The human F8/G253 antigen, B-CAM, is a cell surface glycoprotein that is expressed with restricted distribution pattern in normal fetal and adult tissues, and is up-regulated following malignant transformation in some cell types. We have isolated a complementary DNA for B-CAM using an expression cloning technique. The complementary DNA (EMBL accession number X80026) encodes a 588-amino acid pro...

SYNOPSIS. Congenic strains of syngen 1, Tetrahymena pyriformis, were produced by backcrossing the FI hybrid between inbred strains C2 and D to strain D in 12 consecutive backcrosses, with selection for certain C2 genes, and then using genomic exclusion to induce homozygosity. Six congenic strains of high breeding performance are available. Five differ from strain D in single genes at 5 differen...

The dissociation constants for the binding of Rhodobacter capsulatus cytochrome c2 and its K93P mutant to the cytochrome bc1 complex embedded in a phospholipid bilayer were measured by plasmon waveguide resonance spectroscopy in the presence and absence of the inhibitor stigmatellin. The reduced form of cytochrome c2 strongly binds to reduced cytochrome bc1 (Kd = 0.02 microM) but binds much mor...

Although highly controversial, the hypothesis of a link between aluminum (Al) in drinking water and Alzheimer's disease (AD) has been supported by several epidemiological studies. Transferrin (Tf) is a major transport protein for both iron and Al. Moreover, it has been demonstrated that defective binding of iron and Al to the Tf variant C2 could be present in AD. Individuals carrying the Tf C2 ...

Knowledge of gene actions governing begomovirus resistance and plant architectural traits is a prerequisite for successful hybrid breeding programme. Therefore, the associated with these were studied in two intervarietal crosses Cucurbita moschata (C1: Punjab Nawab × MVSR-6711 C2: Nawab P-135). We used generation mean analysis six generations this purpose. Significant differences between...

Staniaszek M., Szczechura W., Marczewski W. (2014): Identification of a new molecular marker C2-25 linked to the Fusarium oxysporum f.sp. radicis-lycopersici resistance Frl gene in tomato. Czech J. Genet. Plant Breed., 50: 285–287. Fusarium oxysporum Schlecht. f.sp. radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in...

The phoN gene of Salmonella enterica sv. Typhimurium strain MD6001 was cloned in the multicopy plasmid pBluescript SK(-). The nucleotide sequence of the cloned gene differs from the corresponding S. typhimurium LT2 sequence at 23 residues, leading to 15 amino-acid differences, but was very close to the S. typhi phoN sequence (only three nucleotide and two amino-acid differences). The recombinan...

BACKGROUND Chlamydia trachomatis is globally the predominant infectious cause of blindness and one of the most common bacterial causes of sexually transmitted infection. Infections of the conjunctiva cause the blinding disease trachoma, an immuno-pathological disease that is characterised by chronic conjunctival inflammation and fibrosis. The polymorphic Killer-cell Immunoglobulin-like Receptor...

PURPOSE To determine whether genetic variants in the complement component 2 and factor B gene (C2/CFB) locus are associated with the risk for typical age-related macular degeneration (AMD) or polypoidal choroidal vasculopathy (PCV) in a Japanese population. METHODS Four single nucleotide polymorphisms (SNPs) were genotyped across the C2/CFB locus of patients with typical AMD (n = 455) or PCV ...

Lignin is a phenolic heteropolymer that is deposited in secondary-thickened cell walls, where it provides mechanical strength. A recent structural characterization of cell walls from monocot species showed that the flavone tricin is part of the native lignin polymer, where it is hypothesized to initiate lignin chains. In this study, we investigated the consequences of altered tricin levels on l...
