Identification of growth-related tonoplast proteins in Arabidopsis thaliana
… of solutes over the vacuolar membrane (the tonoplast) and by controlling the water channels, the aquaporins. Together with the control of cell wall relaxation, vacuolar osmotic pressure regulation is thought to play an important role in cell expansion, directly by providing cell volume and …

Korrelative licht- und elektronenmikroskopische Untersuchungen zu Tonoplast intrinsischen Proteinen als Merkmale verschiedener Vakuolentypen
… auch anhand verschiedener Isoformen der in ihren Tonoplasten enthaltenen Aquaporine, den „tonoplast intrinsic proteins“ (TIPs). Dabei wird alpha-TIP im Tonoplast als Merkmal für Proteinspeichervakuolen und gamma-TIP als Merkmal für den Tonoplast lytischer Vakuolen angesehen. Ausgehend von dieser …

Atpase and Protein Kinase in Membranes From Corn Roots: Regulation of Tonoplast Atpase by Calmodulin or by Protein Kinase
A study was conducted to find if microsomal H('+)-ATPases from corn roots are regulated by Ca('2+)- or calmodulin (CaM)-dependent protein phosphorylation. This work included: (a) identifying the microsomal H('+)-ATPases; (b) characterizing protein kinase and phosphatase activities in microsomal …

Photodynamic Herbicide Modulators
… mesophyll cells. These changes consisted of: tonoplast rupture and separation of the plasma membrane from the cell wall, this in turn led to increased membrane permeability and severe plasmolysis, rupture of chloroplast membranes and ultimately chloroplast breakdown. The massive accumulation …

Characterisation of putative metal transport proteins in the nickel hyperaccumulator Senecio coronatus: investigating candidate genes for nickel tolerance and accumulation
… MATE localises to the nucleus and VIT to the tonoplast or plasma membrane.

Gene discovery in Catharanthus roseus using virus induced gene silencing
… identification of two proteins that act as trans-tonoplastic transporters in MIA metabolism. The multidrug and toxic compound extrusion (MATE) protein, CrMATE1952, was localised to the vacuolar membrane and silencing its expression in planta resulted in the accumulation of a secologanin …

Ultrastructural cytology of peanut infected with peanut stripe virus
… in linear arrays along the inner surface of the tonoplast. Membrane and organelle degradation was evident in cells infected with either isolate of the virus. Numerous cytoplasmic inclusions and virus particles were observed in cells from light green areas of the leaf. Cells from dark green areas …

Elektrophysiologische Untersuchungen an einzelligen marinen Riesenalgen
… elektrischen Eigenschaften von Plasmalemma und Tonoplast durch gezielte Manipulation des vakuolären und externen Mediums. Dabei kann der für die Physiologie der Zellen wichtige hydrostatische Innendruck (Turgor) ständig kontrolliert werden. Die Applikation eines Ladungspulses resultierte bei …

Characterisation of the PQ-loop repeat membrane protein family in arabidopsis thaliana
… AtPQL1 and AtPQL5-GFP fusions both highlight the tonoplast whereas AtPQL4 and AtPQL6-GFP appear to highlight the ER. A number of knockout and over-expresser mutants were isolated for each gene. Although no physiological phenotype could be found, mutants with altered expression of AtPQL4 and …

Study of wound healing and the involvement of the cytoskeleton in Vaucheria longicaulis variety macounii
… by the fusion of the plasma membrane and tonoplast at the wound site. Organelles then accumulate at the membranous barrier created by the sealing off procedure. This is followed by chloroplast retraction and return to the wound site, concurrent with restoration of turgor pressure in late …

Salt stress responses in pear and quince: physiological and molecular aspects
… determinants in the “SOS” pathway: NHX1 (tonoplast Na+/H+ antiporter), SOS1 (plasmalemma Na+/H+ antiporter) and HKT1 (K+ high-affinity and Na+ low-affinity transporter). These studies showed that two quince rootstocks adopted different responsive mechanisms to NaCl stress. BA29 increased …

Transcriptomic characterization of soybean – sclerotinia sclerotiorum interaction at early infection stages
… patterns were discussed; for example, a tonoplast dicarboxylate transporter that could be involved in the maintenance of cellular pH homeostasis was only induced in OxO but suppressed by other treatment with the presence of high levels of oxalic acid. Most of the genes annotated as …
