BACKGROUND Plasma membrane Ca(2+)ATPase is a transport protein in the plasma membrane of cells and helps in removal of calcium (Ca(2+)) from the cell, hence regulating Ca(2+) level within cells. Though plant Ca(2+)ATPases have been shown to be involved in plant stress responses but their promoter regions have not been well studied. RESULTS The 1478 bp promoter sequence of rice plasma membrane...

In poplars (Populus), bspA encodes a 32-kD bark storage protein that accumulates in the inner bark of plants exposed to either short-day (SD) photoperiods or elevated levels of nitrogen. In this study, poplars transformed with a chimeric gene consisting of the bspA promoter fused to beta-glucuronidase (uidA) were used to investigate the transcriptional regulation of the bspA promoter. Photoperi...

adsorption of anilofos was studied in four soils (topsoil from alfisol, inceptisol, oxisol and vertisol). the order of adsorption of anilofos was vertisol > oxisol > alfisol > inceptisol. the soil sorption coefficient k and the soil organic carbon sorption coefficient koc are the basic parameters used for describing the environmental fate of the herbicides. in top soil the calculated k values w...

OBJECTIVE To identify clinical and serological differences of patients with reactive arthritis after infection with Lancefield group A beta-haemolytic streptococci (GAS), compared with non-group A-that is, group C or G streptococci (NGAS:GCS/GGS), and a group of culture negative or unidentified streptococci (GUS). METHODS A prospective study of consecutive patients with reactive arthritis aft...

Using a beta-glucuronidase (GUS) reporter-COP1 fusion transgene, it was shown previously that Arabidopsis COP1 acts within the nucleus as a repressor of seedling photomorphogenic development and that high inactivation of COP1 was accompanied by a reduction of COP1 nuclear abundance (A.G. von Arnim, X.-W. Deng [1994] Cell 79: 1035-1045). Here we report that the GUS-COP1 fusion transgene can comp...

Problem statement: The heterogeneity in the choice of simulation platforms for real time scheduling stands behind the difficulty of developing a common simulation environment. A Discrete Event Simulation (DES) for a real time scheduling domain encompassing event definition, time advancing mechanism and scheduler has yet to be developed. Approach: The study focused on the proposed and the develo...

E. coli β-glucuronidase (GUS) activity assays are routinely used in fields such as plant molecular biology, applied microbiology and healthcare. Methods based on the optical detection of GUS using synthetic fluorogenic substrates are widely employed since they don't require expensive instrumentation and are easy to perform. In this study three fluorogenic substrates and their respective fluorop...
