Molecular cloning and functional expression in bacteria of the potassium transporters CnHAK1 and CnHAK2 of the seagrass Cymodocea nodosa
The cDNAs CnHAK1 and CnHAK2 , encoding K + transporters, were amplified from the leaves of the seagrass Cymodocea nodosa . None of these transporters...

Salinity stress-tolerant and -sensitive rice (Oryza sativa L.) regulate AKT1-type potassium channel transcripts differently
In the indica rice ( Oryza sativa L.) a cDNA was characterized that encoded OsAKT1 homologous to inward-rectifying potassium channels of the AKT/KAT...

Plants and sodium ions: kee** company with the enemy
Plants face a dilemma about sodium metabolism. Uptake of ubiquitous sodium ions is desirable as a way to build osmotic potential, absorb water and...

Cells: Functional Units of TCLs
Higher plants develop from a single-celled zygote into a multicellular organism through co-ordinated cell divisions, and when this process occurs...

Molecular mechanisms of potassium and sodium uptake in plants
Potassium (K+) is an essential nutrient and the most abundant cation in plants, whereas the closely related ion sodium (Na+) is toxic to most plants...

Monitoring large-scale changes in transcript abundance in drought- and salt-stressed barley
Responses to drought and salinity in barley ( Hordeum vulgare L. cv. Tokak) were monitored by microarray hybridization of 1463 DNA elements derived...

Genetics of Salinity Responses and Plant Breeding
Molecular biology offers the possibility of designing new plant genotypes with enhanced resistance to salinity. This does not, however, mean that...

Molecular Markers and Abiotic Stresses
In most moderate climates plants encounter a variety of abiotic stress conditions during the growing season which significantly impact their...

Molecular mechanisms of potassium and sodium transport in plants
Potassium is an important macronutrient in higher plants and K+ transporters play important roles in many physiological processes. Furthermore,...

Potassium and Sodium Fluxes in the PhytopathogenicFungus Fusarium oxysporum var. lini
Rubidium uptake in potassium-starved cells followed biphasic kinetics in the micromolar and millimolar range and was independent of the temperature....

Salt Tolerance Engineering—Which are the essential mechanisms?
High soil salinity poses a problem to many agriculturally useable areas in the world and it can be expected that this problem becomes more severe...

Control of Bacterial Iron Transport by Regulatory Proteins
It has been postulated that pyrite (FeS2) metabolism was the basis for the early evolution of life (Wächtershäuser 1990). As a consequence, iron is...

The molecular basis of potassium nutrition in plants
Over the last five years, the cloning and characterization of K+ transport genes corresponding to K+ channels (KAT1, AKT1, KST1, AKT2), associated...

Spatio-temporal regulation of glycosis and oxidative phosphorylation in vivo
The aim of this chapter is to present some recent advances in the in vivo control and regulation of glycolysis and oxidative phosphorylation with...
