The aluminum (Al)-induced secretion of citrate has been regarded as an important mechanism for Al resistance in soybean (Glycine max). However, the mechanism of how Al induces citrate secretion remains unclear. In this study, we investigated the regulatory role of plasma membrane H+-ATPaSe on the Al-induced secretion of citrate from soybean roots. Experiments performed with plants grown in full nutrient solution showed that Al-induced activity of plasma membrane H+-ATPase paralleled secretion...

Citrate Secretion Coupled with the Modulation of Soybean Root Tip under Aluminum Stress. Up-Regulation of Transcription, Translation, and Threonine-Oriented Phosphorylation of Plasma Membrane H+-ATPase1
Plant Physiology ; The aluminum (Al)-induced secretion of citrate has been regarded as an important mechanism for Al resistance in soybean (Glycine max). However, the mechanism of how Al induces citrate secretion remains unclear. In this study, we investigated the regulatory role of plasma membrane H+-ATPaSe on the
Energization of Transport Processes in Plants. Roles of the Plasma Membrane H+-ATPase1
Plant Physiology ; Much has been learned about the energization of nutrient transport since Hoagland in 1944 gave his famous series of lectures on plant nutrition. Already at that time it was speculated that energy for transport of solutes into cells was provided by compounds containing energy-rich phosphate bonds
Selective Mobility and Sensitivity to SNAREs Is Exhibited by the Arabidopsis KAT1 K+ Channel at the Plasma Membrane[W]
Plant Cell ; Recent findings indicate that proteins in the SNARE superfamily are essential for cell signaling, in addition to facilitating vesicle traffic in plant cell homeostasis, growth, and development. We previously identified SNAREs SYP121/Syr1 from tobacco (Nicotiana tabacum) and the Arabidopsis thaliana
Expression of a Constitutively Activated Plasma Membrane H+-ATPase Alters Plant Development and Increases Salt Tolerance1[C][OA]
Plant Physiology ; The plasma membrane proton pump ATPase (H+-ATPase) plays a major role in the activation of ion and nutrient transport and has been suggested to be involved in several physiological processes, such as cell expansion and salt tolerance. Its activity is regulated by a C-terminal autoinhibitory domain
The two major types of plant plasma membrane H+-ATPases show different enzymatic properties and confer differential pH sensitivity of yeast growth
Plant Physiology ; The Two Major Types of Plant Plasma Membrane H+-ATPases Show Different Enzymatic Properties and Confer Differential pH Sensitivity of Yeast Growth1 Abbreviation: LPC, lysophosphatidylcholine. The proton-pumping ATPase (H+-ATPase) of the plant plasma membrane is encoded by two major gene
A phosphothreonine residue at the C-terminal end of the plasma membrane H+-ATPase is protected by fusicoccin-induced 14-3-3 binding

Arabidopsis Protein Kinase PKS5 Inhibits the Plasma Membrane H+-ATPase by Preventing Interaction with 14-3-3 Protein
Plant Cell ; Regulation of the trans-plasma membrane pH gradient is an important part of plant responses to several hormonal and environmental cues, including auxin, blue light, and fungal elicitors. However, little is known about the signaling components that mediate this regulation. Here, we report that an
Seasonal changes of plasma membrane H+ -ATPase and endogenous ion current during cambial growth in poplar plants
Plant Physiology ; Seasonal Changes of Plasma Membrane H+-ATPase and Endogenous Ion Current during Cambial Growth in Poplar Plants1 The plasma membrane H+-ATPase (PM H'-ATPase), potassium ions, and endogenous ion currents might play a fundamental role in the physiology of cambial growth. Seasonal changes of these
An Arabidopsis thaliana Plasma Membrane Proton Pump Is Essential for Pollen Development
Genetics ; ABSTRACT The plasma membrane proton pump (H^sup ATPase) found in plants and fungi is a P-type ATPase with a polypeptide sequence, structure, and in vivo function similar to the mammalian sodium pump (Na^sup K^sup ATPase). Despite its hypothetical importance for generating and maintaining the
Adaptation of H+ -pumping and plasma membrane H+ ATPase activity in proteoid roots of white lupin under phosphate deficiency
Plant Physiology ; Adaptation of H^sup Pumping and Plasma Membrane H^sup +^ ATPase Activity in Plasma Meoid Roots of White Lupin under Phosphate Deficiency1 White lupin (Lupinus albus) is able to adapt to phosphorus deficiency by producing proteoid roots that release a huge amount of organic acids, resulting in
