Soil alkalinity causes major reductions in yield and quality of crops worldwide. The plant root is the first organ sensing soil alkalinity, which results in shorter primary roots. However, the mechanism underlying alkaline stress-mediated inhibition of root elongation remains to be further elucidated. Here, we report that alkaline conditions inhibit primary root elongation of Arabidopsis (Arabi...

As illustrated in the preceding paper (Firestone, G. L., and Heath, E. C. (1981) J. Biol. Chem. 256, 13961403), the de novo synthesis of a cell surface-localized glycoprotein that exhibits alkaline phosphatase activity was induced by treatment of mouse L-cell cultures with dibutyryl cyclic AMP. When the exposure of L-cell cultures to dibutyryl cyclic AMP was carried out in the presence of inhib...

INTRODUCTION Alkaline agarose gels are run at a pH that is sufficiently high to denature double-stranded DNA. The denatured DNA is maintained in a single-stranded state and migrates through the alkaline gel as a function of its size. Alkaline agarose gels are used chiefly to measure the size of first and second strands of cDNA (Construction of cDNA Libraries Stage 1: Synthesis of First-strand c...

HUMAN INTESTINAL ALKALINE PHOSPHATASE. Tissue expression and serum levels. ISBN 91-7174-674-9 ISSN 0346-6612 New series No 342 Ulla Domar, Department of Medical Biochemistry and Biophysics, University of Umeå, S-90187 Umeå, Sweden. Human alkaline phosphatase (ALP) comprises four isozymes, viz liver/bone/ kidney or tissue unspecific (AP), intestinal (LAP), placental (PLAP) and germ cell or PLAP-...

Storage of photovoltaic and wind electricity in batteries could solve the mismatch problem between the intermittent supply of these renewable resources and variable demand. Flow batteries permit more economical long-duration discharge than solid-electrode batteries by using liquid electrolytes stored outside of the battery. We report an alkaline flow battery based on redox-active organic molecu...

Creating an alkaline environment prior to 10-methacryloyloxydecyldihydrogenphosphate (MDP) conditioning improves the resin bonding of zirconia. The present study evaluated the effects of four alkaline coatings with different water solubilities and pH values on resin bonding of MDP-conditioned zirconia. Two alkaline nanoparticle coatings were studied in particular. Thermodynamics calculations we...

Tissue nonspecific alkaline phosphatase, promoting arterial calcification in experimental models, is a powerful predictor of total and cardiovascular mortality in general population and in patients with renal or cardiovascular diseases. For this study, to evaluate a possible correlation between serum alkaline phosphatase levels and endothelial function, assessed by strain gauge plethysmography,...

The biological significance of polyoxometalates is well renowned owing to their anticancer, antiviral and antibiotic properties. Here another therapeutic aspect of polyoxometalates has been explored as alkaline phosphatase inhibitors along with the remarked anticancer and amoebicidal properties. Synthesis and inhibitory studies of a set of seven polyoxotungstates against two major isozymes of a...

Germination and early seedling growth are the most critical periods for plant establishment in saline-alkaline soil, the main factor limiting plant growth and production worldwide. To explore the physiological adaptive mechanisms of the two stages under saline and alkaline conditions, Leymus chinensis was tested by mixing two neutral salts (NaCl: Na2SO4) and two alkaline salts (NaHCO3: Na2CO3)....

1. Liver and bone alkaline phosphatase isoenzymes were solubilized with the zwitterionic detergent sulphobetaine 14, and purified to homogeneity by using a monoclonal antibody previously raised against a partially-purified preparation of the liver isoenzyme. Both purified isoenzymes had a specific activity in the range 1100-1400 mumol/min per mg of protein with a subunit Mr of 80,000 determined...
