J Exp Bot
. 2017 Mar;
68(12):3165-3178.
PMID: 28338823
Flowering plant genomes encode multiple cation/H+ exchangers (CHXs) whose functions are largely unknown. AtCHX17, AtCHX18, and AtCHX19 are membrane transporters that modulate K+ and pH homeostasis and are localized in...

Biochim Biophys Acta
. 2016 May;
1858(9):1983-1998.
PMID: 27179641
Using Arabidopsis thaliana AtCHX17 as an example, we combine structural modeling and mutagenesis to provide insights on its protein architecture and transport function which is poorly characterized. This approach is...

Mol Plant
. 2013 Feb;
6(4):1226-46.
PMID: 23430044
The importance of sorting proteins and wall materials to their destination is critical for plant growth and development, though the machinery orchestrating membrane trafficking is poorly understood. Transporters that alter...

J Biol Chem
. 2011 Jul;
286(39):33931-41.
PMID: 21795714
The complexity of intracellular compartments in eukaryotic cells evolved to provide distinct environments to regulate processes necessary for cell proliferation and survival. A large family of predicted cation/proton exchangers (CHX),...

Plant Physiol
. 2008 Aug;
148(2):796-807.
PMID: 18676662
Potassium (K+) homeostasis is essential for diverse cellular processes, although how various cation transporters collaborate to maintain a suitable K+ required for growth and development is poorly understood. The Arabidopsis...

Plant Physiol
. 2007 Mar;
144(1):82-93.
PMID: 17337534
Guard cell movement is induced by environmental and hormonal signals that cause changes in turgor through changes in uptake or release of solutes and water. Several transporters mediating these fluxes...

Bock K, Honys D, Ward J, Padmanaban S, Nawrocki E, Hirschi K, et al.
Plant Physiol
. 2006 Apr;
140(4):1151-68.
PMID: 16607029
Male fertility depends on the proper development of the male gametophyte, successful pollen germination, tube growth, and delivery of the sperm cells to the ovule. Previous studies have shown that...

. 2004 Mar;
134(4):1514-26.
PMID: 15051861
Acidification of intracellular compartments by the vacuolar-type H(+)-ATPases (VHA) is known to energize ion and metabolite transport, though cellular processes influenced by this activity are poorly understood. At least 26...

Trends Plant Sci
. 2002 Apr;
7(4):157-61.
PMID: 11950611
The vacuolar-type H(+)-ATPase acidifies intracellular compartments and is essential for many processes, including cotransport, guard cell movement, development, and tolerance to environmental stress. We have identified at least 26 genes...
