Raspberries (Rubus spp.) exhibit a unique rooting process that is initiated from the stem apex of primocane, conferring an unusual asexual mode of reproduction to this plant. However, the full complement of genes involved in this process has not been identified. To this end, the present study analyzed the transcriptomes of the Rubus primocane and floricane stem apex at three developmental stage...

OBJECTIVES To ascertain the effects of subinhibitory concentrations of several antifungal agents on a virulence factor: secreted proteinase (Sap) activity and expression of SAP genes in Candida albicans. METHODS Enzyme assays and growth measurements, GFP-SAP2 promoter constructs and fluorescence measurement, transcript profiling and RT-PCR. RESULTS For seven of eight C. albicans isolates te...

Secreted aspartyl proteinases (Saps), encoded by a gene family with at least nine members (SAP1 to SAP9), are one of the most discussed virulence factors produced by the human pathogen Candida albicans. In order to study the role of each Sap isoenzyme in pathogenicity, we have constructed strains which harbor mutations at selected SAP genes. SAP1, SAP2, and SAP3, which are regulated differentia...

Cytochrome P450 1A1 (CYP1A1) is a heme-containing mono-oxygenase involved in metabolism of environmental contaminants. Two variants of dog CYP1A1 with a single residue difference were identified and designated Sap1 and Sap2. Compared with Sap1, Sap2 had a Trp50Leu substitution. The biochemical characteristics of the variants were comparatively analyzed using heterologous expression in Escherich...

UNLABELLED Vaginal inflammation (vaginitis) is the most common disease caused by the human-pathogenic fungus Candida albicans. Secretory aspartyl proteinases (Sap) are major virulence traits of C. albicans that have been suggested to play a role in vaginitis. To dissect the mechanisms by which Sap play this role, Sap2, a dominantly expressed member of the Sap family and a putative constituent o...

objective: the secreted aspartic proteinases (sap2) of candida albicans has prominent role on candida adherence, invasion, and pathogenicity. the aim of this study was cloning, expression and characterizing of sap2 enzyme. also in this study for the first time, the expression system p. pasturis was used for expressing the recombinant protein. materials and methods: c. albicans sap2 gene was am...

The endothelial cell interactions of homozygous null mutants of Candida albicans that were deficient in secreted aspartyl proteinase 1 (Sap1), Sap2, or Sap3 were investigated. Only Sap2 was found to contribute to the ability of C. albicans to damage endothelial cells and stimulate them to express E-selectin. None of the Saps studied appears to play a role in C. albicans adherence to endothelial...

The secreted aspartyl proteinases of Candida albicans (products of the SAP genes) are thought to contribute to virulence through their effects on Candida adherence, invasion, and pathogenicity. From a single strain of C. albicans (WO-1) which expresses a phenotypic switching system, three secreted aspartyl proteinases have been identified as determined by molecular weight and N-terminal sequenc...
