Magnesium accumulates at high concentrations in dicotyledonous leaves but it is not known in which leaf cell types it accumulates, by what mechanism this occurs and the role it plays when stored in the vacuoles of these cell types. Cell-specific vacu

Cytosolic K + activity in plant cells is about 80 mM and is maintained during moderate K + -deprivation. It decreases to much lower values only in extreme K + -deficiency. In contrast, the vacuolar K + concentration responds directly to the K + suppl

The effect of different rates of potassium (K) fertilizer on the yield and quality of sugar beet was studied in a series of 26 trials on soils of different type and K index between 1992 and 1997. There were few yield responses even though the majorit

In barley (Hordeum vulgare L.) leaves, differential ion accumulation commonly results in inorganic phosphate (Pi) being confined to the mesophyll and Ca2+ to the epidermis, with preferential epidermal accumulation of Cl−, Na+, and some other ions.

Nicotianamine (NA) occurs in all plants and chelates metal cations, including FeII, but reportedly not FeIII. However, a comparison of the FeII and ZnII affinity constants of NA and various FeIII-chelating aminocarboxylates suggested that NA should c

The bisphosphonates (general structure PO3-R-PO3) competitively inhibit soluble and membrane-bound inorganic pyrophosphatases (PPases) with differing degrees of specificity. Aminomethylenebisphosphonate (AMBP; HC(PO3)2NH2) is a potent, specific inhib

Agar and agarose gels were evaluated as systems to mechanically impede roots of rice (Oryza sativa L.). Two-layer gels were used so that seedlings established in a layer of weak gel (0.35% weight/volume) and then grew downwards to encounter a treatme

Ion transport across the plasma membrane of suspension-culture cells derived from immature barley embryos has been studied in low (15 mM KCl) and high (additional 150 mM NaCl) salt conditions to understand how plants discriminate between K(+) and Na(
