Fusarium tucumaniae is the only known sexually reproducing species among the seven closely related fusaria that cause soybean sudden death syndrome (SDS) or bean root rot (BRR). In a previous study, laboratory mating of F. tucumaniae yielded recombinant ascospore progeny but required two mating-compatible strains, indicating that it is heterothallic. To assess the reproductive mode of the other...

Sodium dodecyl sulfate (SDS) sedimentation volume has long been used to characterize wheat flours and meals with the aim of predicting processing and end-product qualities. In order to survey the influence of low-molecular-weight glutenin subunits (LMW-GSs) at Glu-B3 locus on wheat SDS sedimentation volume, a total of 283 wheat (Triticum aestivum L.) varieties including landraces and improved a...

Department of Medical Microbiology, University of Z/irich, 8028 Z/irich, Switzerland A large number of different protocols for the efficient isolation of highly purified DNA from eukaryotic and prokaryotic cells is extant. (1-4) These procedures usually include treatment with proteinase K in the presence of SDS, which efficiently lyses the cells and nuclei and liberates the DNA tightly bound in...

BACKGROUND Shwachman-Diamond Syndrome (SDS) is a hereditary disease caused by mutations in the SBDS gene. SDS is clinically characterized by pancreatic insufficiency, skeletal abnormalities and bone marrow dysfunction. The hematologic abnormalities include neutropenia, neutrophil chemotaxis defects, and an increased risk of developing Acute Myeloid Leukemia (AML). Although several studies have ...

BACKGROUND The HBV-X (HBX) protein is believed to contribute to the development of HCC. However, the molecular mechanisms involved in HBX- mediated hepatocarcinogenesis remain obscure. In this study, the effect of hepatitis B virus X gene and its protein product HBxAg on expression of p53 gene in Hep G2 cell line was investigated. METHODS Viral DNA extracted from HBV-positive serum and HBX ge...

The gene encoding MPB51 was amplified from M. bovis Valleel11 chromosomal DNA using PCR technique, and the PCR product was approximately 800 bp DNA segment. Using T-A cloning technique, the PCR product was cloned into pGEM-T vector and cloning plasmid pGEM-T-51 was thus constructed successfully. pGEM-T-51 and pET28a( + ) were digested by BamH I and EcoR I double enzymes. The purified MPB51 gene...
