport Proteins / metabolism
TL;DR: It is shown that Arabidopsis HOPS subunits VPS33 and VPS41 accumulate in late endosomes and that VPS 41, but not VPS 33, accumulates in the tonoplast via a wortmannin-sensitive process, and that HOPS–SNARE interactions at the initial stage are similar to other eukaryotes.

JOURNAL OF EXPERIMENTAL BOTANY, 67(22), 6459–6472.

By: A. Alvarez n, S. Han n, M. Toyota *, C. Brillada n, J. Zheng n, S. Gilroy *, M. Rojas-Pierce  n

Contributors: A. Alvarez n, S. Han n, M. Toyota *, C. Brillada n, J. Zheng n, S. Gilroy *, M. Rojas-Pierce  n

author keywords: Amyloplasts; cytoskeleton; gravitropism; SNARE; vacuole; wortmannin
MeSH headings : Androstadienes / pharmacology; Arabidopsis / drug effects; Arabidopsis / growth & development; Arabidopsis / ultrastructure; Arabidopsis Proteins / genetics; Arabidopsis Proteins / physiology; Gravitropism / drug effects; Gravitropism / physiology; Hypocotyl / drug effects; Hypocotyl / growth & development; Microscopy; Qb-SNARE Proteins / genetics; Qb-SNARE Proteins / physiology; Vacuoles / drug effects; Vacuoles / physiology; Vacuoles / ultrastructure; Wortmannin
TL;DR: The highly restricted movement of amyloplasts in graviperceptive cells of zig-1 hypocotyls is overcome by wortmannin treatment, suggesting a physical association between amylplasts and the vacuole. (via Semantic Scholar)

Homotypic Vacuole Fusion Requires VTI11 and Is Regulated by Phosphoinositides

MOLECULAR PLANT, 7(6), 1026–1040.

By: J. Zheng n, S. Han n, M. Rodriguez-Welsh n & M. Rojas-Pierce  n

Contributors: J. Zheng n, S. Han n, M. Rodriguez-Welsh n & M. Rojas-Pierce  n

author keywords: vacuole; SNARE; phosphoinositides; membrane fusion; Wortmannin
MeSH headings : Androstadienes / pharmacology; Arabidopsis / drug effects; Arabidopsis / metabolism; Arabidopsis Proteins / metabolism; Chromones / pharmacology; Morpholines / pharmacology; Phosphatidylinositol Phosphates / metabolism; Phosphoinositide-3 Kinase Inhibitors; Qb-SNARE Proteins / metabolism; Vacuoles / metabolism; Wortmannin
TL;DR: A ubiquitous role of phosphoinositides in vacuole fusion is suggested, both during the development of the large central vacuoles and during the dynamic vacUole remodeling that occurs as part of stomata movements. (via Semantic Scholar)
