Genes Involved in Osmoregulation during Turgor-Driven Cell Expansion of Developing Cotton Fibers Are Differentially Regulated1

Smart, Lawrence B., Vojdani, Fakrieh, Maeshima, Masayoshi, Wilkins, Thea A.

Cotton (Gossypium hirsutum L.) fibers are single-celled trichomes that synchronously undergo a phase of rapid cell expansion, then a phase including secondary cell wall deposition, and finally...

Molecular Cloning of Vacuolar H+-Pyrophosphatase and Its Developmental Expression in Growing Hypocotyl of Mung Bean1

Nakanishi, Yoichi, Maeshima, Masayoshi

Vacuolar proton-translocating inorganic pyrophosphatase and H+-ATPase acidify the vacuoles and power the vacuolar secondary active transport systems in plants. Developmental changes in the...

Purification, Properties, and Molecular Cloning of a Novel Ca2+-Binding Protein in Radish Vacuoles1

Yuasa, Koji, Maeshima, Masayoshi

To understand the roles of plant vacuoles, we have purified and characterized a major soluble protein from vacuoles of radish (Raphanus sativus cv Tokinashi-daikon) taproots. The results showed that...

Arabidopsis Immunophilin-like TWD1 Functionally Interacts with Vacuolar ABC Transporters

Geisler, Markus, Girin, Marjolaine, Brandt, Sabine, Vincenzetti, Vincent, Plaza, Sonia, Paris, Nadine, ...

Previously, the immunophilin-like protein TWD1 from Arabidopsis has been demonstrated to interact with the ABC transporters AtPGP1 and its closest homologue, AtPGP19. Physiological and biochemical...

Purification and Properties of Glyoxysomal Lipase from Castor Bean 1

Maeshima, Masayoshi, Beevers, Harry

The alkaline lipase in the glyoxysomes from the endosperm of young castor bean seedlings, an integral membrane component, was solubilized in deoxycholate:KCl and purified to apparent homogeneity. The...

Mechanism of the Decline in Vacuolar H+ -ATPase Activity in Mung Bean Hypocotyls during Chilling 1

Matsuura-Endo, Chie, Maeshima, Masayoshi, Yoshida, Shizuo

The mechanism responsible for the decrease in the activity of vacuolar H+ -ATPase during chilling was investigated in seedlings of mung bean (Vigna radiata). After chilling at 0°C for 3 d, the...

Characterization of the Major Integral Protein of Vacuolar Membrane 1

Maeshima, Masayoshi

The vacuolar membrane of radish (Raphanus sativus) taproot contained a large quantity of a protein of 23 kilodaltons that accounted for more than 25% of the total membrane proteins. The protein,...

The protein storage vacuole: a unique compound organelle

Jiang, Liwen, Phillips, Thomas E., Hamm, Christopher A., Drozdowicz, Yolanda M., Rea, Philip A., Maeshima, Masayoshi, ...

Storage proteins are deposited into protein storage vacuoles (PSVs) during plant seed development and maturation and stably accumulate to high levels; subsequently, during germination the storage...

Deletion of a Histidine-rich Loop of AtMTP1, a Vacuolar Zn2+/H+ Antiporter of Arabidopsis thaliana, Stimulates the Transport Activity*

Kawachi, Miki, Kobae, Yoshihiro, Mimura, Tetsuro, Maeshima, Masayoshi

Arabidopsis thaliana AtMTP1 belongs to the cation diffusion facilitator family and is localized on the vacuolar membrane. We investigated the enzymatic kinetics of AtMTP1 by a heterologous expression...
