Journal ArticleDOI
A hypothesis relating critical potassium concentrations for growth to the distribution and functions of this ion in the plant cell
Roger A. Leigh,R. G. Wyn Jones +1 more
TL;DR: A model is proposed in which, as the concentration of K in the tissue declines, the concentration in the cytoplasm is initially maintained constant, while that in the vacuole decreases, and the hypothesis explains the observed relationships between growth and concentrations of K.
Journal ArticleDOI
Nicotianamine chelates both FeIII and FeII. Implications for metal transport in plants
Nicolaus von Wirén,Sukhbinder Klair,Suhkibar Bansal,Jean-François Briat,Hicham Khodr,Takayuki Shioiri,Roger A. Leigh,Robert C. Hider +7 more
TL;DR: Capillary electrophoresis showed that in the presence of FeII and FeIII, NA preferentially chelates FeII, indicating that the FeIINA complex is kinetically stable under aerobic conditions and suggests that NA will have an important role in scavenging Fe and protecting the cell from oxidative damage.
Journal ArticleDOI
Potassium homeostasis in vacuolate plant cells
TL;DR: Measurements of the changes in K+ activity in the vacuole and cytosol of barley root cells revealed that vacuolar aK declined linearly with decreases in tissue K+ concentration, whereas cytosolic aK initially remained constant in both epidermal and cortical cells but then declined at different rates in each cell type.
Journal ArticleDOI
Nomenclature for HKT transporters, key determinants of plant salinity tolerance
J. Damien Platten,Olivier Cotsaftis,Pierre Berthomieu,Hans J. Bohnert,Romola Davenport,David J. Fairbairn,Tomoaki Horie,Roger A. Leigh,Hong-Xuan Lin,Sheng Luan,Pascal Mäser,Omar Pantoja,Alonso Rodríguez-Navarro,Daniel P. Schachtman,Julian I. Schroeder,Hervé Sentenac,Nobuyuki Uozumi,Anne-Aliénor Véry,Jian-Kang Zhu,Elizabeth S. Dennis,Mark Tester +20 more
TL;DR: There is evidence indicating a central role for members of the HKT gene family of Na+ and Na+/K+ transporters in controlling Na+ accumulation in the shoot and, thus, in determining salinity tolerance in Arabidopsis and rice.
Book
Long-term Experiments in Agricultural and Ecological Sciences
TL;DR: This book demonstrates that long-term experimentation and monitoring are vitally important in understanding changes that are occurring in the ecosystems and will interest a very wide range of readers in agronomy, soil science, forestry, ecology and environmental science.
